"Jackass!" "Everything okay, Mr. C.?" "Does everything look okay, Pi?" "!" "Uh, I don't know." "It's kinda dark in here." "Dad?" "Wh-what's going on?" "What happened?" "My office." "Now." "I've tried to be generous and understanding." "I have tried to be tolerant." "But, Alexis, it's been over a month, and Pi is still here." "I know, dad." "And he feels bad about it." "We both do." "I don't care if he feels bad." "I want my couch back." "I want my house back." "You go back to college next week." "What then?" "Sweetheart, he has to go." "You're absolutely right." "He's been here way too long." "It's not right, and it's not fair to you." "Thank you." "You're welcome." "And the best news is, I think we found a place." "Honey, that is so great." "Did you say "we found a place"?" "Yeah." "Pi and I talked it over." "He can't afford a place on his own, so we found one together." " Together?" " Yeah." "That way, the rent's totally affordable." "I can cover my half with a work-study job," " and it's right next to school." "Plus it'll save you having to pay for university housing this year." "You don't honestly think I'm gonna let you do this, do you?" "Let me?" "Dad, I'm 19." "Exactly my point." "Far too young to be moving in with someone." "Really?" "Because I was old enough to sign the lease." "And weren't you living with your girlfriend" " when you were 19?" " Yes." "But that was different." "How?" "Trust me, dad." "We've thought this through." "It makes total sense." "In what universe does that make sense?" "I'll tell you what universe...the one where she's blinded by emotion and not thinking straight." "It's like watching a car accident in slow motion." "You know, Castle, my dad wanted to kill the first guy that I moved in with." "He did everything he could to try and talk me out of it, and all that did was make me want to do it even more." "I wish her future self would come back and talk to her present self, let her know what a mistake she's making, save her from a..." "A world of hurt." "What happened?" "A lot of weirdos out there with too much imagination is what happened." "And, yes, I'm looking at you, Castle." "Yeah, except I only commit my murders on paper." "I don't actually do them." "A lot more lucrative, a lot less prison." "So was she electrocuted?" "Yeah, but that's not the cause of death." "Her throat was cut." "And the rest of this, if I had to guess, I'd say she was tortured." "Why?" "Who is she?" "Shauna Taylor, 34." "She's a parole office with the department of corrections." "Could be one of her parolees out for revenge." "How did he get in?" "Right now it's a mystery." "There's no sign of forced entry, and from the look of it," " she wasn't expecting trouble." " How can you tell that?" "She had a carry permit for a SIG .9." "Still in the top drawer of her nightstand." "Do we know when this happened?" "I won't have anything definitive until I get her back to the office." "Neighbors didn't hear anything, probably because she was gagged." "But the guy who called it in said that he saw a guy leaving the apartment around 5:30 A.M." "Said the dude had fresh blood on him." "Ryan's got our witness with the sketch artist now." "Okay, contact DOC, get a list of all of her parolees, see if there's a match." "We're also gonna need alibis for all of them from last night." "What do we know about her family?" "She's dead?" "I knew it!" "I knew something like this would happen." "I warned her, didn't I?" "She loved her job." "She loved helping people get their lives back on track." "Dr. Wickfield, were you and your stepsister close?" "Not really." "The two of us had very different lives." "Since our father passed, we made an effort, called each other once, maybe twice a month." "And when you last spoke to her, did she say anything that would indicate she was in trouble?" "Yeah." "When we--we talked about a week ago." "She said she thought someone might be stalking her." "She kept seeing this guy wherever she went, watching her." "One of her parolees?" "No." "She said she didn't recognize him." "I thought maybe she was just being paranoid." "So according to Shauna's supervisor, all of her parolees were nonviolent offenders, and none of them looked like this sketch that we took off the neighbor or match prints that CSU got from the crime scene." "So it's quite possible this had nothing to do with her job?" "Then why torture her?" "What could the killer want?" "What, Castle, no crazy theories?" "Oh, he's got bigger issues." "His daughter's moving in with a boy." "And you're letting her?" "Well, apparently the only way to stop her is locking her up, but according to miss by-the-book here, that's unlawful imprisonment." "Hey." "Caught a break on that stalker." "Couple nights ago, Shauna filed a harassment complaint." "Apparently, three days ago, a guy confronted Shauna on her way home from work." "Said the lives of half the people on the planet were at stake." "Whatever crazy theory I could have come up with, this is better." "She managed to get away and duck inside her building, but when she looked out her window, he was still out there waiting for her, so she called the cops." " Did they pick him up?" " Yeah." "He didn't have an ID and he was pretty much off his rocker, so they put him on a 72-hour psych hold." "He was released early this morning." "They were never able to ID him, but check it out." "Get over to the psych ward." "Pull his records." "We need to find out who he is." "You do not understand." "We are running out of time." "I need to get out of here." "You have to let me go!" " Why do you feel you need to go?" " Come on, I told you!" " I--she is in danger!" " Who is in danger?" "You're not even listening to me!" "Shauna Taylor!" "All I know is 12-58." "That is all they told me, okay?" "That is how is starts, and if I am not there to stop it, we are all dead!" "Do you understand me?" "Dead!" "You..." "Somebody has to let me out of here!" "All right, listen to me!" "I need to save her!" "Do you think by "save," he meant kill?" "Because it sounds to me like he really didn't want her to die." "He's mentally ill." "He may not know the difference." "12-58--what do you think that means?" "Time." "Address." "Bible verse." "Or maybe it's.." "Random numbers from a disturbed mind." "Either way, we got to find him." "The guy's a John Doe." "He's got no ID, no address." "Could be homeless." "Where do we even start?" "We'll put out a BOLO, get his info to every hospital, precinct, and psych Ward in the city." "I'll send out his pictures to shelters and soup kitchens, see if we can get lucky." "I think we just did." "That was our victim's neighbor." "He just saw our John Doe breaking back into Shauna's apartment." " NYPD!" " Show us your hands right now!" "No!" "Uhh!" "No, no, no!" "Let me go!" "You don't know what you're doing!" "We know exactly what we're doing." "Please listen to me." "Don't do this." "Please." "You have to let me go." "If you don't, a billion people will die." " Yeah?" "How they gonna die?" " I don't know." "I only know that they do." "Yeah?" "How's that?" "Because..." "I'm from the future." "This just became my favourite case." "So... future, huh?" " That's right." " Okay." "So why don't we just start with something simple, like your name?" "Why does everybody wanna know my name?" "And who cares?" "It doesn't matter." " Humor me." " Fine." "You can call me..." "Simon." "Simon..." "Doyle." "And what year are you from, exactly?" " 2035." " Castle." "Don't tell me you weren't wondering." "No, what I was actually wondering was what were you doing in Shauna Taylor's apartment?" "Same thing you were, I expect." "Looking for her killer." "Except all the evidence points to you." "Detective, it was my job to prevent her murder." "Ipso facto, QED, I am not her killer." "Point, in fact, she was never even supposed to die." "Okay?" "But because she has, a chain of events has started, that if I do not stop-- billions of people will die?" "That's exactly right." "Look..." "After the bloody energy wars of 2031, we'd finally managed to cultivate new sources of power." "Energy wars?" "Yeah, Neo-fascists come to power, try to control the world's energy supply for a select few, but don't worry." "We defeat them." "Turns out that one of these new sources of power is a tachyon generator." "It..." "Lets us open doors in the time stream continuum, allowing us to travel back in time." "But, of course, because of the possibility of abuse, it was tightly regulated and kept secret from the public." "We have a witness that saw you leaving Shauna Taylor's apartment shortly after she was killed." "I'm getting to that." "Look." "Look, I'm a temporal anthropologist." "What we do is we travel back in time and we--and we study culturally significant eras-- ancient Egypt, middle ages." "Man, I've been to Nazi Germany." "Aren't you worried about the butterfly effect?" "Accidentally changing something in the past, thus altering the future?" "No." "We're careful." "The time stream is mostly self-correcting, okay?" "Any small change is like a little ripple in a fast-moving river, right?" "It's gone in a second." "Doesn't matter." "But if someone was to do something big, if somebody was to do something massive, then, yes, of course, damn right you can change the future, and by the way, that's exactly what just happened." "Somebody broke into our lab, okay?" "Made an unauthorized jump back in time." "We don't know who." "But when they did, the numbers-- they started to spike." "Now I'm like a tide going out before a Tsunami." "And what happens when the Tsunami hits?" "Well, it hasn't caught up to us yet, okay, but when it does, whatever chain of events that has just started now will result in billions of deaths that did not otherwise occur." "You understand me?" "Okay." "Um, Mr. Doyle, let's say that you are indeed from the future..." "How did Shauna Taylor fit into all of this?" "I mean, how does her death change things so radically?" "I don't know." "All I know is that we traced the first change in the timeline to her apartment," "October 7th, 12:58 A.M." "Which is why they sent you back, why you accosted her-- to stop that first event." "And I failed, okay?" "And now she's dead." "But this is why I was searching her apartment... to find out why she was targeted, why this person would torture her." "There's a reason he came back in time to find her." "She had something he needed." "I don't know what." "Some piece of information." "Doesn't matter." "What matters is that I get out of here, okay?" "Because it is not too late." "I can still stop this." "But you have to let me go now, okay?" "I only have a few hours before they recall me." "You're gonna be delayed." "Oh, no." "Recall you?" "This is painful." "No, man." "I'm talking to people who still think the earth is flat." " Hey." " Hey." "His fingerprints are a match for the ones we pulled from the crime scene." "No question he's our guy." "Yeah." "No kidding." " You're making a huge mistake!" " Castle." "Yeah?" "For the sake of our future, please tell me you don't believe that guy." " Oh, no." "But you got to admit, it's a great story." " Really?" "Uh, thought it was kinda derivative." " Yeah, like a mash-up of "12 Monkeys" and "Terminator."" " Mm." "Yeah, but it's the way he told it...total commitment." "Commitment that turned deadly." "I mean, to maintain his delusion," "Shauna had to die." "He might not even know that he killed her." "Hey, did you guys find out what this device was" " Doyle had on him?" " Yeah." "Tech said it's just a bunch of junk thrown together." "What were you expecting, Castle?" "Time travel device?" "Doctor who's sonic screwdriver?" "You watch "Doctor Who"?" "Oh, that's Lanie." "Okay, we'll hit the morgue." "Why don't you guys time travel over to your desks and let the d.A. Know that we've got our killer?" "He's not your killer." "What do you mean?" "I mean time of death was between midnight and 2:00 A.M." "Doyle wasn't released from psychiatric hold until 4:00 A.M." "It can't be him." "No, it has to be him." "He was stalking her, and he was at the crime scene." "Yeah... hours after she was dead." "In fact, time of death is probably closer to 1:00 A.M." " How can you tell that?" " Her watch." "It stopped at 12:58, probably from one of the electric shocks." "May I?" "12:58." "Did you just get a chill?" "No, Castle, I didn't just get a chill." "Do you wanna know why?" "Because Doyle was at that crime scene, and he had plenty of time to change her watch to fit his delusional story." "And just because he wasn't there when she was being murdered, it doesn't mean he's not involved somehow." "There's something else." "Shauna was with someone the night she was killed." "Once I cleaned the blood from the body," "I saw these..." "On her neck." "Is that lipstick?" "Mm-hmm." "She was with a woman." "You guys, Shauna's stepbrother confirms she was gay, but he's sure she wasn't seeing someone." "There's nothing in her phone records that would indicate a girlfriend." "However, I did find a charge to her credit card for the night that she died." "Georgia's bar." "It's right around the corner from her apartment." "Looks like she was buying for two." "Could be our killer." "Okay, you guys get over there, see if she was seen with anyone or noticed anything out of the ordinary." "I will call the DA" "If we can't charge Doyle with murder..." "Maybe I can get him held with a departmental psych eval until we have some answers." "Yeah, Shauna was here." "Why?" "Did something happen to her?" "Was she with anyone that night?" "Yeah." "It was odd." "The chick she was hanging with was a pro." " You mean, like, a hooker?" " Yeah." "I bartend weekends down at the standish." "Chick's a regular in their lounge targeting upscale men." "You ever seen her down here before?" "Unh-unh." "I don't know if she was working or what, but she and Shauna seemed pretty cozy." "They left together." "You know her name?" "Veronica." "Go up to the standish." "She'll be hard to miss." "Your witnesses are confused." "I don't go to Georgia's." "Not my scene." "Well, we have security camera footage that shows the two of you leaving there together." "Wanna try again?" "Okay." "I left with her." "I like a little variety." "And what happened after you left the bar?" " Did you go to her place?" " How is that your business?" "Because..." "She's dead." "Killed in her apartment last night." "We found lipstick marks on her neck." "When we test 'em, whose DNA do you think we're gonna find?" "This wasn't me." "I didn't do this." "You were with her that night." "But only because I was paid to be." " By who?" " Some guy." "He hired me to come on to her." "Why?" "He wanted me to get in her place and steal her keys." "I-I didn't know he was gonna kill her." "Is this the guy?" "No." "This guy was way more intense, scary." " Who is he?" " I don't know." "I didn't want to know." "I just did what I had to and I got out of there." "If you didn't know him, why'd you agree to take the job?" "Because I had no choice." "Mick, my manager, said I had to." "He said this guy was a friend of his." "So if we are gonna find the scary guy, shouldn't we be tracking down this manager?" "Don't have to." "We had Veronica call him and tell him she's been busted for solicitation." "He thinks he's coming in to bail her out." "So... how's our Time Traveler?" "Well, he's still sticking to his story." "Keeps checking his watch, saying he's about to be recalled." "Hmm." "Well, it's not a total waste." "I did get some excellent stock tips." "Well, don't invest just yet." "Once we find out who hired Veronica, then we'll know how Doyle's involved." "Detective Beckett?" "Dr. Silverman, here for psych eval on Simon Doyle." "He's right back there." "Right back where?" "Where is he?" "Where did he go?" "Not where." "When." "I'm just saying, what if he was telling the truth and he really was recalled back to the future?" "He wasn't recalled back to the future." "And do you know how I know that?" "Because he's not a Time Traveler." "Okay." "So where is he?" "Simple explanation?" "There was a mix-up with the paperwork when his charges were dropped, and some desk monkey accidentally let him go, and now they are all trying to cover their asses." "That's reasonable." "It's unlikely, but it's reasonable." "Yo, any luck finding Doyle?" "No." "Not yet." "Hmm." "Is that Veronica's manager?" "Yeah." "Mick Linden." "Just came in." "We're about to lower the boom." "You need a hand?" "Nah." "We got it." "Wouldn't want you to lose him, too." "Here's your situation, Mick." "Your girl Veronica says she stole the victim's keys for a friend of yours." "That makes you an accessory." "Oh, man, I swear to God" "I-I didn't know he was gonna do this." "Yeah, well, good luck getting a jury to buy that." "You're looking at a lot of time, Mr. Linden." "Come on, man." "Hey, man, I just got out six months ago." "I'll tell you what." "You tell us everything about that murderous friend of yours, and we'll tell the DA what a swell guy you are." "His name's Ward." "Garrett Ward." "Oh, my God." "He was my cellie at Five Points." "Where can we find him?" "I don't know, man." "He found me last week." "Said he'd just gotten out, he needed a favor." "I figured it was better to do it than end up on his hate list." "You're afraid of him." "Hell, yeah." "Everyone was." "I mean, this guy was inside a week, he was running the cell block." "Guy is ice-cold." "What else do you know about him?" "Nothing, man." "And I shared air with this guy for years." "Never once did he talk about his family, his hometown, his girl." "But he might have been a soldier." "Yeah, why's that?" "'Cause he had that way." "Haunted." "Always doing push-ups." "Always on alert." "You know any reason why he'd target Shauna Taylor?" "He never even mentioned the name." "And... you said before, she wasn't his parole officer, so I have no idea." "Could he have taken her out as a favor to a friend?" "That guy didn't have friends." "But, uh." "Like, sometimes he'd talk about his mission." "What mission?" "Alls he'd say is he had unfinished business, and it would change everything." "Garrett Ward." "Till six years ago, no criminal record." "In fact, until six years ago, no record at all." "No DMV, no military, nothing." "That's impossible." "Unless he's the other Time Traveler that Doyle was talking about." "Whoever he is, his record begins when he was arrested for bringing a backpack bomb into a global energy conference here in Manhattan." " And what was his motive?" " Well, at the time, the authorities linked him to a radical eco group that was protesting the conference." "According to his file, he's some kind of anti-science nut job." "They found lots of unabomber-style notebooks on him decrying "the destruction of the rightful kingdom of God by science and technology."" " What's his connection to Doyle?" " Nada." "What do you mean, Nada?" "Guys, come on, it's so obvious!" "Look." "Ward is the guy that Doyle was sent back in time to stop, okay?" "Ward was sent back in time on some history-altering mission that he failed to accomplish, ending up in prison." "Six years later, he's trying to complete that mission, which is why Doyle has been sent back to now, because now is when the timeline changed." "Well, I was thinking that maybe" "Ward and Doyle knew each other in the non-crazy world, like perhaps that Eco group that Ward was supposedly a part of." "Okay." "Not as fun." "But why would an anti-science nut torture and murder a parole officer?" "I mean, what's her connection to any of this?" "We still haven't found one." "Why don't you guys go back in time and see if you can dig up any of Ward's known associates from six years ago?" "Castle and I will look into his case record, see if we can find a connection between him and Shauna Taylor or perhaps figure out what his unfinished business was." "No, Alexis, I do trust you." "I'm just saying, deciding to share an apartment with someone you met on a banana plantation a month ago just doesn't strike me as the smartest decision you've ever made." "Alexis, you..." "Alexis..." "She hung up on me." "Hmm?" "Maybe I shouldn't have said that stuff about the bananas." "Um..." "You know, Castle, maybe this is a good thing for her." "I mean, she sees us, and she sees you starting something new." "Maybe she's just trying to figure out how she fits in." "You're saying this is about us?" "No." "Um, I'm saying this is about her." "It's--it's about her growing up." "You know what I'd do if I had a time machine?" "Mm?" "I'd go back to..." "Relive all those moments." "You know, holding her tiny hand, putting her up on my shoulders." "Just..." "I can't believe those times are gone." "I know, Castle, but think about all of the great times that you have to look forward to in her future a-and in ours." "Yeah, assuming there is a future." "If Doyle's right, there may not even be one." "oh, come on, Castle." " Whoa." "Look at this." "It's an article on the attempted bombing." "Look at the picture." "That's Malcolm Wickfield, Shauna's stepbrother." "He was at the conference?" "He wasn't just at the conference." "He was one of the speakers." "Wickfield's address was unlisted." "You had to get it from central." "That's what Ward wanted from Shauna?" "To find her stepbrother?" "He's going after Wickfield." "NYPD Homicide." "What happened?" "Wife said some guy just showed up at the door and attacked him." "He beat the hell out of him then broke his neck." "Yes." "That's him." "So what happened?" "We were, uh, doing a crossword puzzle together, and... the doorbell rang and when Malcolm answered it, that man, he... he grabbed him by the neck and he dragged him into the living room" "and he...he kept yelling, "Where's the child?" "H-how can I find the child?"" " What child?" " We didn't know." "We told him we didn't know." "We don't have any children." "I called 9-1-1, and when he heard the sirens, that's when he..." "He killed Malcolm." "He--he ran out before they arrived." "Mrs. Wickfield, what exactly did your husband do?" "He was a theoretical physicist." "He was trying to isolate new energy sources." "Why would anyone target him for that?" "Because some people thought that his-- his experiments were dangerous, that somehow he was gonna..." "Create a black hole that was gonna swallow the earth." "Of course, it was-- it was all nonsense." "Well, the work is very exciting." "But right now it's all theoretical." "What our research really offers is an entirely new way of looking at the universe." "Changing the way people see the universe?" "That's exactly the kind of person whose death could alter the future." "It's also the kind of person that a crazy anti-science nut like Ward would fixate on." "Which means any of the other speakers at that conference could be next." "Except now he's looking for a child." "Okay, contact the conference organizers." "Get names of everyone that attended." "Let's see if there are any children on that list." "This guy's gonna kill again, and we don't know anything about him." "I may have found someone who does." "That eco group that Ward was supposedly a part of?" "Well, it's since disbanded, but its leader at the time was a guy named Jack Hastings." "He's an environmental author now, and his new book, "Our Earth's End", it's about the coming Eco disasters and the destruction of the human race." "If you want to know the future, look at the facts." "In less than 35 years, we'll have no gas, no coal and no uranium," "as our energy resources dwindle and needs rise due to global warming, scarcity will spark the inevitable-- a massive, bloody world war," " probably within the next 20 years..." " Massive, bloody energy wars?" "Just like Doyle described." "Given how compromised our planet already is, will the human race survive?" "Thank you." "Yeah, I knew Garrett Ward." "When he first came to us, he said all the right things-- how big oil and coal were destroying our environment." "He even helped me plan that sit-in on the energy conference." "After a few weeks, it became obvious he didn't care about the environment." "When he was caught with that bomb, we realized why." "He was using you to get into the conference." "So how well did you know him personally?" "Well, enough to know he was nuts." "How so?" "He was... paranoid." "He was always looking over his shoulder." "And he'd say things about the future, messed-up things about apocalyptic wars and how the human race needed to be cleansed." "It was pretty creepy." "Kind of like some of the predictions you just made?" "No." "This was different." "Ward talked about it like it was real, like it had already happened." "Did he ever say anything to you about a child?" "Not that I recall." "What about this guy?" "You recognize him?" "Sorry." "Do you know if there was anyone that he was close to, anyone who would know how to find him?" "He burned every bridge he had when he walked in with that bomb." "But if you're looking for him," "I'd try the east river power plant." "That's where he was living six years ago." "He said, uh, the electromagnetic field made it harder for the government to find him." "I told you, the guy was crazy." "This place shut down in 2010." "You really think he'd come back here?" "You can stay in the car if you're too scared." "Alone?" "At an abandoned power plant?" "No, thank you." "Maybe we should put something in our vows about following each other into creepy places." "Look, I'm just saying-- energy wars, a soldier from the future-- everything seems to support Doyle's story." "Aren't you weirded out by all this?" "Why would I be weirded out?" "Ward's just another paranoid schizophrenic, no different than Ted Kaczynski or Mark David Chapman." "Then how do you explain Doyle?" "Well, probably another crazy who got caught up in his delusion." "He and Ward must know each other somehow." "Castle." "Someone's been here." "Don't...don't... it's him." "Come on." " Where are you going?" " Call for backup." "Good idea." "Hey." "Damn it." "Beckett?" "Hey." "Hey." "Oh." "Ow!" "I'm okay." "How'd you find us?" "I didn't." "I was tracking Ward." "You said you didn't know him, but he recognized you." "Well, no, he recognized this, okay?" "This is a Tracking Beacon." " A what?" " All I have to do is touch him with it," " and our scientists can pull him right back." " Drop your weapon." "Hands in the air." "Okay." "Easy." "Okay." "Detective, the gun is really not necessary." "The hell it isn't." "How did you get out of holding?" "And how are you involved?" "You know how." "You just don't want to believe me, but trust me, detective, we're on the same side." "You do realize I just saved your life, right?" "Yeah, this is detective Beckett." "I've got a suspect at large." "I'm gonna need patrol sweeps of the area along with a full C.S.U. Team at the scene." "Real charmer, that one." "I can't believe you marry her." " How did you know I marry her?" " One of your book jackets." "You know, "Richard Castle lives in New York with his wife, senator Beckett, and their three children."" " Senator?" " Three kids?" "Yeah." "Yeah, yeah." "It was kind of hard for me to believe myself, given all the crazy stuff" " that goes on between you along the way." " Crazy stuff?" "What stuff?" "Are you kidding me?" "She..." "I'll call you back." "No, I shouldn't say." "I shouldn't say." "I can tell you, thought, that I'm really glad you stopped writing those stupid mystery books, okay?" "Because your serious literature is so much better." "I write serious literature?" "Beckett, you hear that?" "Yeah, I heard." "And I'm the president of fantasyland." "No, it was--it was senator, actually." "It was... senator, but not if Ward changes the future, do you understand me?" "Yeah, but didn't the time stream already change with Wickfield's murder?" "No, no, Wickfield's death was a...was a minor disruption." "But all the work he was doing..." "Never amounted to anything." "Nah, he wound up a footnote in history." "According to our calculations, the big event, whatever it is, it hasn't happened yet." " Then why was Ward after him?" " I don't know." "You--you said he was looking for a child, right?" " Well, he had..." " Castle!" "He's our suspect." "Could you please not discuss details of our case with him?" "Maybe you could come over here and help me look through this stuff." "We might find a clue..." "As to who Ward's next victim's gonna be." "For your information," "I wasn't sharing details of the case." "I was playing into his delusion to see what he knew." "Look at this." "This is a photograph of an old letter addressed to Malcolm Wickfield." "It's dated six years ago." "Looks like it's from a High School student asking to see him speak at that energy conference." "Why would Ward have this?" "I don't know." "It's only the first page, but there's no name or signature." "But look at the words Ward circled." ""Brooklyn," "P.S 311," "state award last year for my physics project."" "Each one's a clue as to the letter writer's identity." "Ward must have been after him." "Do you think this is the child that Ward is looking for?" "Mr. Doyle..." "Do you know who he is?" "No, no, I've never seen him before." "But if Ward's targeting him, there must be a reason." "Why would Ward be after a high school student?" "I don't know." "But we gotta find him first." "Yeah, but no name, and only these clues to go on?" "It could take days." "Hey, could I make a suggestion?" "Ward, you know, he was working off of a photo of the letter, right?" "So perhaps the easier path is to ask, where's the original?" "It's bound to have the kid's name and address." "A letter from six years ago." "Good thing most geniuses are pack rats." "I kept trying to get him to throw some of this stuff out, but he never would." "Uh, let me see that picture again." " Oh, yeah." " You sure you've never seen the kid before?" "No, but, uh, Malcolm was very encouraging to students, so it's a possibility that he knew him." "Wait a minute." "Here." " That's it." "It's written by some kid named Paul Deschile." "Wait a second." "No." "That's not "De-shiel." Um..." "It's "Duh-child."" "He wasn't looking for "the child,"" "he was looking for Deschile." "Who the hell's Paul Deschile?" "He's a 21-year-old student at Hudson getting his post-doc in theoretical physics." "All right, get him into protective custody." "He's on leave this semester." "The university has no idea where he is." "Still trying to look for his parents," " but they moved out of state a few years ago." " Detective, it's him!" " Deschile." " You know him?" "Of course I know him." "Everyone knows him." "Oh, man, if..." "if he's killed..." "Okay, I'll call you back." "Doyle, sit down." "No wonder billions of people die." "Okay, who the hell is Paul Deschile?" "The energy wars, all right?" "I told you about the other side." "A group of fascists-- they were worse than the Nazis." "Th-they were slaughtering people by the tens of thousands, okay?" "They were winning." "Until Deschile...he and his team, they created an energy shield." "Okay?" "It was able to stop their weapons and completely turn the tide." "Detective, listen to me!" "Ward is still obviously fighting for the fascists!" "They're trying to win the war by rewriting history!" "And if he kills Deschile, there will be no energy shield!" "And without that energy shield, we lose that war!" "Ward's gonna kill Deschile, and that is why billions of people die!" "Okay, you know what?" "We don't have time for this." " Take him to holding, please." " Fine, we don't have time." "You're correct, okay?" "Forget everything I said!" "Forget about Time Travel!" "Forget about wars!" "None of that matters!" "All that matters is Deschile!" "You understand me?" "You keep him alive!" "He cannot die!" "No." "Deschile." "Yeah." "Paul Deschile." "No, wait, please don't..." "don't put me on hold." " Anything?" " Esposito got ahold of his parents in Oregon." "They think he's staying with a friend in the city, which is who I'm holding for now." "You don't think any of this could possibly be real, do you?" "I don't know, Castle, but I have no intention of letting this kid die." "Yes." "Hi." "This is detective Kate Beckett, NYPD" "I'm trying to get ahold of a Paul Deschile." "Where?" "He's at the Planetarium." "Wait, just like you told what other guy?" "Who else did you tell?" "Ward knows." "Planetarium's all the way uptown." "We'll never get there in time." "The cosmos is vast and glorious... more wondrous than we can fathom." "It takes our breath away and ignites our imagination." "It is the essence of time itself-- the past, the present, and the future." "It's an enigma seemingly impossible to grasp, and yet we pursue its mysteries." "We dare to reach out to understand swirling galaxies, exploding stars..." "Freeze!" " Don't even think about it!" " NYPD!" "Let me see your hands right now!" "Knife!" "You okay, kid?" "Why Wickfield?" "Why Deschile?" "What were you hoping to accomplish?" "Who is that man?" "You ran from him at the power plant." "Why?" "Mr. Ward, there is no record of you before 2007." "Where are you from?" "Okay, Ward." "Whatever you thought you were doing..." "It's over." "What'd he say?" " Nothing." " No apocalyptic visions, no nightmarish warnings of dire things to come?" "Whatever delusions he has in his head, he is keeping them to himself." "Well, if nothing Doyle said was true, why else would Ward target Deschile?" "I think we can answer that." "I'm the one who alerted security to Ward's behavior at the energy conference six years ago." "They stopped him because of me." "It looks like this was all just about revenge." "I'm just sorry it cost Dr. Wickfield his life." "You know, the talk he gave at that conference rocked my world, and if it wasn't for him," "I'd probably be doing something completely different with my life." "Come on, man." "I'll walk you out." "So, there is a simple explanation after all." "Yes." "Now we know why Ward tried to bomb that conference-- to kill Deschile." "You see, in the future, when the famous Deschile will give interviews, he'll say that's where it all started." "Consequently, Ward will know exactly where... and when...to find him." "You're trying to drive me crazy, aren't you?" "Well, apparently I already do, if we end up with three kids." "Would you like to know their names?" " Yes." " No!" "Doyle?" "What are you doing out?" "Well, you said that I had the right to an attorney, and he said that you couldn't keep me anymore." " What about your psych eval?" " Oh, please." "Are you kidding me?" "I passed that with flying colors." "But you should have heard the crazy stuff coming out of my mouth." "Growing up in Denver, middle-class family." "I mean, I haven't lied that much in years." " But I..." " Now, now, detective, don't be upset." "Because of you, billions of people are alive." "Because of you, future generations are safe." "I don't care what you say, Doyle." "There's a connection between you and Ward, and it has nothing to do with Time Travel." "And I'm gonna find out what it is." "Okay." "Good luck." "Because before yesterday, I had never even met Ward." "That's not entirely true." "I went back through Ward's incarceration file." "Before his trial, he spent two weeks in a psychiatric ward being evaluated by the state." "In the next room was another patient, a John Doe." "I had them pull his photo." "And there's the connection." "No, no, no." "That..." "that's...that's ridiculous." "Because I have never, ever..." "Oh, wow, that's really clever." "What?" "What's clever?" "That's me." "Right?" "But I-I haven't done it yet." "Don't you see?" "Now that they know who Ward is and where he's gonna be..." "They're gonna send me back to make contact with him, find out who he works for, if they're planning anything else." "It's perfect." "Oh, wow." "Uh, I don't have much time left." "Um..." "I don't know." "See you in 20 years." "Is it--is it just me, or does that make sense?" "No, it's just you." "Ooh, he forgot his little doohickey there." "Hey." "So what happened?" "Um..." "Missed him." "Well..." "You know what?" "After a case like this one, I think a warm and cozy bath is in my future." "Talk to you tonight?" "Sounds good." "Jeez." "You're really doing this?" "I am." "I know what you're thinking." "You're thinking I'm making a huge mistake." "What if you are?" "This isn't something you can just go back and undo." "Why don't you wait a year, okay?" "Move into the dorms." "I'm sure Pi can take care of himself." "And if after a year you still want to move in together," "I won't say a word." "Yes, you will." "I don't know how this is gonna turn out, dad." "None of us do." "But it's my life, my future." "I have to find out for myself." "Who are you always saying is the smart one in the family?" "You." "Dad, I know what I'm doing." "It'll be okay." "Too soon."
