"You got me!" "I give up." "Oh, boy, oh, boy!" "She's finally here!" "Hello." "I'm your new home-operating system." "My name is Lucy." "What's yours?" "Uh, my name is Rick Castle, and..." "And... my wife just left me." "Yikes." "Sucks to be you, Rick." "Can't you hit any harder than that?" "Oh!" "Oh." "I'll take that as a yes." "Come on." "Listen." "You can still back out." " I can do this on my own." " Not a chance." "I'd be dead if not for you, which means I owe you." "Besides, I always wanted to be a digital investigator for the NYPD." "It's a real job, Vikram." "You'll be helping the 12th solve homicides." "By day." "By night, I'll wear a cape and track down the mysterious villain who sent a hit squad to kill us and scapegoat-murdered Allison Hyde." "Would you take this seriously, please?" "I just blew up my marriage to go down this path." "I'm sorry." "Hell, I should be giving you the chance to back out." "No." "If I don't get justice for Rachel and for everyone else, no one will." "We just got to do this fast." "Fast is the one speed we can't move." "We need stealth." "If this takes any longer, then Castle is gonna figure out what we're doing." "And if he does?" "He's gonna step in, and he's gonna put himself in danger." "Then make sure he stays away." "Has Beckett told you anything about the breakup yet?" "Not a word." "You talked to Castle about it?" "No." "And I've left him a bunch of messages." "Shakes your faith." "I guess nothing in life is permanent." "Tell that to the victim." "Oh, hey." "Captain Beckett." "What brings you out into the field?" "Work." "What, do you think I'm gonna be stuck in the office" " just 'cause I'm captain?" " We..." " so, who's our fugitive?" " No I.D. yet." "But the jumpsuit is standard issue at Rikers." "But they say that none of their prisoners have gone missing." "We had them lock down the facility, but a 14,000-inmate head count is gonna take some time." " You run his prints?" " Yeah." "So far, nothing." "Nothing?" "The guy's a convicted felon." "His fingerprints are on file." "Probably a glitch." "You know, those portable scanners..." " sometimes they're wonky." " Yeah." "Is there any chance that this wasn't a homicide?" "None." "It took brute force to puncture the victim's body with that branch." "Someone had to shove him onto it." "So how does an escaped convict from Rikers Island end up in the middle of Central Park without anyone seeing him?" "It was late." "Lividity puts the time of death between midnight and 2:00 A.M." "All right, keep running prints." "I'm gonna walk around and see what I can find." "Hey." "You didn't call me back." "Yeah, I'm..." "I'm sorry about that." "Oh, that's okay." "But are you okay?" "I'm fine." "I'm just a-a little lost and taking some space so I can figure things out." "I just hope that I haven't hurt him too much." "Girl, please." "Castle is a grown-ass man, and he knows that you love him very much." "I'm sure he's okay." "I just don't know what to do, Lucy." "I've compiled a list of top-ranked divorce attorneys." "No!" "I don't want a divorce." "I want my wife back." "How do I do that?" "I don't know." "How did you get her in the first place, Rick?" "Has Beckett talked to you?" "Give us a minute." "You know better than to think I would betray her confidence." "Damn it, Lanie, tell me... why is Beckett keeping me in the dark?" "The man who went Houdini for two months last year?" "Whoa." "I didn't Houdini." "I was houdinied." "Doesn't matter." "When you came back, she accepted you without question, so you can damn well give her some space now." "I can't lose her." "I know." "Is that from the 12th?" "Castle." "Escaped prisoner." "Young... maybe 21, 22?" "Is that..." "Iron fence?" " Tree branch." " Ouch." "Got an I.D. yet?" "I'm not telling you." "I've seen this devil before." "Just stop." "Working murders is not your job anymore." "He's gonna be an absolute wreck." "And it's our job not to let him spin out." "That's what the C.D.R.K. is for." " "Castle depression rescue kit."" " Mmhmm." "Video games, sumatran civet coffee beans, enhanced blu-rays of the original "Twilight Zone," and..." " this." " 9-woof-woof?" "Mm-hmm." "Puppies at your doorstep in 30 minutes or less." " Ah." " Puppies." "Good morning, my lovelies." "Isn't it great to be alive?" "Richard, are you feeling okay?" "Never better." "Because I know how to win Beckett back." "Is she wanting to be won back?" "When we first met, it was my roguish charm that caused Beckett to drop her guard, but it was my sherlockian skills that made her fall in love with me." "I just have to solve a few cases with her to show her that, together, we are still magic." "Richard, you do know that you cannot just barge your way into the precinct and talk your way onto a case anymore." "I am a licensed private investigator." "I don't need a precinct to solve a case." "Now, this tattoo was on the body of a dead convict found in Central Park." "I know I've seen it somewhere before." "I just don't know where." "I do." "Hey." "Um, Rikers completed their head count." "All inmates are accounted for." "So, where'd the Vic's jumpsuit come from?" "A costume shop." "Our John Doe was not an inmate." "He was a college student." "Tattoo on his shoulder is the original mascot design of the Hudson U. Red Devils." "Now, I checked the college website." "Peter Garber." "21 years old, majoring in marketing." "But that doesn't explain the jumpsuit." "You guys, it's October." "Halloween's basically a month-long party in college." "Ah, the hallowed halls of academia." "I remember them well." "More like the hallowed halls of crackheads in my schools." "Head over to Peter's frat house." "Interview his roommates." "I'm gonna break the bad news to the Dean." " Right." " Okay." "Hi." "I'm Captain Beckett." "I need to speak with Dean Feller, please." "It will be nice to have a best-selling author on the faculty." "Oh." "Welcome to the Hudson family, Mr. Castle." "Oh, please, Dean Feller, call me "Professor Castle."" "Oh." "Captain Beckett." "Fancy seeing you here." "S08E03 PhDead" "Castle, I know what you're doing." "I'm giving back to the community by molding young minds?" "You're not joining this case." " Aren't you two married?" " Yes, we are." "Dean Feller, meet captain Beckett of the 12th precinct." "Yes." "And husband and wife need a moment in private." "Whoa, whoa, hang on." "Whoa, whoa, whoa." "Ah." "It took me an hour to tie this." "Oh, you saw the tattoo at the morgue, didn't you?" "I saw Lanie at the morgue." "I can't recall if I saw other things on bodies with gruesome chest wounds." "Let me ask you... how large of a donation check did you write in order to become a professor?" "Guest professor." "Look..." "I have no desire to interfere with your case, but I can't help it if my path crosses with yours while I'm teaching here." "Castle, I asked for time." "Why can't you give me that?" "Because you need me." "I..." "I can't do this right now." " Kate." " I'm sorry to interrupt, but I really need to know why there are police on my campus." "A student of yours, Peter Garber, was found murdered in Central Park last night." "That's awful." "He was a wonderful young man..." "a model student." "He won this year's fellowship award." "Well, I'll need access to all of his files, as well as a discreet room to interview his teachers and friends." "Of course." "And as for you..." "Professor, this is a police investigation." "Stay out of it." "She's such a kidder." "We got something." "What's wrong?" "Castle's here." "He bought himself a PhD to get in on this case." "You guys are not to work with him in any way." "Is that understood?" " Yeah." " Yes." "Absolutely." " Okay, so, what do we got?" " A suspect." "Yeah?" "Peter was pledge master at the beta omega rho fraternity house." "Let me guess... he hazed someone and they threatened revenge?" "The opposite, actually." "Scott Powell." "Former beta omega." "Scott terrorized a group of pledges, got one of them sent to the hospital." "So Peter turned Scott in, got him booted from the frat." "Okay, well, that sounds like motive." "Let's bring him in for questioning." "Yeah, that might not be the right approach." "Scott's dad is a defense attorney." "When the university tried to expel Scott, daddy threatened to sue." "So Scott's not gonna talk to us." "Unless we can get him to talk without him realizing that he's talking?" "How do you plan on doing that?" "So, how's the talent in your marketing class?" "Oh, solid." "Especially this hot blonde named Jenny." " Aw, for real?" " Yeah." "Hey, did you see that that frat boy got murdered last night in the park?" "Aw, yeah." "I heard he got impaled." "Ah, was it Peter, uh..." "Something." "What house was he in?" "I have no idea." "Hey, bro, you know what frat the dead dude's from?" "No, officer, I sure don't." "What?" "We ain't cops, man." "Dude, you look like you're 40." "Bitch, please." "I got carded last week." "Yeah, for your AARP card." "And your partner's growing ear hair in front of my eyes." "All right, funny man." "We heard that you had a hate-on for Peter Garber." "So you want to tell us where you were last night?" "No." "But you can call my lawyer." "He's gonna get a real kick out of you guys." "Have a nice day." "Oh, and remember..." "fiber's your friend." "I don't really have old-man ear hair, do I?" "Guys." "You didn't really think you could "jump street" the prime suspect, did you?" "Castle, what are you doing here?" "I heard about the Scott Powell hazing incident." "I thought I'd offer the NYPD my P.I. services." "No, thanks." " Free of charge." " No, thanks." "All right, fine." "I guess I'll just use my newfound faculty privileges to talk to Scott on my own." "He's got a contemporary-lit class in 30 minutes." "They have a very special guest speaker... a certain ruggedly handsome best-selling author." "He just might be the angle we need to get this guy Scott to talk." "Beckett gave us a direct order." "Will she be more upset when she finds out Castle solved this case before us, or when she finds out we've been cooperating with him?" "Perhaps my secret weapon is the loophole you're looking for." "What secret weapon?" "Anybody sitting there?" "Uh, you are." " Thanks." " Yeah." "Uh, I'm Scott." "Clara." "So, you know anything about this Richard Castle guy?" "A little." "He's an irreverent crime novelist with a carefree spirit and a hatred of exclamation marks." "Or so I hear." "Hmm." "Well, I saw an interview with him a few years ago." "He was trying way too hard to be cool." "I'm sure he's mellowed with age." ""To die, to sleep..." "To sleep, perchance to dream."" "Or not." ""Aye, for there's the rub." "For in this sleep of death, what dreams may come?"" "William Shakespeare, the bard." "A man as intimate with violence and murder as any in history." "Who can tell me the classic motivations for murder?" "You, in the printed non-ironic tee beside the too-friendly blonde." " Oh, me?" " Yes." "What might drive a person to murder?" "I don't know." "Revenge?" "Revenge." "A man wronged, his reputation besmirched, so he strikes out in passion." "Some might consider his actions justified." "What else might drive a person to kill?" "Being forced to read one of your books?" "Though that's probably more of a motive for suicide." "And, uh, what was the last book you read..." ""Zen and the art of hazing hipsters"?" "Oh, I love how you come in here quoting Shakespeare like it's just gonna magically elevate that treadmill fiction you write." "Treadmill fi..." "Get out." "Now." "Works for me." "Are you okay?" "What the hell?" "First the cops try and front me, and then that clown." "Cops?" "A guy from my old frat got killed last night." "Peter Garber." "They think I hated him 'cause he got me kicked out for hazing some newbies." "But I spent the last semester trying to make amends." " With Peter?" " Yeah." "Told him I was sorry, you know, and he said we were cool." "He even asked me for a favor." "Said he needed a quiet place to study away from the frat house." "I work at residential housing, so I hooked him up with an empty apartment on the D.L." "Why didn't you tell the cops?" "My dad's a lawyer, and he taught me you never trust the police." "Actually, you know, he also taught me that blondes are more fun." "What say we go out later?" "My crew and I found this great bar last night called Jinx." "I'd love to, but I'm actually getting fitted for an iron lung in the morning." "Bye." "Okay, Vikram." "What have you got?" "I might have identified Allison Hyde's killer." "Pulled footage from the hotel cameras around the time Hyde was killed." "Managed to I.D. everyone, except this guy." "Look, this doesn't mean anything." "There's plenty of people who aren't in our facial-recognition database." "Didn't just use ours." "I snuck into the NSA, ran him through their top-secret database." "It's a civil-liberties nightmare, but very comprehensive." "Our well-dressed man is a total ghost." "So unless you know a ghostbuster, we're out of luck." "I-I might know somebody." "He's helped me out in the past, and he's connected to this world." "But he's technically dead, which means you're gonna have to dig him up." "Just to be clear, you mean he faked his own death and now he's hiding under a new identity that you need me to uncover?" "Yeah." "Good. 'Cause I'm not a huge fan of shoveling." "What are the odds Peter really wanted this apartment for studying?" "I'd say those odds are less than zero." "NYPD." "I thought Peter was majoring in marketing, not medieval torture." "This stuff isn't for torture." "It's a BDSM dungeon." "What?" "I read "Fifty Shades," and clearly so had Peter." "Okay." "I'm thinking this is a little less "Fifty Shades"" "and a little more "Fatal Attraction."" "So, Peter and his bondage-curious lover set up shop here to fulfill all their fantasies." "Mm." "Role play." "Perhaps kinky convict and wicked warden." "D..." "Anyway, Peter tries to break it off." "The lover, spurned, flies into a murderous rage, and then impales him in the park." "All right." "We need to figure out who Peter's been..." "Entertaining here." "That means we need to start knocking on some doors," " pulling surveillance footage." " There's an easier way." "Frat boys love to kiss and tell." "If anyone knows who Peter was involved with, it will be his brothers." "Yeah, but they weren't exactly forthcoming" " when we interviewed them earlier." " Yeah." "That's because you're "the man."" "But I'm not." "I'm in." "She's in." "We heard." "You know this isn't her first frat party, Castle." "You trying to make me feel better?" "You know, it's understandable if you're feeling a little overprotective right now with what's been happening with Beckett." ""What's happening" is I'm getting her back." "Are you sure this is the right way to do it?" "She was pretty clear that she did not want you working this case." "Working cases together is why she fell in love with me." "That's why I'm going to do whatever it takes to solve this case." "Including sending your daughter into a house full of drunken frat boys, dressed like a slutty angel?" "Open it." "Open it." "It's so sad about Peter." "Were you close with him?" "Mmmmmmm." "He was a hottie." "I bet he had a lot of girlfriends, huh?" "Mmmmmmm." "Mmmmmmm." "Hey, hey, hey." " Her eyes are up here." " What are you doing?" " I got this." " Do you?" "'Cause I'm hearing a whole lot of flirting and zero fact-finding on who Peter was dating." "Hey, bro." "I saw her first." "Get your own girl." " Ew." " Ew." "I mean it." "Hit the road, old man." "Old man?" "This old man is gonna kick your ass." "At beer pong." "Beer-pong challenge, everyone!" "What exactly is your strategy?" "To get any man to confide in you, you must first earn his respect." "To do that, I need to bro down." "Thank you." "All right." "Oh!" "Mmm." "Oh." "10 bucks on Castle." "You're on." "Hey, Captain." "What are you doing here?" " Surveillance." " Canvassing." " Surveillance." " Canvassing." "In your face, Frankenstein." "We can explain." "I ask one thing of you guys." "Whoo!" "All right, all right." "Whoo!" "Whoo!" "Mmm." "Terrible thing about Peter." "Wish I would have gotten to know him better." "You, uh, spoken to Julie?" "She must be devastated." "Who's Julie?" "Isn't that Peter's girlfriend's name?" "Peter was all about this cougar professor," "Dr. Lillstrom." "He spent all of his free time with her, if you know what I mean." "Oh, someone didn't skip his lesson on subtext." "All right, last shot, professor." "Bring it." "Thank you." "Oops." "Drink." "All right." "Party's over." "Unless you want me to start checking I.D.s." "That was a nice shot." "We should team up." "We could pong hustle." "Castle, go home." "You're drunk." "I'm not drunk." "I'm casing the crack." "Crack... crack..." "Cracking the case." "You're a lightweight." "Come on, dad." "Time to go." "Okay, angel." "You're driving." "You're pretty hot for a cop." " I have a gun." " Right." " Beckett." " It's Vikram." "I found your dead guy resurrected in New Jersey." "And I know where you can find him." "It's been a long time." "What the hell are you doing here?" "Sorry to shake your snow globe, but you helped me once when I was being framed for Vulcan Simmons's murder, and I need your help again." "Forget it." "I paid all my debts." "This man killed an assistant A.G." "Connected to Bracken's dirty-money scheme." "I don't know him." "He works for Bracken's partner, some mystery man or woman deep inside the CIA." "Why can't you just leave this alone?" "I wasn't built that way." "Look, I've got a good thing here." "A woman who loves me, a new life." "I'm happy." "You could be, too." "You just have to let it go." "I can't." "What makes you think the drug shipments stopped with Vulcan Simmons's death?" "Every narcotic has a signature, a fingerprint, if you will." "You find his, you pick up the trail." " Thank you." " Don't." "You're gonna get yourself killed." "Come on, boy." "Unh." "Oh." "You're getting too old for drinking games, kiddo." "It was for the case." "The one that Katherine keeps throwing you off of?" "I didn't win her love overnight the first time." "I'm making progress, huh?" "Hey." "Where are we on Peter's faculty girlfriend?" "Dr. Barbara Lillstrom, head of the psych department at Hudson U." "Top of her class at Harvard med school." "She was advising Peter's senior thesis." "And they had an illicit student-faculty relationship, one that ended ugly once he rejected her." "Yeah, I'm betting Peter was expecting a bad grade, not impalement." "I contacted the psych department." "Lillstrom's been out all week." "She could be on the run." "If she is, she didn't run far." "Or at least her phone didn't." "Her cell signal went dead yesterday, but it last pinged off a tower outside of a tenantless building here." "That's four blocks away from where Peter was killed." "You know, if you want to curry favor with Katherine after last night's little debacle, you might tell her about this." "No, first, we'll confirm Lillstrom is there." "Then we'll call in the cavalry." "Times like this, I wish you were more comfortable carrying a gun on your person, not just in your desk." "A good P.I. relies on his wits first, bullets second." "After your wits." "What was that?" "This explains Peter's prison jumpsuit." " Don't move." " Easy there, fella." "Unless you're a New York yankee, quit trying to steal second base." "Watch your mouth." "I'm just saying, buy me a drink first." "Take this." "Here, open 4." "No." "What?" "Are you sure about this?" "I have to warn the warden." "What kind of prison is this?" "Take a look around." "You notice any similarities..." "Between the guards and the inmates?" " Wait... they're all my age." " Exactly." "And I'm betting they're all Hudson University students." "They're doing a re-enactment of the Stanford Prison experiment." "That thing from the '70s where they studied the psychological effects of making students pretend to be prisoners and guards?" "Makes sense." "Dr. Lillstrom is head of the psych department." "Who else is gonna have the kind of pull to put something like this together?" "Maybe Peter shawshanked his way out of here." "Peter?" "He actually escaped?" "You know Peter?" "He was in your cell, but one day we woke up and he was just gone." " What did the guards say?" " They freaked." "How'd he get out of his cell?" "But we... we didn't know if they were just messing with our heads, 'cause that's what they do here." "Did you volunteer for this?" "I needed the money, but now I just want to go home." "Wait a minute." "Y-you mean, there's no panic button?" "There's no safety mechanism if you want to quit?" "There was a white flag, but they removed it when Peter was demoted." "Peter was a guard before he was an inmate?" "Head guard, recruited by Warden Lillstrom." "But he was nice to us." "I think that's why Lillstrom turned on him." "She made Peter an inmate, forced him to sit in the chair." "What chair are we talking about?" "Our daily interrogations." "We're strapped to a chair." "Lillstrom flashes images in our eyes over and over." "All these strange lights." "What does Lillstrom want to know?" "Our secrets." "The darker, the better." "It's like she's sliding around your brain, peeking into your soul." "Hey." "Come open this cell." "I give the orders here, inmate." "And I give the grades." "You saw my faculty I.D." "So, here's the pop quiz." "Failure to open this cell will cause an oh-so-disastrous end to your academic career... true or false?" "Hey." "Hers too." "Take us to Dr. Lillstrom right now." "Warden." "We, um, have a problem." "Damn right we do... years of planning, of research, ruined!" "Do you have any idea of the damage you've caused?" "Ask me if I care." "We're here investigating Peter's murder." "Peter's dead?" "Look, he broke out." "That's not my responsibility." "New York's a dangerous town." "We know all about your relationship with Peter." "I'm the adviser on his thesis." "You advised him on a lot more than that." "You were having an affair." "Excuse me?" "We found your little sex dungeon and the message you wrote on the mirror." "Peter broke up with you, didn't he?" "So you punished him the only way you knew how by making him your prisoner." "Then he escaped." "Is that when you decided he had to die, doctor?" "You killed Peter?" "I-it's not true." "Any of it." " You're coming with me." " Wha..." "You open those cells, but no one leaves here until I've returned with the police." "Do not listen to him." "Oh, and, uh, you're indoors and it's dark, so take off the sunglasses." "You look stupid." "Yet another case closed courtesy of Richard Castle Investigations." "Um, who is this woman?" "And are you in handcuffs?" "This man abducted me." "It's not an abduction." "It's a citizen's arrest." "Please get it straight." "Beckett, please meet Dr. Lillstrom." "She was Peter's teacher..." "with benefits." "The real kinky kind, too." "But when Peter ended their trysts, she locked him up in a secret, underground prison experiment, which is where I caught her." "You're welcome, honey." "You went to an underground prison?" "Alone?" "No, not alone." "I had Alexis with me." "Oh, well, since you had backup." "Are you kidding, Castle?" "Your daughter?" "When you say it in that tone, I sound like a bad parent." "Regardless, Dr. Lillstrom is a suspect." " Trust me." " Fine." "Thanks." "There's protocol." "You know that." "If you had a lead, you should have called us." "Oh, believe me, I wanted to, but they locked us up in a cell." "No, I mean, you should have called us be... wait, they locked you up?" "You know what?" "Never mind." "I don't want to know." "Just go find Ryan and Espo and take them to the prison." "That man is insane." "I'm innocent." "If he says you're a suspect, then trust me..." "you are far from innocent." "Let's go." "This way, guys." "Oh, no." "Oh, no, no, no, no!" "I told them to stay." "They're not dogs, Castle." "They're college kids." "What did you expect?" "This place has been completely cleared out." "Dr. Lillstrom must have had a contingency plan." "They took all the evidence." "And I let it happen." "All because I wanted to impress Beckett." "Sorry, Beckett." "I screwed up." "Yeah, you did." "And I jeopardized the entire case." "Again, yes." "But you know what?" "If it wasn't for you, then we'd still be thinking that Peter's prison uniform was a Halloween costume." "So, I've been digging into Dr. Lillstrom." "Did you know that for the past decade, she's been contracting with the army, working psy ops?" "Wait a minute." "The Navy funded the first, the original Stanford Prison experiment." "Maybe the army is behind" "Dr. Lillstrom's modern-day incarnation." "That would explain how the place was scrubbed so quickly." "Now, why would the military be interested in a bunch of college students playing prison?" "Well, the government's in need of new counterterrorism techniques aimed at the millennial generation how to get into the minds of young terrorists and break them." "And what better source of lab rats than the millennials here at home?" "But we'll never get those surveillance tapes back." "So how do we prove that Lillstrom left the prison to kill Peter after he escaped?" "We need a confession." "Well, the doc likes mind games, right?" "Charge me or let me go." "Which sounds better... negligent infliction of emotional distress, or gross psychological abuse?" "What are you doing?" "I'm writing an e-mail to the entire Hud U. Faculty." "Figured I'd let everyone know that you were conducting an unauthorized experiment with members of the student body, secretly funded by the U.S. military." "I'd love to see you prove it, especially because every participating student signs a nondisclosure agreement." "Oh." "Well, then, I suppose you won't mind if I send this." "Wait!" "Wait." "What will it take for you not to tell anyone at Hudson about this?" "The truth." "Do I have your word, captain?" "Hud U. will never hear from me." "Okay." "I didn't kill Peter, and I wasn't sleeping with him." "That's all you got?" "Well, then I'm sending it." "Look, it's the truth!" "The night Peter escaped, I wasn't even at the prison." "Then where were you?" "A pipe burst in my apartment." "I was dealing with it all night." "Check with my doorman." "But if you're thinking whoever was having an affair with Peter killed him..." "I might be able to help." "Now we're talking." "My study deals with extracting secrets from unwilling subjects." "And Peter revealed that he was having an affair?" "So, who was he sleeping with?" "Someone on that list." "Dean Feller, I'm sure you know why you're here." "Actually, I don't." "Well, we found the studio apartment." "I don't..." "I don't know w-what that is." "Really?" "Because we showed your photo to the neighbors." " They were able to tell us that..." " Okay." "Look." "Peter stood me up a couple of nights in a row." "And I was hurt, so I wrote him a message." "Peter stood you up because he was trapped inside of Dr. Lillstrom's prison experiment." "What prison experiment?" "Peter told you about the hell that he was stuck in." "Phone records show that you received a collect call from a payphone near the crime scene." "Yes, Peter called me." "He was panicked." "He told me to pick him up at the park and he would explain everything, but he never said anything about a prison." "He never showed." "Did Peter tell you that Dr. Lillstrom extracted the secret of your affair?" "Is that why you killed him?" "Because he was the only one who could verify the truth?" "What?" "I didn't kill Peter." "I want a lawyer right now." "You're not buying this, are you?" "No confession." "No smoking gun." "It's just..." "Not clean." "Well, that's how homicides are sometimes." "You know that." "Yeah, but something's still bothering me." "There's a part of the mystery that hasn't been solved yet." "We're missing part of the story." "And how do you suggest we find it?" "The same way we always do." "We start at the beginning, back at the prison." "You just want an excuse to get me alone." "No, Beckett, I just want the truth." "What really happened to Peter that night." "Peter was placed in this cell." "And then he escaped." "Yeah, but how?" "They said one morning he was just gone." "So, what are you thinking?" "How Peter escaped had something to do with who killed him?" "Only one way to figure it out." "And guess what." "We're gonna figure it out together." "You're not gonna get a signal." " You trapped me in here on purpose." " No, I didn't." "But since you brought it up, tell me... why do you feel trapped in our marriage?" "I don't." "Then why did you leave?" "It's complicated." "So is breaking out of a prison, so we've got some time." "You know what?" "We're not having this conversation." "I asked you for space, and you literally locked me up in a jail cell." "Okay." "Whoa, whoa, whoa, okay." "Okay." "You..." "I'll give you space." "I'll give you space." "You know what?" "You know, it would be just my luck it would ricochet and hit you and then I'd have two murders to contend with." "Look, relax." "Peter broke out of here, so..." "So can we." "Probably." "You're right." "I mean, we've been stuck in worse places together before." "I like that word... together." "So what happened, Kate?" "What did I do wrong?" "Castle, this one's not about you." "It's on me." "I love you." "I always will." "Then let's work it out..." "therapy, counseling." "Whatever it takes." "I..." "I just can't." "Why?" "Huh." ""Huh," what?" "Before this place was a prison cell, it was an office building, right?" "Yeah." "Take a look up." "I bet you that's how Peter got out." "Come on, Castle." "Uh, this is when you boost me up." "Uh, right." "Up." "Ready." "There we go." "Uh, okay." "Oh, got it." "Whew." "You're doing great, honey." "N-not to rush you, but..." "Wait a minute." "Something's not right here." "How did Peter reach the vent from inside the cell?" "It was a two-man job." "Two prisoners escaped, but only one was missing, which means..." "The killer came back!" "I'll open the door." "Thanks for coming down to the station, Emily." "We just have a few questions about the prison experiment... and how you helped Peter escape from it." "What are you talking about?" "Well, Peter reached through the bars, and he hoisted you up, and you both escaped, didn't you?" "And then you killed Peter in the park and returned to the prison, to your cell... the perfect alibi." "That's ridiculous." "Why would I kill him?" "Emily, we know about the scholarship." "You needed it to stay in school." "Yeah, but he won fair and square." "We know that's not true." "Peter won that scholarship because he was having an affair with the Dean." "And then when you found out about it in the prison, you took your revenge." "It wasn't me." " Stop lying, Emily!" " It wasn't!" "It was a different me!" "That experiment messed with my head!" "After we escaped, I just... snapped." "It was so unfair." "I had worked so hard, did everything right." "When Peter ran into the park," "I-I went after him." "Then I saw that tree branch." "Why did I do that?" " Thanks for meeting me." " Yeah." "I finished piecing this together for our investigation." "You're having second thoughts." "Aren't you?" "Yeah." "I just knew that this was gonna be tough." "I didn't think it was gonna be like this." "I get it." "I do." "Look, maybe we need to stop before we start." "Beckett, I'll follow your lead." "What should we do?" "Let's get to work." "That is... 50-year-old scotch." "Yeah." "I bought a case of it." "Alexis, that's expensive." "Relax, dad." "The company paid for it." "Oh, okay." "W-wait." "That means I paid for it." "To closing the case." "To generous expense accounts." "So, any progress with Beckett?" "You know, at the prison, we, um, sort of had a moment." "Really?" "Yeah." "I think my plan is working." "I mean, it has to, right?" "Um, you know what?" "We're gonna start a tradition." "For when we solve a case together." "I don't smoke, and neither do you." "Who said anything about smoking?"
