"By who?" "He would only say by "them."" "I thought he was imagining it." "I told him he needed to get help" "So it didn't become m.I.T. All over again." "What happened at m.I.T.?" "Freshman year, will had a breakdown." "He cracked under the pressure." "That's why he left." "But if somebody killed him," "Then maybe he was being followed." "Beckett:" "Okay, here's a theory." "What if will had another breakdown?" "What if he imagined that the devil was after him," "And in his delusional state, he smashed up his apartment" "I mean, we've seen guys on pcp do much worse."

"Greenblatt's only office is in chicago," "But his neighbor said he saw him go into work every day." "Yep, and his greenblatt key card" "Was with his house keys and all scratched up, worn."

"And with a functioning suit," "Henry could've enlisted will's help" "Ryan:" "But henry still needed help defeating talmadge's home security." "Invisibility doesn't defeat thermal or pressure systems." "So, they hustled jiggy" "While henry was wearing that invisibility suit." "Henry is the one that was moving the cue ball around the table."

"Stop him!" "Stop!" "[ grunts ]" "Who's got the falchion sword now?" "I didn't murder will." "He was my friend." "Then why did you run, henry?" "Look, we know that you went after tom talmadge." "You were behind a cyber attack" "That brought down a government lab," "And then you cleaned out your apartment and you disappeared." "Because I was afraid that they would come after me next." "The same people that killed will." "All right, if they found out that I knew..." "That you knew what?" "You helped him, didn't you?" "You helped him build a working suit." "Will came to me with an out-there idea." "He wanted to adopt nature's camouflage" "To meta materials." "That had my program skills, and since there was no way" "I was gonna get security clearance," "We worked on the down low." "And in exchange, you got to use his suit" "To exact your revenge against talmadge, right?" "That wasn't supposed to happen." "I was just looking for proof" "That tom stole my idea for hytch." "Yeah, well, his broken ribs say otherwise." "I couldn't find what I needed." "And then tom came home early." "I-I just wanted to mess with him." "But I snapped." "Will heard the struggle, he came in, and he pulled me off." "You got angry with will for stopping you." "So, you decided to use his suit to kill him instead, right?" "We both realized that I had become frodo," "And the suit was the one ring to rule them all!" "Will knew it was too much power for anyone to have," "Especially the government." "So, that was will's oppenheimer moment." "The suit became the atomic bomb." "All right, it needed to be destroyed." "Cast into the fires of mordor." "We sabotaged the lab so that they couldn't rebuild the tech," "At least not right away." "And without the quantum cellular equations" "Will derived from cephalopods," "They may never be able to." "Cephalopods?" "Like squids?" "Actually, um, will," "He based his equations off of the cuttlefish." "Narrator:" "The cuttlefish is known" "As nature's king of camouflage." ""the papillae of the cuttlefish are unique in their ability" ""to rapidly polarize reflected light waves" "And change the creature's skin color."" "That's why will got back in touch with donna." "He didn't want her." "He wanted her research." "Castle, look at will's phone records." "For weeks, there were phone calls" "Going back and forth between the two of them," "And then three days before his death," "Right when he got that suit to function," "There were only incoming calls from her." "Will wasn't answering." "And right after will was murdered, she stops calling," "Almost as if she knew he was dead." "Hey, guys." "I called the university." "Guess who canceled their class the night will was killed." "Brooks:" "What's going on here?" "This is a private office." "The dean gave us permission to search it" "As a part of our investigation." "Wait." "You think I had something to do with will's death?" "Donna, you missed your class the night that he was killed." "Where were you?" "At home with a cold." "I never would've hurt will." "I loved him." "You loved him, but then he betrayed you." "That must have made you angry to find out" "That he was just using you for your research." "That's not true." "That was the second time that he left you," "And you couldn't live with the embarrassment." "This is ridiculous." "And let you accuse me of killing my boyfriend." "Donna, that was you in the suit in the apartment with us." "That's the same suit that you used to kill will." "You found out about his project," "And before he could destroy it," "You used his own creation against him." "What suit?" "What are you talking about?" "The suit you wore when you went after will's key card" "And you got my credit card instead." "Just found it buried in the back of your drawer." "Thank you for that, by the way." "I forgot to cancel this." "That can be such a pain." "What was I supposed to do, let him get away with it?" "He stopped calling, stopped texting." "He used me!" "And then pretended like I didn't exist." "He wanted me to just disappear from his life." "So I did." "And he never saw me coming." "Donna brooks, you're under arrest " "[ grunts ]" "You go." "Okay." "Okay." "Okay, I'll get this." "Castle:" "Her backpack and clothes." "She's wearing the suit." "Castle, block the door." "Right." "She is not slipping past this time." "Donna, there's nowhere to go." "[ chuckling ] yeah, gotcha now!" "I so missed these mind melds." "2:00!" "She's right there." "Beckett, what would you do if you were invisible?" "I'd walk out of here without having to file this report." "Mm." "Boring." "Yeah." "I know." "How about you, castle?" "Be a fly on the wall, see what beckett's dad really thinks of me." "Hmm." "Hmm." "What's this?" ""time you had a proper uniform." "Love, javi."" "It's from the heart, bro." "Okay." "[ clicks tongue ]" "Too big?" "Want to help me try it on?" "[ sniffs ] ew." "They told me it was new." "I could really use your help." "What?" "Blue is my color." "What's wrong with you?" "[ indistinct conversation ]" "You don't have to be embarrassed." "We'll be taking custody of that, mr." "Castle." "You know, will thought this was too much power" "For any one person to have," "And after everything that's happened," "This kind of science is a bit of a deal with the devil." "Be careful not to lose your soul." "Mother is out for the evening." "Alexis is pulling an all-nighter at the library." "So, we're actually, truly really alone?" "This came in this morning." "Switching to thermal." "[ goggles whir ]" "Scanning the room." "The room is clear," "All except for the very hot object before me." "Give me a minute and let me slip into something special, okay?" "Right." "'cause there's something special" "I got you for valentine's day." "I approve." "It's even better." "It's invisible."
