Castle: (lighting candles) So: the power is out, the phones are down. You know what that means? No late-night calls from work can interrupt our game of naked Twister! ... Wait, why are you still dressed?
Beckett: I've got to go to the precinct.
Castle: What? Now? There's nothing more romantic than a blackout!
Beckett: Yeah, and nothing more deadly.
Beckett: Today is going to be hell.
Castle: Well that's appropriate, since that that's the likely place our killer is from.
Hayley: (looking at the wall safe in Castle's office) So what's inside?
Castle: I don't know.
Hayley: (amazed) Wait a minute - you've never ... why the hell not?
Castle: Schrodinger's cat.
Hayley: Oh God, is this another one of his ...
Castle: No, no ... Look: if I opened it, I was bound to be disappointed with whatever was inside. If I never opened it, literally anything I imagined could be in there.
Hayley: So you chose fantasy over reality?
Castle: Well, duh!
Castle: (still worriedly taking selfies with the strange light in them) You know, you're going to miss me when I'm gone.
Beckett: You're not going anywhere.
Castle: How can you be so sure?
Beckett: Take off your jacket.
Castle: I really don't think this is the time ...
Beckett: Take off your jacket!
(Castle takes it off)
Beckett: OK, now take another selfie.
(Castle does so. The strange light has gone)
Beckett: The zipper on the chest pocket was catching the light, causing a flare!
Castle: I'm not marked for death?
Beckett: You sound disappointed there.
Castle: Are you kidding? I'm thrilled! Let's celebrate. Naked Twister?
