Re: Castle - Season 6 Discussion & Spoilers
I think either a) Beckett will leave on her own or b) she brings Castle in to help like he's always helped her in the past and that doesn't fly with her superiors who wonder 'this woman can't work without her writer boyfriend' and she's basically let go. or c) She works for them sort of as a 'reserve' agent or something and goes back to NYPD.
I really don't think they'd do anything to potentially kill Castle this isn't a JJ Abrams show.
