Another scenario in my head is maybe they get kidnapped and are forced to strip and get into bed and locked up in some motel. I watched the re-run of the episode where Sully leaves on his boat ('The Boneless Bride In The River'?), and Booth is there to comfort Brennan and he reads her mind instantly. He know she's afraind she'll never find love or happiness or the one who's for her, and Booth's assuring her she will, and she just has to be ready when it comes. Well the time has already come, just that Brennan doens't realize it. Cos Booth's right there for her. Another thought, you think Sully might be back? Would make things interesting for B&B, and Booth would definitely be jealous. Personally I hope he doesn't come back.
