Oh some "End in the Beginning" talk!
This makes me happy!
From what I've gathered, the finale is a "dream sequence" (as quoted by an extra), which occurs after Booth's surgery. I assume that it's a dream while Booth is in
surgery, but very little is actually known about all of this--dream or hallucination? Whose dream?-- I say Booth or Brennan's dream before
they have sex.
In the finale, I know that there's a dream sequence in which B&B are at least engaged and own a nightclub called The Lab which is actually on the exact same set as the Medico-Legal lab. There's a case/murder where everyone is suspect--including Zack (Eric Millegan) who is guest-starring. Caroline Julian, Max, Jared & Birimbau as well as a half-dozen squints (Daisy, Wendell, Vincent...) are also guest-starring. Booth has a scar/stitches above his left eye-brow (perhaps integrated into the dream b/c of the surgery). Brennan has a wedding ring on her left ring-finger. I also know that Cam is the police officer in the dream as she has a badge on her hip in one photo. I also know that John Francis Daley's band, Dayplayer, is playing two original songs under the stage name "Gormogon" in the finale--the songs will be released after the show airs. Also, Motley Crue is singing in The Lab "Doctor Feelgood" to over 300 extras who are rocking out. And apparently Tommy Lee knew nothing about continuity and kept taking off and putting on his shirt. Hodgins' character is supposed to be a "regular" of The Lab's bar, Angela is supposed to be a waitress/hostess, Cam a cop, B&B own the nightclub, Sweets has the band, Max is a regular... not sure what Zack's part is yet.
I also know that the circumstances surrounding how
B&B get into bed are mysterious and unusual
. It's supposed to have something to do with the baby scenario and the whole episode is supposed to end in a "cliffhangerish" way (according to Emily).
There we go. We're all caught up... unless I missed something!
