What if
...Gianne had been Kara's sister?
...Kara and Lee were together and she almost (or did) cheated on him with Zak?
...Kara had gotten shot in Sacrifice instead of Lee (not necessarily by him)?
...they'd been transported somewhere else when Kara put the arrow in the archer's bow?
...Lee had chosen Kara as his XO in/after Razor?
...Sam had realized he was a cylon on New Caprica?
...Dee had gotten pregnant?
...Kara and Lee had gotten trapped in the airlock instead of Chief and Cally?
...Lee or Kara discovered they were a cylon when they ran into another model of themself?
...Bill had died when Sharon shot him?
...Kara had started an actual relationship with Baltar after Colonial Day?
...Kara and Zak had actually eloped/gotten married?
...there had been a musical episode of BSG--(what would it have been about--who would have sang--what would they sing)?
...the show had learned they were going to get cancelled at the beginning of Season 2? or Season 3?
LOL. These are all incredibly angsty aren't they? Maybe you have some happier ones to suggest...
Pilots contemplate my list and Lee gets bummed out by all the angst.
