Ok... turn away now!!! if you want to avoid spoilers to Season 3 main event- involving Kara Thrace aka Starbuck...
Right is she dead or not?
Well, first off. If that was the cylon Leoben that was talking with her- or projecting images into her mind - why would he entice Starbuck to kill herself? He's been trying to form a relationship with her all this while, and got killed many times over trying to do it (on New Caprica).
Second, Starbuck realized that - that was NOT cylon Leoben, and the person confirmed it by saying that, "I never said I was". Well, make of it what you will. But it could be another entity.
Third, there was indeed a Cylon raider out there. If you replay the scene, you can clearly see it when Apollo sights Starbuck for the last time.
Question - what was it doing there??? And notice that Starbuck's hand was on the ejection seat.
Its quite likely that she ejected and was later picked up by the Cylon Raider.
However, we will probably not see Starbuck for the rest of Season 3 and most of Season 4. Meanwhile, her name is removed from the credits to increase the suspense.
So stay tuned.
