So wow. That was kind of a mind frak, huh?
************* THERE BE SPOILERS HERE *******************
I'm going to need to give last night's epi a rewatch about 3 or 4 times, but here's the sitrep:
Earth is definately a nuked out POS, and has been for about 2,000 years. Dualla finds a pocket watch and some jacks in the ash, and is very sad about it. Tyrol remembers shopping in a farmers market on the day the Earth died. Anders and Tory also have memories of their lives on Earth.
And how is this possible? Because besides than the fact that all this happened 2,000 years ago, it also turns out that everyone on Earth was a Cylon.
Just deal with that for a minute. You can now add "glowing red spine" to "flying car" in my list of things that Science Fiction has promised me that I don't have yet.
Everyone is understandably gutted at the news that Earth is a cinder, and deals with it in their own way. Dualla deals with it by going on a date with Lee and then BLOWING HER FRAKKING BRAINS OUT WITH HER SIDE ARM.
Farewell, sweet Dee.
Meanwhile, Starbuck and Leoben are still on Earth, trying to find the source of the Colonial distress signal. Following a trail of debris they find it ... coming from KARA'S BURNED OUT VIPER WITH HER CHARRED REMAINS STILL SITTING IN THE COCKPIT!
BUT! Lest you think, "Oh that's a let down. Clearly, Starbuck is the final Cylon what with the whole coming back from the dead, and "Don't freak out", and what not.", she's not.
Ellen Tigh is the final Cylon. As we see when Saul walks into the sea, and has a vision of his last day on Earth, searching desperately for his wife. Ellen. Who tells him they will be together again.
All this has happened before, and all this will happen again.
