Still fantastic stuff. If not for the fact that the Final of the Final Five hasn't been revealed - I would have been satisfied with this as the end of the series.
Now I was ALMOST right. I had originally expected the Demetrius to reach Earth in this episode and that it would activate Gaeta. Of course, since this ISN'T Season 3 and the Demetrius plotline resolved itself much more quickly than I expected... I threw most of that theory out the window.
But here we are! Irradiated Earth! Now we have 10 more episodes for flying motorcycles and murder mysteries! Er... no...
please no.
Now for theories!
Starbuck did visit Earth. She left behind an emergency transponder attuned only to her Mystery Viper. Why she's forgotten or how she got the Viper I still don't have worked out, since I still highly doubt she's the final Cylon.
I'm leaning towards Gaeta still for final Cylon now that I've all but abandoned my Roslin bet - and I think he's already activated. Gaeta is the one who confirms that the Mystery Viper is receiving a signal. Gaeta is the one who confirms the constellations. No one checks his work. Gaeta could easily be up to something.
The series will end with Humans and Cylons returning to Kobol together.
