Battlestar Galactica is seriously fucking with my head.
Tigh is a Cylon. Adama had a breakdown over it and Lee's runnning things. Eeeeeek! Then, horror of horrors...the humans and Cylons come to an out of nowhere agreement, everybody's happy, let's beat it to Earth.
Only...Earth's a desolated, ruined shell. No people, no nothing. OUCH. How cruel.
