Feeling betrayed by Roslin, Baltar gives Gina the nuclear warhead that he used as part of his Cylon detector.
We learn that Roslin was having an intimate relationship with President Adar before the Cylon attack on the Colonies.
President Roslin is infused with some of the Cylon/Human fetal blood from Sharon in order to cure her cancer.
There are 49,598 Survivors.
189 Days have passed since the initial Cylon attack in the Mini Series.
Sharon: I've done nothing but help them since I've come here. I've held back my anger. I've tried to show them that Cylons are not all the same. That we're not all murderers.
Helo: Deep down, I think they're still afraid of you.
Sharon: Yeah. Afraid. They wanna be afraid of something?! Yeah?! Just let them come! Let 'em! Let them try and take my baby!
Helo: I don't understand - Sharon has only helped us since she came back from Caprica. She even turned on her own!
Adama: To save her life. Don't mistake the will to live for genuine compassion, Lieutenant. She's still the enemy.
