Battlestar Galactica, Season 4

Thrace:
When I woke up orbiting Earth I just figured it's some crazy dream. I went in following the heavy raider. I mean maybe the Cylons pulled me out of the suit.. Captured me, brainwashed me. On Caprica they experimented on me. I mean did they take pieces of me.. Is it possible that they grew me, another me in a petri dish.. Implanted me with the memories or it with the memories, or.. I don't know.

Anders:
No, no no no. Hey, no. Kara, no. Listen to me. If you're a Cylon, then you've been one from the beginning.

Thrace:
Like Boomer. Spend my entire life thinking I'm one thing..

Anders:
..And then you wake up one day and discover you're another. Still doesn't change who you really are. Still doesn't change the fact that I love you, no matter what.

Thrace:
You are a better person than I am because if I found out that you're a Cylon I'd put a bullet between your eyes.
