Adama and Lee in “Crossroads, Part 1”

After what you did to Tigh, you're the last person I'd confide in.

Lee

Me? I didn't do anything to Tigh. He was drunk. It's really not my fault.

You told Lampkin about Ellen.

Lee

I didn't even know about Ellen.

Yeah, right.

Lee

You're calling me a liar?

I'm calling you a liar and a coward. One who doesn't have the guts to go after the man himself. Instead you hand the shiv to a stranger. Let him stab Tigh in the back. And for what? Traitor, piece of garbage, Gaius Baltar. Doesn't even deserve a trial.
