Battlestar Galactica, Season 1

[Roslin visits Baltar in the brig after he is accused of treason.]

Roslin:
I want to believe you. I want to believe that I haven't made such a profound error in judgment in trusting you, in asking your advice. But here's where we are, Doctor. If anyone can be a Cylon, and it's hard to tell us apart then we o­nly have o­ne thing left to trust. Our instincts, our feelings. And the moment they told me it was your face in the photo I knew I believed it. I believe you were involved in the attack... somehow. I feel it.

Baltar:
You'll forgive me, Madam President, if I don't wish to be executed based solely o­n your gut feeling.

Roslin:
May the gods have mercy o­n your soul.
