Kai Winn:
Remember your place, Dukat.

Dukat:
I thought my place was in your bed.

Kai Winn:
That was before I knew who you were.

Dukat:
Adami, I'm not the same man I was during the occupation. The Pah-wraiths have changed me.

Kai Winn:
But they can't change what you did. Do you really think I could let myself be touched by a man whose hands are stained with the blood of my people?

Dukat:
When we do release the Pah-wraiths from the fire caves... your hands will be stained as well.
