Xena: Warrior Princess, Season 1

Xena:
Tell me truth, Marcus. You were put with the wicked when you died, didn't you?

Marcus:
Well, like your friend says, hard to make up for a lifetime of evil with single good deed in the end.

Xena:
So if we succeed in putting things right, you will spend the rest of eternity in Tartarus with the very people you are about to betray. Why are you doing this, Marcus?

Marcus:
Xena, I died doing a selfless act. You taught me how sweet that could be. I knew you'd do the same thing if you were in my place.
