I think it was this LaCroix quote (as the Nightcrawler):
Love. It warps our senses, twists our souls...can take us past hope, past cure, past help. I know about love: it's suffering, it's anguish, it's pain. Heaven makes means to kill our joy with love. And yet we must have it, at any cost. But are you so enamored that you'll overlook your love of life? And you do love it. I've seen you smell the sea, gaze at the stars at night. Are you willing to sacrifice one mistress for another? Look into your heart and tell me that you're willing to make the choice.
It was from Last Knight. Which reminds me, as sad as it was, it was also one of the more romantic eps in a way. I mean, not the whole depressing thing but Nick's love for Natalie. The directors originally wanted it to be like Romeo & Juliette.
I heard through the rumor mill on forkni-l that Catherine Disher tried to move, to let the audience know that Natalie was still alive, and that was edited out. There was a conflict because James Parriott's vision wasn't the same as Ger's, who was directing at the time. So they compromised by ending with LaCroix holding the stake, but we never see Nick die. Which, of course, lends itself to all sorts of interesting possibilities with fan fiction.
