I've a few favourite quotes from Smallville over the years, one of my favourites was from season one. Now I come to think of it, Dr. Fate wasn't that special because there have been at least 2 other people who could see peoples futures, this one isn't actually the same if I recall correctly she sees like riddles or hints about someones future.. anywho this quote comes from her from the episode Hourglass in season 1.
(She's talking to Clark about other people's futures she has seen) - "No, Clark, I've seen you...before we ever met. More than once, I've touched people, and I've seen such pain and despair and-- but then you were there, and the pain was gone. I think that's your destiny, Clark--to help people, to save them from fear and darkness. "
It isn't a particularly great quote in terms of writing however the actress delivered it superbly.
