Blade and the Vampires

There's exposition about how blade ended up the way he is. Whistler gives us a sermon sort of on how blade works. He says, you know, I found him when he was 13, he was drinking blood. We learned that his family was tragically killed by vampires and he's been hunting vampires ever since. And then Quinn runs away. And they escape a blade and Karen escaped by hopping on to the subway train.
