Okay, imagine that Bella didn't forgive Edward after he did that douchey thing in book two. Imagine instead she thought, "Hey, I'll shack up with Jacob instead. He's hot too, he's not creepy and he's way more fun."
....and that is why True Blood/Sookie Stackhouse is better than Twilight.
(Dear Twi-hards, I love Twilight. Honestly. I've read all the books, even the last one, and I made Mr London watch the film (you can read his haiku on it here.) I'm just Team Jacob, is all.)
