Betty: Why are you getting so upset? It's just a party, Jug. Jughead: It's not just a party. It's the fact that you don't know, or even care, that this is the last thing I would want. You did this for you to prove something. Betty: To prove what? Jughead: You're a great girlfriend? I don't know. Doesn't it ever occur to you how different we are, like on a cellular DNA level? You're a straight-A student, a cheerleader. For God sakes, you're the perfect girl-next-door. Betty: I hate that word. Jughead: I'm the damaged, loner outsider from the wrong side of tracks. Betty, come on, who are we kidding?! We're on borrowed time.
Betty: I should've told you about Chuck, but I lied. And instead threw you this party you didn't want. Jughead: Why did you? Betty: Something is very...very wrong with me. Like, there's this darkness in me that's overwhelming. Sometimes I don't know where it comes from, but I think that's what makes me do things.
