Lorelai: I just want to tell you that I think you are scum.
Dean: Gee, thanks.
Lorelai: You are going to be hard-pressed to find another girl as fantastic as Rory. You know that?
Dean: What are you-
Lorelai: She is beautiful and smart and did not deserve to be treated that way by you.
Dean: Treated what way?
Lorelai: I thought you were a good guy. I thought you were going to make her happy. I was such an idiot. I thought you were a good pick. But I was wrong, and I hate to be wrong.
Dean: I am sick and tired of everyone blaming this thing on me. I mean, you and this whole stupid town looking at me like I'm a criminal. I say, "I love you", and she just sits there, and I'm the jerk? I'm the bad guy?
Lorelai: What?
Dean: You know what? Fine, think what you want. I don't care. Just leave me alone.
