Lane: I would've told you earlier, but I thought you knew.
Lorelai: Why would I know?
Lane: Well, Luke was standing right there when it happened.
Lorelai: You knew?
Luke: Yeah.
Lorelai: Luke, did you forget to tell me?
Luke: No. I just thought that Lane would wanna tell you herself.
Lorelai: You forgot to tell me.
Luke: Fine. Sure. I forgot to tell you. So what? I remember being engaged to you, isn't that enough?
