DEAN: I’m so sorry, Rory.
RORY: I’m sorry too.
DEAN: I don’t even know what happened.
RORY: We had a fight, that’s all.
DEAN: I mean, I’ve just missed you and …
RORY: I’ve missed you too.
You can see that Rory is now far more assured and secure in her relationship after her third fight with Dean. Compare her calm attitude after this one, where she actually did behave rather badly, to the huge effort she made to “win Dean back” after a minor disagreement about an old television show. She knows now that Dean loves her and won’t leave her, and just a simple apology will get things back on track so they can kiss and make up.
