Chuck:The reason Blair attacked you is because she misses you. Don't tell me after 18 years you can't read Waldorf subtext?
Serena:I shouldn't have to, if that's what she's feeling then she should tell me. It is time for her to grow up.
Chuck:This coming from someone who just pushed her best friend into a cake.
Chuck:Look, you think your friendship is going to take care of itself, you're not kids anymore. You can't say you hate each other then make up an hour later on the Met steps.
Serena:You tell her that.
Chuck:I'm telling you and you should be careful. Because one day you're gonna find yourself telling people about Blair Waldorf. The girl who used to be your best friend.
