over for them. Ryan asks if hes told her nothing is going on with Anna. He says hes tried, but he cant get a word in. Ryan says hes not going, they can hang
out together. Seth says he loves him, but if he has to spend his senior prom playing
videogames with him then hell kill himself. Seth thinks Ryan should go, ask Taylor or Theresa or something. He says its just one night, Theresa could get a sitter for the night. Ryan says hell think about it, and he appreciates him not bringing up the idea of
going with Marissa. Seth knows that is the past and he thought shed be going with the surf
Nazi, who apparently is currently making out with some girl at the end of the pier. Seth says maybe its his cousin, his really dirty cousin.

up to think she was meeting someone from Brown. He says give him two minutes, he ordered pancakes for her. She sits down and sees prom is written on her napkin. She says this wont make her forget seeing him and Anna at Brown or at the airport saying goodbye.
