For the first time since Michael's death, Charlie goes to the high school football game. He doesn't really watch the game—our guy is more of a people watcher.
Charlie sees the kid from his shop class at the game, the one he still calls Nothing.
Nothing—who calls himself Patrick, of course—introduces Charlie to Sam, a very pretty girl if you ask Charlie.
Now that Patrick has introduced himself as "Patrick," Charlie figures he'll call him by his actual name.
After the game, the three teenagers go eat at the local Big Boy. Topics of conversation include favorite songs, movies, and books; and Charlie finds out that Sam and Patrick are step-siblings.
Charlie really wants to ask Sam out on a date, but he doesn't. (Hey, what do you expect from a wallflower?) But that night, he has a sex dream about her. Yikes. That's definitely the stuff you only find out if you're reading someone's diary—which we essentially are.
He wants to tell her about it because he's ashamed, but he definitely doesn't want the dream to ruin their new friendship.
