Deb is surprised that Dexter wants to go to his reunion given how much he hated high school. He tells her he's going there to get laid.
But in the car we see that he is only going for one of his special cases. A female classmate and special friend of his used to be beaten by her football star boyfriend Joe. The two married and when she was killed a few years ago Dexter looked into the case. Despite the case being ruled a gunshot homicide she had traces of blood under her nails.

In the bathroom Harry tells him that he became popular since he's suffered recent tragedy and looks better than he did in high school where he was not popular. Harry thinks he should enjoy the popularity.
Dexter is having drinks and holding court. He finally makes his way to Joe. who gives him a fist pound instead of a handshake, thwarting his plan to obtain a blood specimen.

Dexter notices there will be a homecoming flag football game the following day.

Dexter brushes up on his football knowledge before Deb tells him they have a case.
The crime scene is the fruit stand. There are human intestines on the scale. Dexter follows the blood to a large pool down a hill. But there is no body. Quinn nervously tells Deb he wants to talk to her later. They are living together.

On his way to see Joe, Dexter runs into the reunion hottie Trisha. She pushes him into a classroom. After thanking him for the fact she copied off his papers all through high school, she performs oral sex on him. To his pleasant surprise she doesn't want to stick around and talk.
