Eddie was introduced in season four, episode one. He and Chrissy were doing a drug deal and went to his trailer.
When she got there, she was killed by Vecna. He is accused of the murder because he ran away from the scene when
Chrissy was getting crumbled. He spends the entire season hiding from the cops and staying in the open. The town hated
him for a crime he didn't do and he was killed by Demobats in the Upside Down and died a hero.
