Billy has a lot of rage built up, he takes it out through the typical ways; sports, punching stuff, & murder. Steve didn't realize he liked being used until it started, and Eddie didn't realize he had a thing for Steve until Billy Hargrove started perusing him. What's a little bit of stalking? What's a little bit of blood? TLDR- Steve becomes the object of obsession for a serial killer and a stalker These are not healthy relationships - but they are consenual to an extent! If you or someone you know is in a relationship like this please seek help or call authorities
