In the Season 1 episode "Jimmy's Jimmy," it was clear that Billy and Greg had not met before. Now, it turns out that they had.
In this episode, along with "House of Cards," we learn that Kim was Greg's first girlfriend when he mentions that he never had a girlfriend all through high school. But in "Johnny Ampleseed," he did have at least one: Stacey.
