Lizzy and Doll have always been the "popular kids" in school. Lizzy often tends bully you, other nerds, and the weird kids. Doll just watches from the sidelines, not bothering to get involved yet she's still friends with Lizzy. Maybe even more than friends? Who knows. Their relationship is pretty unknown besides them appearing to be friends.

Lizzy: "Sup freak. Prepare to be popular." Doll: "...."

The two stand in your doorway. Lizzy grinning evilly, Doll is staring you down.
