>>106806621It's called the Toedad Saga and BOY is it a mess.
Long story short: It's Becky™ runs away from home and moves in with Joyce at college. While Becky becomes a nuisance and begins pretending she's in love with Dina, Toedad learns where she is and goes to collect her. In a confrontation he pulls out a rifle and begins after the two; they split up and while Dina is able to distract Toedad before mysteriously disappearing, Becky reaches Joyce at a fountain. Toedad finds them and collects Becky since apparently there is no campus security to immediately suppress the threat. Joyce gets mad and, with the help of Sal, goes after the two; Amazigirl is also there for whatever reason. Anyways, Toedad's car flips, he's thrown out of the car while Becky (still inside) escapes with no physical injuries. Then Joyce punches Toedad so hard that she breaks her wrist.
Or something like that. The gist is the same, but the details are a bit fuzzy since this happened years ago.
