TikTok user @effedupstories has a “Family Guy” fan theory that could explain why Peter Griffin treats his daughter Meg so poorly.

The theory suggests that Meg caused a car crash that killed the Griffin family, save Peter. The show takes place inside Peter’s mind while he’s in a mental institution.

Meg causing the car crash fuels Peter’s resentment towards her, which explains why he acts so antagonistic towards her in his delusions.
