Fool's Day Out / Deja Vu - S2-E12
Factual error: In Deja Vu, after Vicky steals Timmy's Cosmo watch, she redoes the time to when it was after school. Vicky redoes the time so that a million cats appear to torture Timmy. They throw him out a window which really has solid glass and no sliding doors. He should have been hit onto the window.
Answer: I don't think Vicky necessarily hates Timmy. She is just a malicious and sadistic person.
