- “Sorry, guys, but you two have put me off dating for at least four years. I think I'll just buckle down and co-produce my Dad's movie.”
- ―Greta Wolfcastle
Greta Wolfcastle is the daughter of famous actor Rainier Wolfcastle.
History
She is first seen being bullied by Jackington and two other bullies, who play keep-away with her backpack. She is saved by Bart and they started to go out. After Bart decided she was becoming too needy, he broke up with her, which led to Greta dating Milhouse to get back at him. Bart, now jealous, decided to do everything he could to win her back and followed her to Canada where he and Milhouse got into a fight during a curling game. In the end, Greta broke up with Bart and Milhouse and decided to stop dating for several years so that she could produce her father's movies. She was later seen standing in line with her dad for ice cream, but she never said anything [1].
