Betty Rotweiler

Bettina "Betty" Rotweiler is Becky Detweiler's 98th Street counterpart and CJ Rotweiler's sixteen-to-eighteen-year-old sister and a supporting character in C.J. and Friends: School's Out.

Personality
Betty is C.J.'s sarcastic yet beautiful big sister. While she is nice to her friends and parents, she can be rather mean and rude to her younger sister and her friends. While Betty finds C.J. an annoyance, deep down, she cares about her. C.J. is roughly at the height of her collar in the movie. In C.J. and Friends: School's Out, C.J. makes her drive across the state multiple times to pick up and drop off her friends from their camps in order for them to help her with her plan, or else she will post her diary on the internet. Once C.J. is captured, the rest of The Recess Gang try to get her to help her, with her refusing. She finally decides to help them once Mickey tells her that she needs to save C.J. because she is her little sister and needs her. She then drives the gang to pick up their campmates, and she helps out in the battle against the villains. After the fight, C.J. gives back her diary and she tells her that maybe she is not such a bad little sister after all. Despite her mending her ways with C.J. at the end of C.J. and Friends: School's Out, she goes back to being mean and rude to her and her friends in C.J. and Friends: Taking the Fifth Grade. However, this may be due to keeping up appearances and they may still get along.

Relationships
According to C.J. and Friends: School's Out, Betty's dating one of her co-workers, Tommy. He is never seen interacting with her in the movie, but she writes about him in her diary, and she has his picture up in her room although she might of broken up with him because she was telling her friend Alicia that she was through with him because he asked her if she spoke French and then winked at her.

Appearance
Betty has an average height with a slender build and (slightly longer than) chin-length blonde hair. She usually wears a blue sweater, purple jeans, and sneakers. Her eyebrows vary several times from her animation and expressions.
