This is the film character, See: Book Version
Olivia is the shy girl of the group and lives with her grandma after her mother died when she was a child. While it was never explained why, her father was put in prison. Although Olivia loves him, she is embarrassed to talk about him or to him; which may explain why she is so shy.
She narrates the whole movie through a letter she writes to her dad. In the book, after she writes a letter, she goes with the other members of Lemonade Mouth to visit her father in prison.
The only thing she has left of her mom is her cat, Nancy. In the movie, the rest of the band wonders where she was, and they walk to her house. They find Olivia in the backyard crying since Nancy, her cat died. She doesn't have a lot of friends since she is very timid. She's a mega bookworm, and is very intelligent proven when she provided a correct definition for Determinate to Wen, however she doesn't have a lot of confidence. She does not like lots of attention (as it causes her to throw up), but she is an amazing singer and songwriter. She typically wears dresses with large belts and short cardigans.
"Olivia is a shy girl who lives with her grandmother and her cat. The last thing Olivia wants is anything that draws attention to herself, but she's an incredible singer and songwriter and her growing feelings for Wen, Lemonade Mouth's future keyboardist, convinces her to give the band a shot."
- (To Wen about her grandmother's remark about her first encounter with Olivia's friends) "She was just kidding about the whole friend thing. She's met a ton of my friends, tons and tons of...friends."
- "That was nothing. I...I think I'm gonna be sick."
- "But it's probably not the best idea to go out there. You know, physically."
- "Yeah, I don't think that's such a good idea. Last time I got on stage was our first grade concert, and five minutes into Baa Baa Black Sheep, I threw up down Mikey Nichol's back."
- "And that was how we got our band name"
- (To Wen) "FOR YOU, YOU JERK... I did it for you."
How She Got Detention
Olivia is caught skipping class while reading in the janitor's closet. Outside, Principal Brenigan rides his segway past when all of a sudden, the cleaning supplies fall over on her and cause a loud wreck. Principal Brenigan hears the commotion and casually hands Olivia a detention slip.
Olivia lives with Gram and they like to play chess, checkers, or pinochle and listen to classical music together.
Olivia and Wen are friends. Olivia does not like Wen at first, but begins to trust him as the story progresses. She also teaches him how to value his family as he always helped her in difficult times such as when Olivia began to feel sick before the Halloween Bash performance. In a deleted scene, Wen claims Olivia was his girl during an interview. (See Wenvia)
