It's not a huge part of the movie. There's just a scene where another character realizes she's having GIRLFRIEND PROBLEMS.
The director says, quote, "She's questioning a lot about who she is. She hasn't fully figured it out yet. I think what's great about that scene and what that scene propels for the rest of the movie is, 'That's OK.'
"The movie is saying, 'That's OK,' and all of the kids have to own who they are and find their tribe."
She's being played by rap minx BECKY G.
