Carmen Molina is the Assistant Principal, and then later Principal, at J. P. Wynne High School.
In the aftermath of Walter White's cancer diagnosis, she proved very understanding, approving his various medical leaves.
She often appeared at school events, such as the meeting regarding the theft of lab equipment ("A No-Rough-Stuff-Type Deal") and the Wayfarer 515 assembly. Later, she tried to talk to Walter about his unusual behavior, but Walter attempted to kiss her. As a result, she placed Walter on temporary leave. ("Green Light")
