Tomika was on the verge of an eating disorder
- On Dewey's first day of teaching, he inadvertently misses lunch; Ms. Mullins makes a point of telling him that the children have already eaten. He then asks the class if any of them has any food, and Tomika responds that she does. She opens her desk to reveal what looks like an entire lunch, including a sub sandwich and a packet of goldfish crackers. So Tomika clearly didn't eat lunch, and it's later revealed that she's self conscious about being fat. It's possible that she skipped lunch that day, and has perhaps done beforehand too, in order to try and lose weight.

The Broadway adaptation seems to imply this. There is a whole song in which they sing about him. That song ends with them wishing that they were more like him. They all knew he was up to something but didn't say anything because they liked having someone different at their school. Most teachers at Horace Green hate their jobs.
The song they sing in the broadway play seems to imply they are forced to act the way that they are and would be the cool teacher if they could. Horace Green closes down soon after the battle of the bands.
The parents decide to pull their kids out after their change of heart and have them attend a regular school. The teachers then decide to leave for other jobs. This combined with all the negative media coverage that would surely happen as a result of Dewey's ruse could easily doom the band. Mullins becomes the tin foil woman from the Netflix movie Let it Snow after she leaves Horace Green
Both are played Joan Cusack Mullins was married
Until the stress of her job caused a divorce which is why she has such a hard time letting her hair down. Patty will use her power to get Dewey arrested
