Continuity mistake: When Glenda is talking to Tiffany on the phone at the hospital, when they say they need to get Tiffany in there somehow, the way their fingers are wrapped around their phone changes slightly between cuts. Noticeably, their pinky is suddenly about 2" higher. Then, in the next shot, they're back where they originally were.
Continuity mistake: When Lexy and Jake go to Lexy's house at the beginning, Lexy takes off her jacket. When she reveals Devon is there, too, and her mother freaks out, suddenly she's wearing her jacket again between cuts. She is then wearing or not wearing the jacket between cuts for the next series of shots.

Answer: They were blamed for the death of Jake's foster brother, which was deemed a terrible accident, and they were sent to the reform school as a punishment. Presumably, when they had to leave the reform school given what happened, they were instead given community service as punishment.
