After the East Valley high school fight, multiple arrests were made, two of which included Cobra Kai's star student Hawk, and Miyagi-Do's star student, Robby. They were, stupidly, sent to the same juvenile hall, despite being rivals, even sleeping in the same room where a few other inmates slept. It wasn't a gender-exclusive juvenile hall, but males and females were still kept apart for obvious reasons, other than during meal and break times. The bell for break time rings as inmates file into various parts of the jail.
