More than one question, looks like....
Jake went over the edge and stole the classic car the greasers had over at the autoshop at the time and tried to run down Tony, crashing the car in the stone wall near the steps by the fountain in Chapter 1. Jake fled the scene rather than be busted and hid in various places around the school, including in the Hobo's lot and under the Dorm. In doing so, he stopped taking his psyche meds and became delusional, and began dreaming up ways to take over the school.
I vote for a Hole fight. (for Norton).
We'll have to see how it goes with the Preps....First Derby, once he gets out of the Clinic, should try to attack Kurt and the Rockers, as he is pissed about Pinky. When this fails, and when Derby realizes how outnumbered he is, he will have to resolve his issues with Tad (also over Pinky) and make the move to re-unite the clique....
