So, my dumbass is replaying episode 1 and why did Troy even fight the jocks when they came to MC's dorm? Or did they just whoop his ass for fun? or did Troy care just enough that he wouldn't let the jocks take MC's guitar
They didn't come for the guitar. They just stole that as an extra. They came to kick the shit out of Troy.
Is what it looked like to me.
Part of me wonders if Troy not wanting a roommate was his awkward way of trying to protect them from jock bullying, with how far they seem to be going against Troy.
Troy is an ex-Jock, so unless his circumstances are like Chad's (i.e. the faculty kicked him out but the Alphas still like him), Troy's on the outer with the Jocks.
If Troy had some falling out with the Jocks to the extent that he was kicked out (or left), it's not hard to believe that Dawe and his merry men would like to make Troy's life hell.
So Dawe and his band of beefcakes went to stir some shit with Troy (figuratively speaking, if it was literally speaking it'd probably be Chad stirring Troy's shit while it's still in his ass, with his cock... ok... got side tracked there), Dawe and his homophobic hombres beat Troy up and took Fuckface's guitar as a bonus.
I don't think anyone knew about the guitar until they saw it when they were pounding on Troy's face.
Still, for the guitar to find it's way to Sage, via Chad, Dawe must have known that Chad would score points with Sage if he was to give her the guitar, so I'd expect Dawe would have told Chad what went down. That doesn't sit too well with the Chad/Troy theories, 'cause Chad would have been mad if the Alphas were beating on Troy (although he'd have to hide it, not wanting to be found out and all that...)
