Yeah, I remembered later.
I don't think scenes from Episode 3 are something important right now because those pics could be something that didn't happen yet or...
Another crazy theory - but somehow very possible, if I may say so:
Let us say someone took pics of Chad under the shower. You know how in teen comedies big muscled men tend to be short in other departments? And when I said "someone", I thought about usual suspects: Quinn or Tommy.
Tbh, Tommy is the more probable culprit but let's do Quinn first (no, not in that way
name88).
So, Quinn took pics because she needs ammo for keeping Sage preoccupied with Chad's affair so she could do what she wants with HOTs. When she heard of or even saw MC's fight with AAAs, she sent Chad those pics and all of the Alphas would think of just one person who could do that because they saw him in the gym. Quinn would do that because she likes chaos or just for fun. I mean, she used shocker on MC just so she could mess up with Maya.
But Tommy is my favourite suspect here.
Tommy knows MC isn't afraid of jocks and Tommy has a big grudge with them. Taking pics of Chad and then spreading them on campus and sending them to him... Now, that would enrage Alphas! If Tommy was hidden during MC's fight with AAAs, he knows they'll accuse MC of taking those pics. And remember what Jacob said to MC after making up with Sage? "We'll keep your back"...
So, he'll stage attack of jocks on MC and DIKs will react and... We have a full-blown war and Tommy has a chance for revenge.
