In EP8, we learn why Troy was kicked out of the Alphas. He beat Dawe and Dawe couldn't eat properly for a while because his jaw hurt. Dawe himself said in EP8 that he has no chance of kicking Troy out of the gym. That means the Alphas have no physical chance against Troy until Caleb is there, and Chad won't beat his boyfriend.
This is a campus and it shouldn't be hard to figure out which dorm and room the MC lived in.
But something about Troy is strange, whether the MC beats Troy up or not. He seems to know the MC. The MC leaves very angry and Troy is scared. Again, it doesn't matter if the MC beat Troy up or not. I have a guess as to how Troy knows the MC. Take a look at the screenshots. Over the MC's right shoulder I suspect Tommy and over the left shoulder I suspect Troy.
I suspect this is why Tommy is angry at the MC and acting like an asshole as a DIK father. Troy witnessed the whole thing and we learned in this flashback that Tommy's friends just watched and didn't help him. This could have been the reason for Tommy's hatred of the Alphas, because Troy didn't help him in high school. Tommy told Rusty in EP5 that he is much more athletic than him and that he was not accepted by the Alphas. The reason could have been Troy or Chad.
Because of this high school experience, Troy might be afraid of the MC and Tommy knows what the MC is capable of, which he then tells Quinn, who gets a stun gun when Maya rubs the MC's tail.
Tommy's fight against the MC has a very symbolic aspect. Tommy is afraid that he has mistaken a CHICK MC and is not the guy from high school. That's why Tommy attacks the MC. Stupidly, it's him.
MC is 12 years old: the MC gets his guitar. He loves music.
MC is 15 years old: The incident at the high school.
MC is 18 years old: He comes to B&R. MC can only play guitar for one guy. Troy.
(Not recommended. First, it is not in the official guide and second, MC should not become gay because otherwise he can only play guitar for girls and he loves music. Ergo, the MC plays his guitar for people he loves. In the best case Troy is then his brother and in the worst case MC becomes gay.)
MC 21 years old: Yes, there will be a 21 years old MC. And why? MC goes to college at 18 and Maya's calendar shows 2017. But in EP6 Maya's calendar shows 2020. funny, exactly 3 years. 18+3=21. i have a rough idea what could happen. But I'm not writing this yet because there are too few clues.
