Well, that's the big question, Dawe is the reason Troy was kicked from the Jocks, but other then that there's nobody with a clear motive (not yet anyway) and we know the other photo's were probably Chad and Troy together.
People suggested Quinn or Vinny but it's really unclear why, who really gets ahead from increased hostilities between the Jocks and the DIK's? Maybe it's some tri-beta's getting 2 groups that normally harrass them to fight eachother...
Who really got any improvement from the situation? Funny enough that's Dawe... he's president of the Jocks now.
Troy got beat up for MC's guitar, he had a reason, but now his boyfriend Chad got hit hardest by losing presidency.
So Troy might have reasons but no results. Still if it was revenge for Troy it could have been Sarah and Melanie too, their involvement with the Chad/Troy situation remains unclear aswell.
It all starts with Quinn and Tommy. They want to party at DIK because they want to do drugs. You can read about it in the game. Rusty doesn't want to pay for drugs, but otherwise has no problem with them. Sage, on the other hand, has a problem with drugs. But the problem is that Sage is with Chad, who is the president of the Alphas. Ergo, Sage and Chad need to be separated.
Now Chad is caught by either Sarah, Melanie or Arieth in the gym making out with Troy. One of the three girls puts her panties in Chad's gym bag. (My money is on Melanie)
Because Sage was interested in the MC, Troy gets a black eye from Tommy and Tommy gives the guitar to Quinn. Quinn gives it to Chad, who gives it to Sage. The MC can only go to the DIKs to have a roof over his head. Since the MC is forced to go to Sage. At his initiation, he has to go to the HOTs to steal a slip. In the process, he also loses his clothes, and they belong to Quinn. Who called the Quinns and told them the MC was coming? Tommy. In EP1 and EP2, it is implied that the MC is meeting with Sage. Riona says that the MC is hitting on Sage, and Tommy says to fuck Sage.
The MC picks up his clothes from Sage and sees his guitar. This leads to Sage meeting up with the MC. Quinn and Tommy's plan seems to be working. If it weren't for Chad, who gets blackmailed and then attacks the MC. But who took the photos of the blackmailer? Dawe. He wants to be president. But why? Troy attacked Dawe once and defeated him. Chad probably had to kick Troy out, but Troy went to the gym anyway. A thorn in Dawe's side. He takes some pictures of Chad and some other pictures of Arieth that he got from Jamie's cell phone. Dawes sends the pictures to Chad and himself. In this way, he deflects any suspicion from himself. He thinks he's being clever. Oddly enough, he says this to Anthony, and Dawes has a cell phone in his hand.
Quinn probably doesn't have a problem with Dawes being the president of Alpha. She could very well control him. But when Chad attacks the MC and Jill informs Cathy, things get complicated. Because of Cathy, the Alphas are under surveillance. So Cathy has to leave so Quinn doesn't lose sales.
I assume the entire Quinn gang is involved in Cathy's mess. Riona, Camila, Heather, Misha, Nick and Tommy. I suspect that Tommy was pressured by Quinn. But that doesn't absolve Tommy of guilt. Heather will not have been actively involved, but she knew about it, just as she cared about Tommy. Camila or Misha were distracting Rusty. Misha's backpack is next to JB in the hallway outside the bathroom. It's her backpack because the same backpack is seen in EP8 at the last Free Roam event in Rusty's room. Quinn and Tommy disappear. They are both standing right next to Rusty's room where the safe is located. Tommy also knows the combination to the safe. Riona must have been instructed to pay attention and bring the laptop to Quinn and Tommy so he can lock it back up. But something goes wrong. Misha or Camila lock themselves in the bathroom, climb through the window and go to the mansion's biblitohek, where Nick is waiting with a USB flash drive. They post the Cathy Cluck, Rusty gets a message on his cell phone and sees the Cathy Cluck. Rusty looks for the laptop, opens the safe and leaves the picture crooked. He finds the laptop in the library. Nick either had to leave in a hurry and lost the USB stick or he hid the USB stick in the mysterious black BOX and can't find or open it later.
Everyone assumes that nothing will happen to Rusty because Rusty and Cathy are close.
The real question would be who does the USB stick belong to and what other information is on it. Maybe it's Quinn's USB stick with information about some people's dirty laundry. Quinn is organizing the HOT's for the prep party. But her influence doesn't reach that far, so she has to involve Sage under false pretenses. But because of the prep party, the DIKs aren't at her mansion. The Alphas have enough time to find the USB key. But it is in the black box.
Feel free to misunderstand it however you all want it to 
Okay.... i'll try to find a real topic now....
