Fight back!
The night before the incident, while Quinn was sound asleep waiting for the other two to return, Peter had been called out by the group of first years. They had added him as a friend on his communicator watch and was able to send a message whenever they wanted to call him.
That night, they had asked to meet outside of the dorm room building, five of the first years were standing outside including Earl.
"So I see it looks like your friends seem to still trust you and you managed to get on their team then?" Earl said as he lifted his hand to look at his watch. "Oh, I didn't I say to meet here at eight-thirty? it looks like you're a couple of minutes late."
Two of the first year's student then rushed over and grabbed Peter. One of them held his hand behind his back while the other held out his right hand.
"Two minutes late means two fingers I'm afraid." Earl then held one of Peter's fingers.
