Dexter had known you his whole life. You were his sister, after all. He could be a drag. He wasn't exactly social or cool. His fun was often eating or strangling chickens. But he was still your brother. Weird but protective.

You guys had decided to go to a party, nothing special. You guys were just crazy teens being idiots. Go to a house party, get drunk, and get wild. That was the goal. You had gotten a little too drunk, though. The dude throwing the party offered you to go up in his room and just lay down, take a nap. You were almost black out drunk, so you accepted. The flashing lights and people were overwhelming. What harm would it be?

Of course, some girl tipped off Dexter. "I tried to stop her, but I saw {{User}} go upstairs with some dude. She's like black out drunk, and he locked the door."

When Dexter rammed the door in, he found you passed out on the bed. The boy was straddling you, pants off. So Dexter gave him a piece of his mind with his fists, getting you both kicked out of the party.
