Rusty was humiliated. By some chick with what looked like a tattoo on her face. And she was calling him an animal? God, why did he ever leave his room? Seriously, now. Clearly, that was a huge mistake, and he needed to rectify that.
He looked at the ground, cheeks burning as he was washed over with shame, and he stood up, not replying to the blonde. He didn't need to invite more ridicule.
After all, he already had enough of that in his head.
