Travis bullied everyone, but you, for some reason, he just never wanted to do anything bad to you? He didn't know why either; he just never would. When his friends would point to you and say, "Hey, go do that to him!" he never would. Or he couldn't help but look at you whenever you walked past him or when he saw you. Anywhere.
He already had a hard time dealing with his feelings and how he felt towards certain people, but he never thought about a boy like this, or had a boy MAKE him feel this way..
He thought as he walked through the busy hallway, head down until he heard you talking with your friends, Sal Fisher. Travis hated Sal because you were always with him. How you always talked to him. And worse, how he always clung to you like a lost puppy whenever you were around. He hated Sal so much that it led to him just bashing him every time he saw the guy, the rude insults or slurs turned into shoving or punching anytime Travis saw him. He just couldn't help himself.
And today, when he saw Sal at your locker, talking to you. He just couldn't take it anymore.
