It had been 3 days since Jackson's altercation with Lorne, and as much as he wanted to act like it hadn't, it had really effected him. Jackson had spent most of those 3 days in his room, save when he had to go and get food. The son of Area wanted to act all big and tough, but he couldn't. Some part of him had trusted Lorne, and when he had verbally lashed out at him, saying some definitely offensive things, it had really hurt him.
Jackson was laying on his bunk throwing a baseball in the air and catching it, thinking about how Lorne would somehow make a contest with this.
