Dean had a plan, but it was a very loose one. If anything, he just wanted to get out of his brother's sight in case he changed his mind. Perhaps the longer he stayed with the pack and talked amongst the others, the more they would have convinced him that it was something unavoidable.
It was hard for Dean; he had practically left not only his family but everyone he grew up with, and the town he had grown up in. Ironically, if it was up to him, he would have made it so all of the pack stayed in Ruin City, and now he was one of the first to leave.
Now he had entered a tier 2 city, where a new headquarters of NIRV had opened up. It was a large company that was opening more offices in more cities spread around the place.
