Lex's journey to the camp was, for the lack of a better word, boring. A few times he ran into a few beasts, and just as he was preparing to give an explanation to avoid a fight, or perhaps even run away, the beasts would only nod at him and move away. How was he supposed to know that he was being identified as a mutated mole?
So in the end, the return ended up being him carrying the exhausted Barry through the forest for hours until he finally reached the camp. He hadn't had any time yet to think about his future plans, but this incident would surely affect them. Just as he was about to enter the camp though, Mary gave him an update about something happening at the Inn that put him in a foul mood.
