Welsey is, in my opinion, the best character in the Entire show. Doyle, he was great and everything, but in no way does he compare to Wes. Doyle played out his role, and that was that. As for if Wes and Doyle could "work" together. I think absolutely. It would just be one more person on their team. I think Wes and Doyle could have become very good friends because neither of them are the strongest or anything, but they would still be able to play out there part without effecting the other. But it happened the way it was suppose to.
