The Walking Dead writers confirmed he was building a prison.I still say Abraham needs to be the next one on a Polaroid picture for that wall. I would say Morgan but I think they might have something going on with him soon. I am curious what he was welding when they last showed him? Maybe the crazy Morgan will get released and he is used against the Saviors. To make it more interesting, maybe crazy Morgan snaps in Alexandria and starts to clear and Carol is forced to deal with him.
