I'm playing solo until my friend gets the game. Caddoc and I reached a point where he is no longer moving, after we killed the skeletons. We are boxed in, a wagon over the exit. I don't know where to go, what to do. Help please?

It hard to know where you are without a better description. Are you still in the prelude? Or are you in dyfed? If so, there are a number of places that have wagons, I would suggest running along the wall to see if any of the walls are actually doors.

Actually, I went back to my lact checkpoint and this time Caddoc reacted and moved the wagon. I guess it was just a glitch.
