When Lee and Mark were checking out the perimeter, they find a walker that has been shot with a white arrow. Lee notes that it was most likely used by the St. Johns.
Two minutes later, Mark is shot from further up the fence by a white arrow.
Then the bandits start shooting at them, but they're using red arrows.
So is it possible that the St. Johns shot Mark?
Does anyone else think this theory is plausible?
If so, this'll make me even more pissed at the St. John brothers. I still kind of liked Andy, but Mark was one of my favourite characters, and if they shot him... *cracks knuckles*
