I think that the thing that got hurt the most was his feelings. If he had been screaming in pain then something would have been done about it. The arm was in basically a "sling" the next day, it almost looked like a prop. I have no doubt that he tripped and fell down. His arm probably really hurt bad as well. But not enough to make such a big deal out of it. As a former "manager" than I would think he would have sucked it up and taken care of himself rather than whinig about it to everyone. I think Gideon's ego got hurt a lot more than his arm.
