When the prisoner comes on Andy cooking breakfast, he is carrying a jacket. After Andy secures him to the tree, Andy gives him his jacket so the prisoner won't freeze.
When Barney is about to jump Andy thinking he's the escaped con, he gives Gomer his pistol to cover him while he sneaks up from behind. This is a needless act since Gomer, who's armed with a rifle, would have a better chance of shooting the convict with the rifle than Barney's pistol as the rifle would be more accurate from such a far distance.
When Andy offers the prisoner coffee, the prisoner grabs the coffee pot right off the fire. The pot should be hot to the touch.
