While Bascome is recovering in bed, he is still wearing the pants he had on when he was shot. The mud that was splashed on them is gone, but the pants couldn't have been taken off to be washed, and put back on because of the contraption that's on his wounded leg to help it heal.
While the Douglas brothers are standing in front of a building with a Borton & Co. sign, the shadow of a boom mic is on the wall at the left side of the screen.
Ching Lee knows Bascome can't use his wounded right arm, but she gives him a plate with a piece of steak on it.
