In the previous two episodes, Norman Buntz (Dennis Franz) has one hand bandaged, the result of reattachment surgery for a finger removed by a perpetrator. At the start of this episode, his hands are unbandaged, and he assists other officers carrying an air conditioner.
Two episodes prior to this, Buntz had his little finger cut off by a loan shark and subsequently reattached. In the last episode, Buntz had a large bandage on his finger. In this one, the bandage is gone and there is no sign of a mark or scar of any kind on his finger.
Washington states that he had busted Layton at one point for car theft and that he later was responsible for helping Layton get on the police force. Car theft is a felony. It was previously stated in an earlier episode that an individual with a felony conviction couldn't apply to the police department.
