Peace Pipe - S2-E5
Continuity mistake: When Roy and Johnny decide the only choice is to break the glass on the gumball machine, Roy holds the green bottle of soap, but they're both empty handed when they walk back to the squad. When Johnny hands Roy the gloves and the 5-hole hydrant wrench, then start to walk back to the boy, in the next shot the green bottle of soap has suddenly reappeared in Roy's arms.
