[1] In this episode, Fletcher is tasked by Grouty to replace a bottle of pills Harris stole.
Grouty responds by grabbing Harris' injured arm, causing him to scream in pain.
Harris told Grouty that he dropped the pills off the landing near to where Fletcher and Lukewarm were sitting at the time.
To make matters worse, Barrowclough discovers the pills that Harris stole are in Fletcher's mug, although he does not say anything about it.
It turns out that Grouty is in charge of the swimming pool, in spite of the fact that Slade Prison does not have one.
To add insult to injury, Fletcher returns to his cell that evening to find Godber reading Mandingo.
Mackay suspects the men are up to no good and catches Fletcher with the pill box in his left hand.
Mackay warns Fletcher to be careful, as he nearly caught Harris stealing pills earlier that day.
Mackay also notes that the pills belonged to the Medical Officer but were for his dog's bad breath.
