Corrected entry: In an attempt to stop Ackerman from finding Baxter's hooch when the cell is being inspected, Rimmer and Lister decide to drink the remaining bottles of hooch. Even if they thought they could drink the hooch bottles before Ackerman arrived to inspect, they still would have the empty bottles inside the cell with them, so drinking the hooch would have been completely ineffective in the long run. (00:13:05)
Corrected entry: When Rimmer and Lister discover Kryten has planted Baxter's hooch in their cell, the only solutions that they can come up with is emptying the bottles into the sink and toilet, before deciding to drink it. In S8 E6 Pete (Part 1), it is shown that their cell had a ceiling duct used to allow Bob the Skutter to give Lister his meal. They could have easily planted the hooch in the duct, but that isn't even considered. It is unlikely they would have forgotten about the duct given the limited amount of places in the cell that they could hide it. (00:12:40)
Correction: A search of their cell would likely also include a search of an easily accessible ventilation duct for contraband goods.
Corrected entry: In the previous episode, Baxter was changed into an ape using the time wand and wasn't changed back before it was destroyed; yet here he is back to normal.
Correction: Who said the time wand's effects are permanent?
Correction: An empty bottle isn't contraband, only its contents. They could have refilled them with water, minimising any scent of the hooch.
