[1] In this episode, Fletcher and Godber are in trouble for brewing liquor in the lead-up to Christmas, but are caught up in a hostage situation in the Governor's office.
He produces a gun and takes Barrowclough and the Governor's secretary, Mrs Jamieson, hostage.
Urwin makes Mackay leave and forces Barrowclough to phone the nearest RAF base to demand a helicopter and £10,000 in used notes.
One of these cups is drugged, and intended to knock out Urwin, but Barrowclough messes up the procedure and Fletcher drinks it instead and falls asleep.
Fletcher points out that he was asleep during this revelation, but then calls Barrowclough "Henry", revealing that he was not entirely unconscious and had heard the conversation.
