 Kryten makes another admission – the doors to Lister's quarters aren't locked after all; he excluded them from the shutdown override in case anything happened.Lister goes off to steer the ship away from disaster, while Kochanski asks Kryten to repeat the squeak noises that the pipes make while repeatedly hitting his head with a spanner (which she had been doing earlier to the squeaking pipes).The episode overran by three minutes, and had to be cut down.
