This is the first time in the entire series where the cat says Lister's first name. It is also the first time he calls Rimmer Rimsy.
Rimmer actually technically died at least three times, the third time being in 'Out of Time' although the other crew members don't know that it was when he was risking his life to bring them back when they were killed by their future selves.
The episode was released online a week early as part of the Dave Channel's "UK TV Play" service. The episode could be streamed online from the 27th of October.
