Like a snake that swallows itself, you're sometimes unsure of the beginning, middle and end with Red Dwarf, nothing is as it seems, in this episode, Dave Lister confronts his son, Dave Lister. According to a historic plotline, Lister is apparently his own father, we're not talking Bethlehem here, more a case of the father leaving the son in a cardboard box (hopefully recycled - the box, not the son).
As well as good video therapy between father and son, there were great belly laughs as the new computer replacing Holly, the gothic and assertive Pree, excellently played by Rebecca Blackstone, used the equivalent of predictive text to determine what the crew wanted before they could say it, negating the need for instruction. Until she took over everything - which might have been predicted - until Lister saved the day, which presumably made both father and son very proud.
There was a great running gag on Chinese Whispers, with vending machines varying each message, a little bit of bathos or pathos - Pree could have known which before they arose - and great ensemble playing.
The dark moments of One Foot In the Grave, nostalgia of Dads Army and farce of Fawlty Towers are sometimes matched by the boys of the Dwarf. Regrettably, Mrs Brown and her Boys have not yet appeared as extras, a shame, really, they would be as expendable as Pree, although not missed quite as much.
