walk. "Helga" immediately tries to do away with the defenceless robot while out on their walk - using a variety of methods to dispose of him. None of these work and the robot turns the tables on his carer and eventually gets "Helga" encased in a concrete block. Fed up, "Helga" dumps the robot at the steps of a homeless shelter and runs away. Later, Tim spanks "Helga" as punishment for losing the robot when they go on walks. Graeme enters and tells off "Helga". Tim and Graeme demand an explanation from "Helga" as to why the robot keeps going missing. Bill, who's now dropped the accent and speaks in his normal voice, comments that the robot is growing up and they can't rule his life. A nostalgic Graeme goes to his computer to play their home movies featuring his robot son. These movies include such moments of Graeme shoving dozens of ice creams into the mouth of the robot and "Helga" subsequently being vomited on by the robot. The film ends with secret video that Graeme recorded of "Helga" dumping the robot at the shelter. Graeme then proudly announces that "Helga's" efforts to get rid of the robot were useless, as it is always programmed to come home. Bill inquires where the robot is now, and Graeme admits that he has no idea.

Tim demands that the robot get up to his room immediately, to which the robot replies "You said it, baldy". The sounds of them engaging in hanky panky are heard as Graeme and Tim lament over where they went wrong as parents. Helga chides the duo for having "got rid of that nice furry little bloke Bill"; for the robot is "ruining your life … and your ceiling!" (as it bangs and clunks around upstairs with its girlfriend) and Graeme's bid to put a stop to the robot's antics with "a jolly good talking-to!" with Helga's suggestion of setting up a good example. The robot comes back down and Tim tries to lay down the law. The robot treats Tim's dressing down with contempt, his interest only raising when Graeme
