When Lisa, now aged 25, arrives, Del and Rodney are immediately shocked to discover that the scruffy girl they once knew has evolved into a pretty young woman.
The next day, Albert is trying out the new solarium to cure his hangover, and Del enters the flat with a bag of food for the date with Lisa.
As Rodney lies under the solarium, Albert talks about the time that he and Grandad fell out over the affection of Ada and never spoke to each other again.
Lisa tells the Trotter Brothers that she has some friends who run a hang gliding club, in which Del lies by saying he enjoys the activity.
Rodney tells Lisa privately that they should give Del a chance to hang glide as a surprise for his "46th" birthday.
The mention of the husband and wife to be who Del injured, in turn reminds Trigger to tell the others that Lisa's wedding to Andy, (to whom she has actually been engaged to for over a year), has been set.
Mike offers to open the Nag's Head early for a celebration drink, and Trigger and Albert join him.
