Frankie eventually agrees to forgive Johnno for his affair as she felt life was too short to remain hostile towards the father of her children.

Her final words to him are: "For the first we met, we were standing at a bus stop in 1979, your cheeky grin, the white leather jacket, hair slicked back, Johnno Dean, who treats girls mean to keep them keen."
