Thermoman reveals his double identity to Janet's parents, in an attempt to gain their favour, but her mother can't keep a secret.

Piers get a new Mercedes. George works hard to buy Janet a car and Arnie gets his powers back.

An old friend of Thermoman's takes over Piers' body and tries to put Thermoman out of the superhero business.

Our heroic couple find out that they're pregnant in this episode. As part of the pregnancy George endows Joyce with Ultronian powers, which she the uses to go about saving the day. The sub plot is Mrs. Raven convincing Piers that he is going to be on ""This is Your Life"", and uses this to milk all sorts of 'goodies' out of smarmy Dr Piers.

Shortly after they wed, janet goes into labor. The baby has super powers and can talk, which is normal for Thermian babies.
