Synopsis:
Infinity Inc. creates a commercial to advertise for their services. After screening the resulting video, the members go their separate ways. Dr. Chapel tells Rick Tyler that she has found a way to remove the side-effects from Miraclo. Fury intends to tell Nuklon that she is pregnant, but they are interrupted by Wildcat who is jealous. Jade and Obsidian take Solomon Grundy home with them and learn that they are now part owners in a radio station. Mr. Bones calls Helix who are now under the influence of Dr. Love.

Skyman is visited by Jonni Thunder who claims that she has finally gotten away from the Thunderbolt. Jonni then passes out and the Thunderbolt emerges from her body to attack Skyman. He is forced to surrender when the Thunderbolt threatens to disfigure the unconscious body of Jonni.
