An Amorphian (a true Cupid) is being chased by a very upset Zaybar (an amphibious humanoid) who's mad at him for causing his girlfriend to fall in love with someone else by emitting a love potion that effects everyone near him. During an incident when the Zaybar almost catches Cupid, his fear makes him emit the potion which ends up turning an iron fisted Judge into a lovable softy. Before the Judge sentences one of the most horrible criminals too lightly, the team must catch Cupid so he can reverse the spell. As they travel back to Chicago, Cupid creates lots of trouble! Meanwhile, Jonathan tries to talk Marni into re-creating the potion in the lab, hoping she will fall in love with him.
