Meghan is the wife of Victor. She is a stereotypical dumb blonde. She married Victor, for his money. Since Victor is wheel chair bound, she hooks up with Alan. She was also scared of losing her inheritance if Victor died on her watch. She used to take Victor wherever she went.
In "My Bodacious Vidalia", Alan manages to hook up with a dim-witted blonde named Meghan. She takes him home, where Alan finds that she has a 92-year old comatose husband named Victor. While Walden watches Victor and the couple hooks up in Alan's bedroom, Victor is thought to have passed away. They rush him back to Meghan's place, so his relatives won't cut her out of Victor's will for having an affair. On the ride back, Victor is found to be alive. Later, while Alan and Meghan are still hooking up, Alan finds Victor wide awake saying that he likes to watch them.
