Biography
Megan is the youngest child of the series' main character Vic Mackey.

Autism
Megan is diagnosed with autism in season 3, episode 12. Her older brother Matthew Mackey had already been diagnosed in season. There is relatively little focus on either child as a character, more attention is given to his family dealing with their autism. Season 4 features a storyline where their parents enter a class-action lawsuit against vaccine manufacturers due to the idea that thiomersal causes autism. One of their motivations for entering this lawsuit was to get money to pay for therapy, special education, etc. However this storyline quickly petered out; their parents want to enroll Megan in a clinical trial but only people without pending litigation are eligible. Their father procures a bunch of money illegally, allowing them to drop out of the lawsuit and enroll in the trial.
