Major Story Arcs
Megan was initially hostile towards Laura before Laura revealed that Megan's kidnapping had actually happened, proving it by unsheathing her claws in front of her cousin, unaware that Megan had repressed those memories. Following this revelation, Megan formed a special bond with Laura and the two became best friends while attending school together, with Laura even adopting Megan's gothic dress sense. Laura eventually told Megan the whole truth about her past, abilities and the circumstances about her mother's death, including the effects of the Trigger Scent. Desmond (Facility agent and boyfriend of Megan's mother) put a dose of Trigger Scent in Debbie’s tea, because he wanted Laura to kill her aunt and Megan before returning her to the Facility. Unfortunately for Desmond, Megan accidentally spilled the tea over him and Debbie, causing Laura to go into a berserker rampage and kill him before turning her attention to Megan and Debbie. Megan quickly grabbed her mother and hid in the shower, washing all of the trigger scent off their bodies just as Laura was about to kill them, allowing Laura to regain her self control.
Laura sensed that Kimura was near and hid Megan and Debbie in the basement, hiding them from thermal sensors by showering them with freezing water from a burst pipe before killing all the soldiers of The Facility. However Laura was incapacitated by Kimura who broke her neck in the ensuing fight and took Laura into the basement to watch Megan and Debbie die. Kimura tortured the scared Megan but Laura managed to save her family by causing an explosion with Kimura still in the house and escaped with Megan and Debbie.
Laura gave her aunt and cousin a large amount of money and new identities to escape and create new lives for themselves, but told Megan that she couldn't go with them, not wishing to endanger them further and after a tearful separation, Megan and Debbie separated from Laura. Before leaving Megan gave her cousin Laura a necklace saying that she was going to give it to her when settling in.
Megan hasn't appeared since, though she has been mentioned by Laura and Kimura.
