Megan was approached by a British Army Special Forces team, led by Captain Richard Ryan, to provide guidance about the area and search for any werewolves. However, when she learned that the soldiers were not there to help, Megan turned heel and betrayed them; telling them that werewolves were in the barn (which wasn't true) while letting a number of werewolves inside the house.
Megan reveals to Cooper that she, too, is a werewolf, and she had been suppressing her transformation for a long time; while a trio of werewolves appeared behind her. At that moment, the evil Megan sprouted fangs and yellow eyes and began her own transformation, but she was shot in her left eye. The shot did not kill Megan, as she resurfaced fully transformed (with her eye missing) and went after Wells, who was undergoing his own transformation. Wells sacrificed himself and blew up the entire house, killing Megan and other werewolves inside.
