Mia Lapierre, played by Krysten Ritter, is introduced in Dexter: Resurrection season 1, episode 4, Call Me Red, which aired on July 25, 2025. By day, she works as a wine sommelier, but she is also one of the serial killers who meets Dexter at Leon Prater's exclusive party for the city's most notorious murderers.

Others include Al Jolly 'Rapunzel' (Eric Stonestreet), Lowell 'The Tattoo Collector' (Neil Patrick Harris), and Gareth 'The Gemini Killer' (David Dastmalchian). However, unlike the other killers who prey on innocent people, Mia only goes after s*xual predators, leading Dex to think she follows a moral code like his. Dex is fascinated by Mia, who is labeled as Lady Vengeance by the media.

The two meet again in Central Park and bond over their shared experience of feeling homicidal urges during childhood. Mia opens up about the incident that sent her down this dark path—her younger sister, Hazel, was raped by one of their mother's boyfriends. She invites Dex to her house and asks him to join her in the shower, but he declines.

Their brief interaction hints that their bond will likely grow stronger in the upcoming episodes of Dexter: Resurrection season 1. Additionally, it may cause Dexter to reconsider his original plan to eliminate all the serial killers he encounters at the party.
