After murdering Courtney on Earth-616, Sat-Yr-9 takes on her identity. Sat-Yr-9 knew about Jamie Braddock's reality warping powers before anyone else (including Jamie himself), since she has already encountered Jamie's alternate reality counterpart. Sat-Yr-9 challenges Ross's coworker (and secret admirer) Nigel Frobisher to a high-stakes card game at the London Hellfire Club, and wins. Frobisher agrees to serve her, and she orders him to rescue the Earth-616 Jamie Braddock from Doc Croc, intending to use his powers as a living weapon against her adversaries. Sat-Yr-9 takes Kitty Pryde under her guidance, enrolling Kitty in the St. Searle's School for Young Ladies, and arranges a deal to save St. Searle's from bankruptcy. Sat-Yr-9 later unmasks herself, revealing to Brian that she murdered Courtney and has taken her place; he swears revenge on the impostor for the crime as she and Jamie leaves.
