In the events leading up her reappearance in "Weapon X" vol. 2, Aurora's mental health continues to deteriorate and she is later turned into a mind controlled agent of Weapon X. She also engages in an abusive relationship with the Weapon X director, Malcolm Colcord, who frequently beat her. Aurora manages to retaliate against her mind-control by creating a third personality that was unaffected by her situation. She attacks Colcord and manages to escape. In her next appearance, Aurora's mental state becomes unstable to the point that all her personalities agree that suicide is the best solution. However, she is stopped by the arrival of Northstar, who is under the control of the Children of the Vault, a mysterious group of newly emerged superhumans who seek to destroy mutants, viewing them to be their competition for dominance of the planet. One of the Children, Serafina, places the twins under their control, largely repairing Aurora's fragile psyche, boosting the twins' powers and altering them so that they can generate not only light when in contact with each other, but heat as well.
