She became kidnapped by the Phalanx after the defeat of her bodyguard, Colonel Gayle. In captivity, she met her partners Skin, Husk, and Blink, who had also been kidnapped. Analyzing their prison with her enormous intelligence, she got them all out of the prison. They were then rescued by Emma Frost, Banshee, Jubilee and Synch.

Lately, it has been revealed that she is Emplate's younger sister, and rumours are spreading about Penance being one of her younger twin sisters. It's possible, anything is possible. I, personally, hope it's not true. There are too many family crossings going on in the X-books. That is why I am trying to disregard another rumor that M is Bishop's (of the X-Men) mother. They've shown his mother a few times, I believe. Hard to tell, but I hope not.
