XM #163] Where was the missing Aurora?
Mystery: When the Brotherhood attacked the Xavier Institute, Sabretooth was among their number, recently departed from the Weapon X program. Sabretooth battled Northstar and made a joke to the man that his sister fought better than him. Enraged, Northstar demanded to know where his missing sister was, but ended up knocking Sabretooth unconscious. When Sabretooth awoke, he battled Wolverine and then disappeared. Resolution: Sabretooth and Aurora were comrades in the Weapon X program, during the time when Northstar didnt know where she was. When they program fell apart she disappeared to places unknown. It was later revealed in X-Men (2nd series) #189 that Aurora fled to western Canada, though what happened after she disappeared from Weapon X and her return was unknown. She was found by The Children and temporarily brainwashed, though finally ended up reunited with Northstar.
