At the mansion, the Danger Room (the X-Men’s simulated reality training chamber) gains sentience, christens itself "Danger", assumes a humanoid form, and attacks the X-Men before leaving to kill Xavier. With Magneto's help, Xavier holds off Danger until the X-Men arrive. Danger flees, but not before revealing to Colossus that Xavier has known it to be sentient ever since he upgraded it. Colossus is especially offended by this because he had been held captive and experimented upon by Danger's ally, Ord of the Breakworld. Ashamed, Xavier tries to explain to them that by the time he realized what was happening, he could see no other course. The disgusted X-Men leave.
