In the "Rogue Cut" version of the film, Cerebro is being used in the future as a prison for Rogue, who is being experimented on by the Sentinels' human agents in the hope of finding a way to duplicate her ability to take powers from others, with Cerebro being used as the room's interior is shielded from external telepathic probes. Also, in 1973, Mystique returns to the mansion to get treatment for her wound as a cover for her real agenda to smash Cerebro, preventing Xavier from finding her again.
