The mind of Cable forcefully snaps back to the present day after he sends a desperate, telepathic message into the past to aid the time-lost X-Men squad. Unfortunately, his cosmic intervention is too late. In the past, Charles Xavier has tragically sacrificed his life to save Magneto from Legion, causing history to violently fracture.

A holographic transmission from Shi'ar Empress Lilandra confirms the worst: a massive chronological fracture in the M'Kraan Crystal is rapidly expanding, leaving the heroes on Earth with exactly one hour before their reality is wiped from existence. []

Gathered together at the Xavier Mansion, the X-Men spend their final moments finding peace and saying goodbye to one another. In these emotional final minutes, Cyclops and Jean Grey pull Cable aside to finally reveal the long-held truth that they were "Slim and Red," the parents who raised him in an alternate future timeline—only for Cable to reveal he had already known all along. After a passionate embrace between Cable and Domino, Professor X gathers his students one last time as the crystallization wave completely engulfs the planet, shattering the entire timeline into absolute non-existence.
