During the Extermination event that sent the time-displaced original X-Men back to their home era, a mysterious figure murdered Cable, the time-traveling mutant. As it turns out, a younger version of Cable killed his older self after because he felt the elder Cable had become too lax in his duties. Since then, the mutant nation of Krakoa has accepted the young Cable into its community, and the Summers family, including Cable’s father Cyclops, have welcomed him into their home. But Cable #4 reveals that Cable’s death was a bit more complicated than Extermination told. SPOILERS for Cable #4 by Gerry Duggan and Phil Noto follow.
