In the Pacific Ocean, Cable and Bishop investigate an intrusion into the remains of Greymalkin, which houses a dangerous "time displacement core". Within what they had thought an impenetrable base, they find Sinsear, who is attempting to return to his own time. Sinsear attacks, but he hits one of the core's containment walls and damages it, threatening an ever-expanding collapse of the timestream. Cable determines a temporal orb must be activated within the core, and intends to do so, at the cost of his own life. Sinsear stuns Cable, and sacrifices his own life to fix the timestream.
Back at the Xavier Institute, Cable discusses with Storm his fears that it their attempts to alter fate may be futile.
