When the X-Men are all captured on Krakoa (the Island That Walks Like a Man!), X convinces Moira’s kids to go rescue them. Immediately before they leave, he tells Gabriel that Scott and Alex are his brothers. The new kids rescue Scott, and Gabriel tells him that they’re brothers. Scott’s super beat up and his powers are broken, so the new kids leave him and go to rescue the rest of the captive X-Men—but instead, they all get killed.
