Xavier mourns in silence the death of Thunderbird, the first of his X-Men to sacrifice himself.
Jean has come to share Xavier’s grief. Only a telepath could truly understand another telepath’s anguish.
From a distance, the X-Men are alerted to the cries of Colossus. He has discovered that someone had stolen Thunderbird’s body. Scott offers to help search for the missing body, but Proudstar’s family refuses the help. They wish the X-Men would leave them to mourn their son in peace.
Logan insists on tracking down the body and heads off by himself. Scott, Ororo and the rest of the X-Men follow him. Jean and Xavier remain behind. Jean had “caught a stray thought from the Proudstars” who suspected the thief was their younger son. Xavier wants Jean to kept that thought to herself, as the others will “learn those answers soon enough”.
While on the search, Nightcrawler, Colossus and Storm reminisce about their brief acquaintance with Proudstar. Meanwhile, Logan had caught up to Thunderbird’s younger brother James, who was preparing a funeral pyre for the brother he looked up to. Logan leaves James to lay his brother to rest and regroups with the rest of the X-Men.
Little do they know that James swears on his brother’s deathbed to take revenge on the X-Men.
