He and Sersi briefly reunite to return to the Marvel Universe, but something goes wrong along the way. Instead of returning to the Marvel universe's present, they end up in the 12th century and Whitman once again finds his spirit in the body of Sir Eobar Garrington. His consciousness is buried under Garrington's, however, and Sersi is forced to pass Garrington's soul onto the next plane (with his permission) to restore Whitman's consciousness. Whitman finds himself embroiled in a conflict with the evil mutant Apocalypse alongside his ancestor's best friend Bennet du Paris, the mutant who would later become Exodus. Apocalypse tries to get du Paris to kill his friend, but du Paris refuses. Judging him weak, Apocalypse puts du Paris in a state of suspended animation. Out of respect for his ancestor's friendship with du Paris, Whitman organizes an order of knights to guard du Paris' body, which they do through the ages until he is found and revived by Magneto. Sersi creates another portal, this time to the correct time period, and she and Whitman depart the 12th century.
