The mental health of Sersi becomes worse with time. When she is framed for the murder of two policemen, Sersi snaps completely, destroying the Avengers mansion and fleeing to the Brooklyn Bridge. She used the Gann Josin bond to call Whitman to aid her and they battle the Avengers together – until the sight of her attacking Crystal enables the Black Knight to break the Gann Josin' s hold on him temporarily. Then it is revealed that it was Proctor who caused the Mahd W'yry disease in Sersi. Whitman also discovers that Proctor is an alternate universe counterpart of himself. Having been rejected by his own Sersi and twisted by the Gann Josin and his Ebony Blade's curse, Proctor now travels the multiverse with the aid of the Gatherers and a captured Watcher named Ute on a mission to kill the Sersi of every reality. Ultimately, in the battle of the Avengers against the Gatherers, Sersi slays Proctor with his own Ebony Blade, but is still afflicted by the madness Proctor instilled in her. A mortally injured Ute uses the last of his power to create a gateway into another universe where Sersi could be free of the madness and restore her mind. Whitman decides to leave with her, partly because he does not want to come between Crystal and her husband Quicksilver and partly because he feels responsible for what happened to Sersi.
