In order to return Jean to the fold several years later, this storyline was retconned to reveal the existence of the cosmic Phoenix Force entity, which had created a duplicate body of Jean, believed itself to be Jean and acted in her place while the real Jean lay in a healing cocoon at the bottom of Jamaica Bay, where the Avengers and Fantastic Four would later discover her. This allowed Jean to be revived as a member of X-Factor. The extent to which the duplicate and Jean are separate entities depends on who is writing the character(s) at the time, some instances portraying them as inherently separate, while others demonstrate a shared consciousness.
