Morgan's absence from Alexandria in The Walking Dead has been explained by the events of Fear the Walking Dead season 7. As revealed in the season 8 trailer, Morgan has been a prisoner of the mysterious group PADRE since the end of season 7. It appears that this group is the reason why Morgan never returned to Virginia, despite the nuclear fallout in Texas and his group's desperate need for a new home. Had PADRE not been a threat, Morgan and his group would have made the journey to Alexandria. The seven-year time jump in season 8 further confirms that Morgan's return to Alexandria won't be happening anytime soon.
