Shô appears shocked by the truth that Jellal lied about Erza, betraying them. As he falls into a state of confusion, Simon appears telling Shô what Erza just said is true, and he knew all along that Jellal has lied about Erza's betrayal. Everyone then agrees to work together to stop the Evil King's Incarnation's plans. As the team runs through the tower to stop Jellal, Simon tries to contact Wally and Millianna, but he is blocked. Gray questions Simon's trust as they travel. Simon tells him he knew skilled Mages like him and Juvia wouldn't die so easily, and he had faith Natsu wouldn't be defeated by Wally so easily.
