Not Late

Waremis wasn't present when the twins checked their surroundings back outside the Wonderland. That's because he was hidden inside Sophia's Pocket Dimensional Realm. Sophia wasn't the only one to do it. Many of the experts, including the low levels ones, brought quite a few helpers in their own Pocket Dimensional Realms. It's just that none of them were revealed while everyone was nearby. 

Sophia took out the same Blue Ruler she used some time ago. After using her Divine Origin Energy on it, the ruler once again pointed in the direction of the tower in the distance. (Chapter 2635)

"It is definitely inside that tower, and there is no way they can't see the tower from where they are," said Sophia as she still looked toward Gratou and Flinyu. "I'm not sure if they are here for the same item, but they definitely won't just ignore the tower."
