They all entered while holding hands because only that way could they also 'move' to Crossworld. For some reason, it seemed that shaking hands with Ailord was the only way, like making a deal made all this feel more uncomfortable.
They all had the same reaction as Reyn, falling down and almost fainting, especially Teena who was still pale as if every drop of blood in her body had been drained. Her body wouldn't stop trembling, her hands were so cold, and her heart kept beating so fast it could be heard in her ears. For a while, she had to be guided by Glok so she wouldn't stagger and hit the walls due to her blurred vision.
Rako was the same, needing fresh air for a while because he wasn't ready to see such an absurd and strange sight. Especially seeing a creature made of wet hair that still managed to make his head hurt just thinking about it, even though it was only busy rolling waves.
