Benny took the invitation - how often could a Pokémon sit on and be carried by their god? Of course he wouldn't pass on that opportunity. He made happy sounds as they went to where Michael and Niccia were. This was amazing and he waved to Kim when she looked in his direction.

"I don't know about any trauma, and I forgot I can ask now." He noticed how Niccia tensed up and turned to see why. When he saw Arceus with them, he too tensed up. This had to be about what Sparky had asked on his behalf. He nervously awaited what would happen next, wondering why Benny seemed so carefree.

Andy had returned Bear and Merlin to their Pokéballs and turned around with the intention to return to Frosiien, but seeing Arceus approach his nephew, he gestured to Kim, Frosiien and Gavin and made his way to there; it seemed like something important was going to happen and by the looks of it, his nephew could use some support. 

When Kim watched Benny sit [i]on[/i] Arceus her jaw dropped, but she waved back when he waved at her. When it was obvious Andy was going to join them, she got down on all fours. [i]"Maybe we should join them,"[/i] she suggested and went to Andy so she could walk behind him. Since Benny didn't give an indication something bad was happening, she didn't feel too worried about what was happening, but approaching their god was nerf-wracking in itself.
