Trevor had nodded in response to Clarence's question, but Zeran was there before he needed to call out.

"Er... Uh, I'm Trevor," he said in way of greeting and then stepped more out of the way should they wish to enter.

Thankfully none of the arriving Pokemon looked at all like creatures from his world, and Trevor was happy to find that he didn't automatically tense up like he was prone to do in close proximity to new Pokemon. He gave a little wave to Noemi and tilted his head to smile at Noemi's friend. The floating cloth though... He wasn't really sure what to make of that, but somewhat expected it was it's costume. Maybe for the same reason as Jute? Or maybe this Pokemon was just shy like the little one behind Noemi. It didn't really matter to Trevor though and he gave it a nod in greeting.
