Miles was just nodding to agree as he continued to take everything in. Gwen would have been right to ask- this was a little bit overwhelming for anyone with their senses, even someone from New York. So many new sights, smells, and even potential dangers. Still, Miles was more intrigued than anything else. "Like a space car lot?" He mused. "I wonder if they have those giant inflatable air guys- or maybe some space version of it" Or maybe the guys who held the signs!
Gwen asked about him and he looked a little surprised but shrugged. "Yeah...No, it's cool. I mean, it's a lot! But it's cool." He grinned, again trying to keep up that "cool" demeanor.
"So...um...what's a muggle?" Miles asked Sirius as Gwen went over to talk to the random alien, even though his eyes were on her and her strange miming the whole time. It was a show. He wondered if the poor guy knew what she was talking about. He got his answer when she came back.
"I don't think his name is really Bob." Miles muttered, but he was going to go along. "I also don't know if you really know that." He followed along anyway. Because, why not, right?
