If there was one thing that Peter knew it was Comic-con. He'd never been, well... okay no, that was a lie, he'd been, but he'd never been as himself, but in this place that didn't really seem to be a problem. So you know going through to see what it was all about when what was on the other side was a known quantity - that felt like a time when Peter could be sure that he could go through and actually survive this whole portal to an unknown world thing. And well, he'd heard there might be showers on the other side - and that was a possibility he could simply not pass up.
So he'd gone to check it out, wearing the costume because why not and then once he was there feeling like maybe the costume was not the greatest idea - considering just how many other vaguely spider-esk people there were in attendance. But maybe that was for the best, he was just one more Spider-man among many he blended better like this. Oh god he'd forgotten about fanart, yeah this was maybe not the greatest place in the world, and yet it was comfortable in a way - in it's familiarity.
And then there among the masses he saw her, he'd seen her around town a bit already since she arrived, the way he'd seen a lot of them around town since they arrived even if he hadn't been the one to find them, and even if they hadn't really spoken yet - but she bore the look of someone who was realizing that this whole thing was a lot bigger than any of them had realized before stepping through that door.
"Uh, hi." He said stepping up beside her where she was flipping through a comic book with some very familiar looking faces inside. "You're from... well through the door, right?" He asked her, just to be sure, because maybe it could be a very good cosplay, but his senses were telling him that she was exactly who he thought she was. "I'm Peter, I don't think we've actually had a chance to talk yet. But well.... safety in numbers?"
