Look he's doing it on command!
"Miles?!" Peter only just managed not to shout, at least they had enough music to kind of cover his shock when Miles revealed himself sitting there at the bar. "What are you doing here?" He hissed lowly shaking his head at the very idea that Miles was here even when presented with the very real proof that he was since here in front of him was Miles. "You can't be here, What are you doing?"
Okay yeah Peter knew that wasn't how this worked, you didn't just get to choose to come here and by the looks of it Miles was just as confused as he was about it all, but he still needed an answer as to how his tiny little spider protege had ended up here in this place.
"No, no this isn't New York." He agreed reaching out and putting his hands on Miles' shoulders just to further prove to himself that Miles was real and here and this wasn't just some fever dream induced by pizza fumes and alcohol from another dimension. "When did you get here? What happened, tell me everything."
