It took a moment for Sam to realize that she was talking about that Strange dude though he had no idea why he would suggest telling people she was from Comic Con. That didn't even make sense. It wasn't like the public didn't know about the Avengers.
He was easily distracted by her comment about glowing though and he let out a little laugh. "Oh really now?" he said. "That sounds like something I need to see. Not here." Because she was right that she would probably scare people.
