"Oh, I'm sorry, was I interrupting?" Peter replied and placed a hand over his chest, "Didn't realize that. Were you planning on doing something villainous before or after you listened?" Because really, who wore something like that who wasn't intending on being up to no good. It wasn't like she was that Batman guy he'd heard so many urban legends about.
Letting his hands drop to his sides he felt a little stupid, standing there, staring. Only she probably didn't see his eyes looking over her. Yay for masks, they were useful for more than just hiding your identity in the end. "I'll wait here though," he folded his arms, "Till you're done listening and then I guess...I'll stop you from whatever you might intend on doing."
He smiled, though the masked didn't show it and felt a little more confident, standing a little straighter.
