Peter nods at Mr Stark's words and tries to just focus on breathing for a moment and ignore the urge to just scratch his arm raw. And then Gwen speaks. He gets the reference immediately and starts to giggle a little before his laughter starts to grow and he's suddenly coughing even worse but still laughing-who needs air anyway?

"Lost my-" cough. "Breath. Like my will to live" He says through coughs. "just push me back in there." He offers and is still choking on his laughter when Tony returns with help in tow. He tries to take in a deep breath and then can't help but scratch.

"Oh hey-" He coughs. "S'up Mr Stark?" What's up is that he brought help and somehow, some way she's like an RPG mage that knows cure or something because he sudden feels refreshed and not itchy or like he's dying of an asthma attack.
