For a moment he thinks maybe Vader won't notice him and also that's a little lame but at the same time probably a good thing. But then he does notice and Peter is forced to let out his breath, coughing as he does and covering his mouth because he doesn't really want 'coughed on Darth Vader' to be why he dies. As cool as that might look on a head stone. Never mind, he found out and there's a whole mix of emotions because meeting Darth Vader is super cool but also not awesome because he's dangerous and his Spideysense feels like it's practically vibrating like speaker at concert.

"My Species?" Of all the words he, Spider-man could have gone for as his first to Darth Vader that's what he chooses? Should he get down? There's no real point being up on the ceiling now, except that he likes the ceiling. "I wasn't... hiding..." He coughs and then moves to lower himself down to the ground again but not anywhere close to blocking the way. "I just like being on the wall... and holding my breath. It's-it's fun." He pauses, frowning at his own words. "Ceiling. That's-that's the ceiling, I know the difference."
