So... he's found out that he's the Spider-Man.
The web slinging hero of New York, just so happened to be the little guy he'd run into on his way to work, and now there's this weird feeling in the pit of his stomach. How does he go about it? How can he go about it? It's not a problem that he's a vigilante, but it's a problem that the job is so demanding. He must've known that when he put the mask on, but Peter's kind, the kind of guy that wants to help everybody at his own expense. And now he's rushing off to head towards a window he can crawl out through and jump off his terrace. Sid isn't going to stop him, but there's something that he wants to give him before he does go.
"Hold on a sec", he reaches for his hand, taking a hold of that small piece of him, he uses it as a bridge to close the gap between the two of them. Stepping forward in a fluid motion, he's standing a little closer than usual, leaning in a little more than he should.
"Before you save the day, I just wanted to give you this", and without a moment to lose, he's pressing his lips against the side of his masked cheek. Sid intentionally misses his mark as he kisses the spider, pulling back to look into the lens of the mask.
"Come back safe... and in one piece, preferably", his grip on his hand lessens, until it falls out of his grasp. He steps back, one foot at a time until he's back to where he was, just a moment before falling onto the couch and watching him stand there... lingering. He just smiles as he watches him stand besides himself, chuckling before he ducks out of the window and makes his 'grand exit'. The nerdy reply has him shaking his head gently.
"What am I gonna do with you?"
