As much as Peter tries to hide his smile out of embarrassment, he completely fails at it. He's always been a bit of an open book, and now is no exception. He's just grateful right now that Tony can't see it.

Peter rubs his arm.

"Yeah, maybe," he finally manages to get out. "I think it'll be awhile before I catch up with you, though."

Peter taps the arc reactor, then thinks about the suit he wanted to make. He told Liz that he didn't feel like he could ever make anything up to snuff with Tony's tech and it should have felt like that now, especially after he showed him the nanotech. But now, he felt galvanized to try himself with whatever tools he found here.
