There was only one man that wore it well, and there was a reason he had been in it the longest. It wasn't just a costume, it was a symbol, and one that came with a lot of responsibility. Jasper, by far, wasn't used to being the person anyone looked up to--he didn't have it in him, he couldn't even keep himself from slipping up in this short conversation. How was he supposed to inspire anyone like that?
"Captain...Mr....Steve," Jasper stumbled around, none of that feeling right at the moment until he landed on, "Sir. I would be honoured to be of assistance to you while you..." Whatever Cap meant he was going to be doing, Jasper had to encompass in a wide wave of his hand over the Captain and his bed. "But I'm no superhero. I'm a spy. I'm an agent of S.H.I.E.L.D., and not a very good one, admittedly--I got bit twice in one year. I'm barely figuring myself out again." And to take on a whole new identity like that, well, Jasper was never that good of an actor. That was just a hobby. But Captain America was saying 'who better?' to him, and that counted for something. Quite a bit, really. Enough to make a smile slip out unbidden, and Jasper could hear himself, "Do you really think I could?"
