It's strange to see Steve almost of a height with him, and it makes his breath feel like it keeps getting arrested in his lungs. He wants this to be a good thing for Steve, that this health continues, because god knows there's nobody who deserves a miracle quite like Steve Rogers.

But he doesn't think that. Nothing comes without a price, and what if this doesn't stop? What if it keeps going until Steve is gigantic and misshapen? Or if it overloads his body and kills him like a fever burning through his veins?

"Right. Dog. I'll help."

Probably a bad idea, but he has to do something to help.
