"I didn't...but do now." Normally he would have smiled when the joke was on him, but they were technically on a mission. So his stone face remained set. Looking back ahead of them at the road, he continued.
"The only thing I care about is finding out who is abusing Erskine's work...and stopping them." He knew Clint would have at least looked at his file, and knew who that was. "He didn't make the serum for things like Fury...or the Hulk." Sure, Fury seemed to be a good man, but the serum was keeping him young. And Hulk was a whole other ordeal.
"You help me with this, Barton, and I'll owe you." He paused, gritting his teeth a little before continuing. "Anything you need, name it and I'm there." Then again, Clint did a lot of black ops missions....so Steve doubted he would ever be called on.
