Steve doesn't care if they're seen fighting. Steve cares if someone else tries to insert themselves into the fight. He can think of very few reasons that would happen, much less of ways for those to happen, but it's just about (not wholly, but close) the only scenario there's a problem for him.

At least the only weapons involved are Clint's knife, anyway, and yeah that simplifies a lot.

The question while they walk is fair, but it's another one of those things that makes him look at his own shit a little more than he necessarily enjoys. He doesn't flinch from the answer, dress it up or soften it at all, though. For all the same reason he didn't hold back much when they were sitting on Clint's kitchen floor.

"I miss feeling like there was a reason I was alive." The fight was just the thing filling that role since he woke up - and the thing he was good at.
