Finnick does look a lot different than when he'd first seen him. The injuries are mostly healed but it's the way he carries himself that's different now. There's still a hint of wariness around him and Bucky suspects that never goes away but he seems confident now and looser in his skin. He hands back the knife without fear, too, and Bucky thinks that goes a long way. He reaches for it and takes it back, tucking it into one of his many sheaths.

"I'm guessing you decided to trust the town a little, huh? Let me buy you a drink. It's the least I could do. Besides, I'm a little bereft of company."

Bucky is often bereft of company, being mostly a loner, but this is someone he thinks he can get along with, this Finnick, and having friends isn't such a terrible thing.
