Bucky doesn't exactly feel like their time has been wasted, but he is mad at how much time they could have had before everything went to shit. Maybe he wouldn't have wanted to go overseas to earn money if he and Steve had been serious with one another, he might have found another less risky way, and then he wouldn't be the broken mess that he is these days.

And maybe then Steve wouldn't have been bitten by some weird supernatural wolf creature and become half... whatever the hell these things really were.

"...shit timing, Steve."

Just saying.
