Bucky was still trying to navigate how he felt about all these alleged memories, and he wasn't doing a great job of that since his methods mostly consisted of deflection and distraction. So trying to talk about it other than an off the cuff comment was asking a lot. After he'd gone through a pretty heavy discussion with Natasha, he wasn't sure he wanted to do it again. It took a lot out of him, freaked him out, and he didn't like feeling that way. Who would? Best to keep it light and surface level, even though it was neither of those things and he knew it.
He might, in a moment of weakness, spill more of it to Tony. The torture, the weird old guy guy with the accent who injected him with something. Being strapped down. No, not today. Maybe not this week. Or ever.
Bucky met Tony's thoughtful gaze with a flirtatious grin. He really liked this guy. He was in trouble. "I think some frequent blessings would do the trick," he teased as he traced a finger along the side of the other man's jaw.
