He hadn't considered that, that it would be different, or that he'd have to change his behavior now because with them both knowing, it wouldn't be fair. It especially wouldn't be fair to Bucky, because there was nothing he could get from the flirting beyond maybe momentary amusement that had the potential of later heartache.
It was a sobering sort of thought, when he realized. When he was fully aware that Bucky's smile didn't reach his eyes. It felt a little bit like a failure on his part, when Clint had made it a personal mission to get Bucky to smile more.
Great. Amazing. And an okay that reached forward instead of staying in the present. Because even if Bucky would be okay, he wasn't right now. "You tell her," he signed right back, frowning slightly. "I. We. Care. Don't go far." Still, Clint exhaled and dropped his hands to his side. "You need space," he said, and it wasn't quite a question. He wasn't always unobservant, if he had been no one would ever have given him the name of Hawkeye.
