"You already said that," Natasha points out with a smile. "I wasn't talking about work. But if that was your nice way of telling me to fuck off out of your personal life, it was well done." There's a sparkle of mischievous humor in her eyes that makes it clear she really means it. It's funny too that all of her extensive training never prepared her for this. Maybe she can forgive herself her missteps - first not looking at him at all, then looking too much. There was no happy middle ground.

Her expression shifts back into something like neutrality when he asks if she had been close to the other Bucky. Maybe he didn't - understand how Vormir worked. It's entirely possible Clint has never explained it thoroughly in this world. It had certainly taken her a while to make an account of it. For just a moment, she thinks about lying to him, but again draws the conclusion that it would be unforgivable.

"When you get the soul stone from Vormir, it's in exchange for the soul of someone you love." It's an answer from an oblique angle - he'll draw the conclusion that he draws, and he can ask her for more information if he really wants it.
