Natasha can't help but smile a little at the way he immediately frowns. "It was more of a moonlighting situation than a full time thing." It's sort of nice to see that this Bucky - and it's still weird to think of him as another Bucky - is similarly minded. It had always been less about being an Avenger and more about helping out her and Steve.

She can't help but chuckle at his question about the skrulls. "It's a good question. The problem is that skrulls can only skim recent memories. So unless we have some past in common here, that won't work. I can cut my hand if you want. Their blood isn't red." Though of course, given that he doesn't seem to know about the skrull, she could just say anything and he'd have no way of knowing.

There's a pause after he asks how he died. Really, the best way for her to get through this is going to be by pretending that she's investigating a skrull. Something she can't pin her hopes on. "Gathering the infinity stones. You jumped off the cliff at Vormir. How about me?"
