"Having a nice dinner," Natasha answers cheekily without missing a beat, her little smile shifting into something that looks more like a smirk. She doesn't mind that grimness. It would be more surprising if it wasn't there. She's so practiced at blending in that she doesn't tend to carry the same grimness. But someone that knows what to look for would doubtlessly realize that, even relaxed, she's always alert. And always armed.

But that doesn't mean they both don't deserve a night off. So she leans back in her seat a bit, eyes widening a little in a feigned look of innocence. "But if you're worried you might not be up for it, old man..." she lets the obvious bait trail off, mouth pulling to the side as she tries not to laugh.
