I'm looking over the snippet and now that I've dumped in another idea, I don't remember which of the two options I'd settled on, but it was either early SHIELD (still Clint telling Natasha) or post-HYDRA (again Clint telling Natasha). Apparently my brain didn't go in the direction of Natasha telling Clint. Now want to go explore that...

But not today because I'm neck-deep into "Falcon whose name is death" and if I can finish that, I want to.
