As dictator_duck said, we develop our headcanon together pretty much, so *beams!* I'm really, really glad those two cities worked. I'm not sure why I was drawn to Chicago for Nat, just that in my mental conception of it, it seemed...Nat-ish. So, yay! :D

Tokyo is waiting for me to find my action brain <.< but it's just...it's how we view Clint and Nat and their relationship, so I should really get on that. It entertains me (oh, Natasha. Poor, angry, lost, 'I got fired! so I'm going to hack into SHIELD' Natasha *facepalms at her*). And Clint is totally a geek - sniper! He spends a lot of his career thinking about things like wind-currents! It's a challenge and pleases his obsessive soul (because really, that's what geekdom is)

*beams!* Exceeeeellent. I'm developing it because I read some comics!snob being all "MCU!Natasha has to share comics!backstory, she cannot possibly have living parents or siblings, and being a criminal is too mundane" (because, you know, Natasha's words to Loki could never imply that she was a mercenary before Clint spared her, and organized crime never does anything interesting...) so I went "...Challenge accepted!" in my head.

So, aside from her full Russian name and comics!birthplace, I'm trying to work out a backstory using only what she says in canon as things I have to include. The full name is mostly because 'Alian' is (as far as I can tell from google) a highly obscure Hebrew name, so I've always quietly suspected he was Jewish, and so in this 'verse I'm running with it. Everything else, I'm just seeing what else fits and having lots of fun with with it. But all the research required, so it's a side-project.
