Natasha is born 1984 in the MCU. That information of her birth year is valid, it's on her file and was mentioned in Cap2. How they want to work the KGB in there? No idea. It's MCU, not real life. Guess they'll just make it so that a branch of the KGB exists for longer than it really did. But I'd like to see that file that came with the blu ray set anyway because I can't find a full picture of it anywhere. I want to know if there's a date on it when she joined S.H.I.E.L.D..
THAT'S the open question here. The timeline I mentioned does guesswork as far as I can see. They just say, she joined the KGB with 11 and then S.H.I.E.L.D. with 14 and provide The Avengers-movie as source, and again, that is just WRONG. In The Avengers there was no age or year mentioned anywhere, as of when she started working as a spy EXACTLY and when Clint brought her in. The only source I can imagine left is that file which is why I'd like to see it. But I refuse to buy a whole box set for that
. Especially since I own all the dvds and blu rays.
And frankly, so far I buy NEITHER of these guessed dates. 3 years of training a child, no matter how hard, are not NEARLY enough to make her the perfect spy she says she was AND commit all these supposed crimes she's trying to atone for...
