I just read more info about my new crush Black Widow on wiki saying that:
In The Ultimates 2, she's revealed as the traitor to the avengers and sided with The Liberators and was later killed by hawkeye after she got nanonites activated by Iron Man rendering her in a hospital..
If they make a movie about Black Widow's origin, I might be watching but this spoiler version I just said, I hope they won't make it.. I just don't wanna see my sexy heroine ending up like that.. <3333 Scarlett. omnomnomnomnom.
