`  :::::::Actually, you've commented thrice and I only twice, so to respond to the above: The films are all acknowledged as part of the same Marvel Cinematic Universe, which is different from completely separate, discrete films.   :::::::Re: ``has never not been referred to as Black Widow``: In debate and law, this is asking to other side to prove a negative, the corollary being, ``Prove she's not being referred to as Natasha Romanoff``.   :::::::We know her name in the Marvel Cinematic Universe is Natasha Romanoff. That doesn't change even if she's called Black Widow. So we can say Natasha Ramanoff with certainty, which is what an encyclopedia strives for.   :::::::However, I suggest a collaborative compromise. We can absolutely say with certainty that, ``Marvel press releases refer to Scarlett Johansson's character as Black Widow, though the filmmakers have not confirmed the film's character names.`` Is this a fair compromise that addresses both our needs?   `
