Another Hint X May Be Reznov

[Pandaman5797]

Mr. Weaver --

Your sister Olga survived Stalin's Purge, but died in childbirth on

November 10, 1955. She had a daughter named Kristina who lives

today in Moscow.

I thought you should know.

-- X --

I know this is probably was posted and it is common knowledge that weaver knows about it,but I didn't come up with anything in the search bar...anyhow, this could point to X Being Reznov because Reznov was Russian and could have known Weaver's Sister...just a thought

[Phillips455]

actually john trent is reznov, x is someone else...

What if "X" is Evelyn Cross?

Then again that's something someone said on the COD Wikia, though that person's speculation sort of makes sense because an X is sometimes compared to a cross.
