I think that reznov is alive because the messages that you can find in Jason Hudson's and president John. F. Kennedy's email. The first one that Jason Hudson received is subjected "everything you now is wrong " the message is "you don't now me but I know Alex mason. You will learn to trust me. Everything changes on Friday" the second one is subjected "now you understand" the message is "it was by the hand of Nikita dragovich. This is the beginning. They are everywhere. Start at Vorkuta. Two escaped the breakout. You know one of them. The other just died. The third is subjected "a single step" which happens to be words of reznov at the beginning of the mission Vorkuta. The message is "echelon 5 21 0 8 18 15 14 7 21 16 23 9 14 23 0 6 18 4 Her name is Evelyn cross. The photo is for your eyes only. This will be my last letter for quite some time. When the time comes, you will now what to do. The third one is 3 years after his last message it is subjected "you have done well" the message is "please tell mason one last thing. This time it's freedom for both of us." which is connected to the words of reznov right after the mission Vorkuta, who else would have known those word besides those two? The letter to president John. F. Kennedy is subjected as "you have one day left" the message is "victory cannot be achieved without sacrifice" which is the same words reznov said at Vorkuta to mason. This is also a day before president Kennedy's assassination.
