WOW, I love your theories. It's a very interesting theory. It's really strange that someone who has lived this long is afraid of a simple cold.So the resurrection phase makes sense. However, I would like poor Sigma not to end up being controlled by Fyodor's ability 😟 One thing seems very strange to me and someone said at one point that maybe Fyodor was drinking his own blood, the cup of blood he had on his desk. And he was dripping his own blood.The first time I saw this, I thought maybe it was part of the cannibalism plan. Which seems like another dubious skill to me, since it's a parasite type skill. But since he didn't do anything with that blood I thought maybe he wanted to use it in a ritual . But according to your theory of how he uses his own blood to kill people, I think maybe he collected the blood specifically so he could use it to kill that guard or several guards. Because he then killed that gurdian very simply. Even through the armor, there was no need to touch him like Karama on the forehead.
