Here are four theories that we found convincing
The 1st theory: Vecna will go after Will
Based on the concept of Vecna attacks people with traumatic experiences. Will is such an easy prey for him to attack, as he experienced many traumatic events, particularly in seasons one and two. In addition to the poster that shows Will while touching his neck and we know what that means.
The 2nd theory: Steve Harrington will die
Fans have agreed to two scenarios in which Steve could die. One is that he’s going to scarify himself for Nancy while she’s under Vecna’s control. The other is that what Robin feared will come true and he will get rabies because of being bitten by bats in the upside down. Hopefully neither of these theories will happen.
The 3rd theory: Eddie Manson is possibly Ten
In the last volume, we didn’t really know much about Eddie.There are many other reasons why fans believe the theory, regardless of how much Eddie and 010 actually look alike. 010 could have survived, as in the laboratory scene where 001 attacks the laboratory, his eyes were not blown like the others. Additionally, Eddie mentioned that when he was younger, his hair was buzzed. Also he’s always wearing a black watch where the 010 tattoo supposed to be.
The 4th theory: Characters who are placed in the bottom corners of the poster end up dead.
In the last season, Grigori and Billy are dead, who were placed in the bottom corners of the poster. Therefore, Jonathan and Argyle could end up dead. That’s a pretty convincing theory, but will it happen?
