People keep saying that Eddie won’t return in the next season, but I still have hope. One of the most fundamental things in movies and shows is the gun rule (I’m not sure what exactly it’s called), which is the rule that if you introduce a gun In the story it has to be used in some way. If something is introduced (like a gun, knife, a character, etc.) it has to be used and have a purpose. Almost every single story follows this. When The Hellfire Club is playing their final game in season 4, part of their storyline is that the character Kas rescues Vecna, and Vecna returns. And then Kas is never mentioned again. To mention and introduce such an important and fundamental character would make no sense, if they wouldn’t use him to further the plot. In my understanding (which is limited, I must admit) Kas is like a vampire lieutenant who serves Vecna, but ultimately ends up betraying Vecna. It would make so much sense for Eddie to “become” Kas. Just think about. Eddie returning as a vampire like creature, who serves Vecna, and the party having to fight him. It would be such a great storyline!
I don’t know if anything I said made sense, or if I’m just yapping away. You can also most definitely find someone who will explain this better. I really hope for this to be true, but you never know. It is after all just a theory.
