The crew loves its needs however and Eddie seems to be giving off "joining the main cast vibes. He is still very expendable but it is a slight bummer to have another character introduced to die the very same season.If anyone gets killed it will be Eddie or Eleven. The town will never accept Eddie isn't the murderer, unless Eleven goes all Stephen King in front of everyone and gets blamed for everything as being the devil incarnate. I could see Eddie sacrificing himself to save everyone as he has no family and sees himself as a coward, so that would be his heroic act and he'd take the blame with himself to the grave.
0 chance eleven dies. Too many plot threads tied to her.
