I think Glenn is dead and will be discovered to have turned in a future episode where one of the cast (probably Rick) will have to stab/shoot him in the head.
Oh, man, I don’t want to see that. Glen has been there almost from the first, he joined them when they were living in that prison.
Another bad one was when the elderly white grandfather type was killed right in front of Rick and the others. Didn’t want him to die and not that horribly. Don’t remember the name of the bad guy who was running that town and he killed the elderly man.
Could you change your mind and let Glen live? (Is his spelling “Glen”, or “Glenn”?
