But did zero to address the current 'is he or isn't he' situation. An hour and a half and still no answer.
As said already, he's under contract for another season. Why do that if you kill him off now? Also, he's been seen (with pictures) filming scenes with "Jesus" who has not been introduced. Now, some say "well for a back story". If that's the case, then where is "Jesus" now? There's no mention of him in Alexandria to this date. Now granted, they did the same with Heath (no mention). But I can't see them going that route.
So, Glenn is alive. He will make it back. My bet is that it will be during the mid-season finale. And that will usher in the introduction of Negan as the Wolves plan their massive counterattack.
