Barring a Duez ex machina moment like; it’s really a dream, hallucination, Glenn falling through a manhole cover or being rescued by Howling Mad Murdock in a helicopter, its hard to see how he survives being immobilized under a dead body and surrounded on all sides by many dozens of walkers. I agree, but that is not what I was posting about. I was responding to the idea that the person in the body bag that Abraham sat with in the first episode could be Glenn - it couldn't be.
