I'm kind of split about Glenn being alive. It feels really silly that some small items like tin cans could distract that many zombies when the local noise of groans is so much louder than the can itself. But at the same time, I don't mind the character so I'm good for a few scenes with him in it.

even has a whole page on that notion. Red herring maybe?
