Yeah, sadly I'm starting to think more and more that they'll leave him off the show for a week or two, someone will realize in the show that Glenn and Nicholas aren't back yet and then they'll go back to that alley.

I've already giving my thoughts on if he magically survives that. There have been some "unsurvivable" situations on this show that I at least was willing to give the writers a pass on, even though it was always a miracle far fetched escape.

This? No, there is no possible way they can have Glenn escape and not die and it be anywhere remotely believable. Whatever method they use to somehow enable him to survive, it is going to be nothing but bullshit.
thats pretty much how all tv shows work But you believe all the fantastic and dramatic and unlikely endings in sports they feed you far too often
