Walking Dead: Is Glenn Alive?

Impossible as it may seem, I would like to still think that Glenn is somehow still alive. I don't know how, and I really like him as a character - who has survived for six seasons so far. He has become a staple partner of Rick. It would suck to really see him go.

If you looked in the picture above, it seems like the space was too little for someone to actually be able to crawl and hide under - so this would probably be the last time we actually see Glenn alive. Flashbacks maybe, as it was mentioned that we would see Glenn again.

It is just defying logic for Glenn to survive this while being surrounded by the walkers, however - I did notice one thing. This gave me a minor hint that the body that was first eaten belongs to Nicholas instead of Glenn. This doesn't mean that Glenn will survive and to me that just seems really impossible.

Also, look here carefully - while Glenn was still moving his head left and right while someone's guts were being dugged out. He disappeared after the blink of an eye, that was right around the 34 minute mark into the show.

This happened right after a slight struggle and the walkers started to reach higher assumably for Glenn's body but they seemed to be grabbing nothing. Maybe I'm just paying to much attention to the details here but I would like solid evidence showing he's dead. Glenn is also not on Talking Dead isn't it?

I think the chances are quite slim and rather anti-climatic if Glenn survives. I like him too, but I keep having a bad feeling after he told Rick "Good luck, dumbass." - That was what was similar to what he said when he first met and helped Rick out.

Let me know your theories, sometimes I hate overthinking it but I just can't stop myself too.
