Thats definitely glenn. He looks to be in the woods and has a look of struggle or sadness apon his face it doesn't look like he is beat up maybe it's hard to tell

 

Yeah, after watching the promo a few more times it's obvious that he's clearly crying. There's another scene which appears to be him walking through the woods looking at a severely chewed up walker corpse.

 

This site can be a little screwy at times, so this wouldn't surprise me.

 

You know; I retract my previous statements. This is actually Rick hand the a gun off to Michonne. It's not the Blender Glock.

 

So tell me how Nick both saw Rick plant the gun in the blender and was at the gate when they arrived in Alexandria?

 

That one got me too. Unless Aiden was out there, but I can't imagine those two knuckleheads splitting up. It would be too much of a stretch for the pair to be out playing circle jerk with their walker friend when they heard the RV, saw Rick plant the gun, then while Glen replaced the battery hustled back to ASZ in time to open the gate.

 

I know Trent Reznor's voice when I hear it LOL
