Alt Shift X Trailer Summary

I really don't honestly know. I've stayed quiet on that because Benjen Stark is one of the great unsolved mysteries of Game of Thrones and has been so hotly debated for so long I just don't have a good feeling about any of the possible theories anymore.

It seems highly unlikely to me they'd just randomly pop him into a scene like that without a really damn good reason, don't you think? I mean... this guy's been gone through some serious times when he was sorely needed both for the Starks and the Night's Watch. The only good excuse I can think of is if he was captured by the wildlings for so long he ended up just staying with them but even that's pretty lame. 

Long ago I used to subscribe to the Coldhands=Benjen theory but have since read enough arguments against it to put me solidly back on the fence.

I really think Benjen probably died north of the wall but had with him some compelling or very important information about the Others.

Yes I do remember that notation bit from GRRM that seems to put the Coldhands theories to rest. That was probably the final straw for me and I've just forgotten.

And you're right, Benjen can't just forsake his vows the same way Jon is with undeath freeing him... unless Benjen is somehow undead/Other which doesn't seem likely either since they only seem to 'turn' babies into other White Walkers at least so far as we know.

i think that screenshot is fake or someone in one of the battle shots that just looks like him

He says someone sent it to him on Facebook. It's fake.
