GRRM stated flat out that Benjen is not Coldhands because we have seen a ADWD manuscript page with Martin's and his editor's notes where that question was asked:
Leaf also stated that Coldhands was killed "a long time ago" and for a Child it seems odd that it would be a ranger who died fairly recently, given their lifespan.
Not that I trust that resounding "No" here any more than I trust Leaf's words. Plus, why else would the show pull out Benjen after 6 years (with the same actor to boot)? Questions, questions...
I almost didn't recognize Brutus though. For a moment I thought they swapped him for Faramir.
Because of course authors can not possibly lie in order for their books to not be ruined.
Assuming he was Coldhands, what the f would Martin say?
"Yeah you totally got me. It's Coldhands. I'm going to admit it and spoil my own book's twist, just because some reader guess right/asked, for millions of other fans, and those who may read in the future. You got me. The jig is up."
