GOT 6×05 – Night’s King kills Three Eyed Raven

What if like the theories says bran is the night king. He looks at the three eyed raven for a second before he kills him there's a look of familiarity what if when the three eyed raven says "the time had come leave me" he's really talking to the night king bran

In the A Song of Ice and Fire novels, the bird is a three-eyed crow rather than a raven.

The crow is more active in Bran's dreams; it helps him wake from his coma.

The crow speaks to Bran, telling him it can teach him how to fly; other times, it screeches the words "fly or die".

When Bran finally meets him in the cave beyond the Wall, the three-eyed crow is revealed to be a pale, skeletal man in rotted black clothing in a weirwood throne of tangled roots.

His skin is white, aside from a red blotch on his neck and cheek.

He has fine, white hair – long enough to reach the earthen floor.

He is missing one eye, while the other is red.

Weirwood roots surround the man and grow through his body, including his leg and his empty eye socket.

His voice is slow and dry, as if he had forgotten how to speak.

It is also implied that he was once a man of the Night's Watch, due to his tattered black cloak – which means that the "three-eyed crow" name is a double-meaning that was lost when the TV series chose to consistently refer to him as the "three-eyed raven".

Within the books, there are numerous details that indicate who the three-eyed crow was before he entered the cave, but only a few of them have made it into the television series.

The three-eyed crow tells Bran that he has many names, and his birth name is Brynden – hence the theory that he is Brynden "Bloodraven" Rivers, a legitimized bastard son of King Aegon IV Targaryen and former Lord Commander of the Night's Watch who was lost beyond the Wall.

Bloodraven lost one of his eyes years before being sent to the Wall, and the three-eyed crow's true form is indeed missing an eye, but in the television series the three-eyed raven still has both his eyes (similarly to the show portrayal of Euron Greyjoy).

It's not clear if this means that the theory is wrong, or if the writers simply decided not to address his identity.

Felt bad for 3 eyed raven

Voldemort, is that you?
