Bloodraven is the not the three eyed crow. I believe in the theory that the three-eyed crow and bloodraven are different. The three-eyed crow may be the combination of the spirits that live on in the weirwoods. So maybe Bloodraven is a part of the three-eyed crow but the three-eyed crow is not him.
The Book is vague so i took what matched my plot better.
In the show, Bran mentions that people talk to him like he is Bran, but instead he is the three-eyed raven now.
Yes, i should have written it as the three-eyed crow, as mentioned in the books, not the three-eyed raven.
Like I said, i got carried away while writing the last chapter. And I publish what I write without editing as I don't get enough time to do it. So the last chapter was a bit useless suspense yes. I am sorry.
And the Mountain is required for the future plot scenes in the war between the Lannisters and Starks.
