Evidence 4: The three-eyed raven has been keeping a close eye on Hodor all this time.
There must be a completely good reason that the three-eyed raven chose to watch Hodor and not anyone else.
Going back to Bran’s flashback scene, there was a point where Lyanna was on a horse and Hodor was talking. This was the when the three-eyed raven warns Bran not to stay in his visions too long. Again, there must be an explanation for that statement at that certain moment.
If the theory is true, everything certainly makes sense now. The the three-eyed raven warns Bran referencing what happened to Hodor.
