The nikka totally ignoring the fact that Bran went into the past lol
95% of the board understands but him
1. Bloodraven took Bran into a vision of Winterfell 25-30 years in the past
2. Bran sees Hodor/Wylis when he was a kid
3. Bran wargs into Hodor in the present where his body still is
4. Somehow, Young Hodor/Wylis in the vision, where Bran's spirit is, gets connected
5. Young Hodor sees and feels his own death through this connection, goes crazy, becomes retarded
6. Young Hodor grows up into a man
7. Bran is born
8. Eventually he becomes the 40 year old Hodor and the past and present intersect again....this time he's on the other side of it as the old man holding the door about to die while watching himself as a kid shaking on the ground
It's not rocket science homie. It is very simple to understand. Very simple
