Bloodraven was messing with Jon’s head. This is after Thorne passed Jon Snow, and the other seven. Jon wanted to leave and go back to Winterfell. A strange voice told him not to go back, and Catelyn Tully won’t accept him.
One of Garth the Greens children is named Rowan, which is appearently a berry, I think this fact is more known among English speakers but I just discovered it, since Rowan berries are red in color, I wonder if she could be a red head and blue eyed woman, similar to Catelyn, Sansa and Danella, even Rose of the Red Lake could have red hair and blue eyes, is there a relevance to this look?
