I was confused by the physical response of the WLW to Kel as well. I thought maybe Kellhus had put a paralysis cant on him or something, but that was only because I couldn't think of any other logical reason he would be immobilized and bleeding from the ears. I had seen prior theories than Kelmomas would be central to stopping the WLW, but I am at a loss as to why he was unseen by the WLW in all his visions. This confrontation between Kellhus and the WLW was a source of great anxiety for me as a member of the "Kellhus is the savior" camp, and I was relieved to see him walk away from it, but I can't make sense of it yet.
