Just thinking about how playfull/prankish Scott seems to be with his work (hoarding details and overturning expectations) and thinking about how much he loves the theme of hidden ignorance...
What if Sorweel is a decoy for both the Anasurimbors and the reader? Having identified the 1 individual with their face hidden by divine power, the holy family and the audience may be convinced that no other individual moves in the same way on the plate. Magician Bakker will have us all watching Sorweel's blade when Kellhus get's a knife in the back from Iyokus? Moe jr? Kayutas? I think it would be someone that we have not gotten an inner monologue of so far.
