It gets revealed that Senior Crow Shrike had a ghostly mentor that borrowed his body to train him in old fashioned Red Crow techniques through crooked means. Wren has noted that his father seems completely different now than he did before and he wouldn't be surprised if a completely different face showed up beneath his old mask. Maybe there's a conspiracy of Old Crow ghosts that has been quietly stealing the bodies of the next generation.
