Well according to some if you like the Scyvendli and Cnaüir in particular, you condone rape. As for any of his brood surviving, the odds are in favor of that. Will we get a Scyvendli hoard that is attached to the Consult? I'd say yes, but I'd never thought of that before. What I keep thinking about is how the Skin-Spies and Aurang befriended Cnaüir. Was that just to learn if the Dûnyain? The the most logical answer. Yet, the ending of Moe and Cnaüir's meeting in Kyudea is so vague and leaves many outcomes to be suggested. If Meppa is not the creation of Moe+Cnaüir, tell me what would screw with Kellhus's mind more than him seeing Cnaüir in TUC. Why wouldn't one of the Skin-Spies used Cnaüir? Cnaüir more than anyone is a threat to Kellhus. Its another reason I'm a firm believer in Moe+Cnaüir=Meppa. The Skin-Spies knew that Kellhus feared what Cnaüir knew about him and you think they'd use that to their advantage.
are hinting that the Consult could use a skin-spy to appear as Cnaiur to fuck with Kellhus head? that would be cool! i don't know if it has been explored, but has anyone considered that Moe's soul could have fled his body and traveled into one of the skin-spies in kyudea? that would be pretty neat. they have an empty slot for a soul and bodies capable of dunyain-level physical feats.
i'm not sure about the Scylvendi showing back up in a significant way. it's only been 19 years since they were crushed and Kellhus has been the military mind on watch the whole time. i wonder if Esmi's concern about the Scylvendi is foreshadowing or just decoy. could be that Kellhus has, to some degree, forcefully reorganized the tribes into a more hierarchical system, like he did with the Mandate. Tinnurit, could be really important in that scheme.
if using a chorae on a sorcerer near a soulless derived critter means the sorcerer's soul has an opportunity to inhabit the derived thingy, then Kellhus may have the WLW figured out. get stabbed by WLW. get choraed by Zeumi prince, jump ship to nearby skin-spy he's been keeping around just for this purpose, voila!
maybe Kellhus will have Proyas killed and replaced by a skin-spy (one he's reprogrammed), so Kellhus can even pretend to be dead and act like he's Proyas carrying on the martyred Warrior Prophet's great scheme. could be a real motivator for the troops. Kellhus-as-Proyas could even pretend that the WP miraculously gave him the metagnosis as a sign that they should complete the mission
could be Kellhus has replaced all kinds of people around him with turned skin-spies: Iyokus maybe, maybe Esmi is one, just programmed to think that it isn't a skin-spy, let's see how Esmi responds to a paradox
Saccarees and Sarl might work
