Ferris is here to make sure Ryner gets no gratification whatsoever, so it's all good.
As for Furoade vs Lucile, does that encounter (either directly or indirectly) ever have to happen? I'm under the impression that Lucile doesn't have any actual "plans" at all, and just watches over a king's safety until they break. He doesn't try to prevent the breaking from happening and just lets it run its course. Rather, one of the previous conversations revealed that he sees Sion as a true king if he can use Furoade's abilities for his own good.
