I wonder if they are full or half brothers. The woman I assume is Joshuas mother seemed to have some disdain for Clive. Like maybe Clive is the bastard child of the archduke while Joshua is the true born child.

It seems to be becoming likely that Jill will be a later party member. She will likely be Shivas dominant. It mentioning that Joshua bestowed his blessing on Clive indicates that the party members will all be dominants who bestow their blessings on Clive when recruited after the defeat of their armies.

Joshua will end up being the final boss by pulling an origami from date a live by essentially being catatonic while Phoenix runs rampant. Or he will just be one of the final party members.

By the looks of it, Clive joined the iron kingdom after the fall of Rosaria to hunt Eikons who they see as heretics. Jill was probably captured and enslaved to the empire of Sanbreque as the dominant of Shiva. Or maybe she was a spy sent to assist the fall of Rosaria
