The aftermath of the battle is being discussed seriously by the kings. And it seems that Toni shows his ability well in the discussion. Harold must be glad that the future of his kingdom is safe with his sons taking charge.
As for Harold's other children, I heard that those who were influenced by the cult so much were punished. As for those who were not influenced much, Harold treat them differently. Since Fabio has been coronated as the king, there shouldn't be any more fight for the throne. So, they are either given the appropriate positions, or freed from the shackles of royalty as they will be free to do what they want.
But is Harold seriously do that? I don't think that's the case.
Even if they are free to do what they want, with the cult still at large, Harold shouldn't take the chance of letting his children to be entangled with the cult anymore. So, I guess they are still being watched.
