Seriously that dumb Gaspal was too dumb to realize he's nothing without Ivona, there is no need to be a good summoner, you can contribute to something else as well to be recognised by the king.
Though the dumb Gaspal was someone that can't be saved anymore, even the cousin was absolute idiot as well. If only he use his intelligence to make money instead of clinging to a trash as Gaspal while manipulating Ivona while he's at it, I can see he becomes happier than the current situation. All in all, both only see the glory of Ivona and Claude and don't even bother to think their hard work for the achievement.
