I think they're very funny and wacky I like them!! In French they speak in funny rich snob ways and they call each other "mon aîné"/"mon puiné" which means like elder brother/younger brother but "puiné" is an old-fashioned word nobody uses anymore and idk I just think it's funny. Also one of my friends has the joke-y headcanon that they're related to Lysandre in some ways since they're all royal blood and I think it'd be hilarious... like Sycamore thinks Lysandre doesn't want to go to Galar because he's prejudiced against galarian people but actually he doesn't want to risk running into his cringe far-removed cousins...
