Trivia since some of you people didn't get what's Siebold supposed to be, with his clothings and all:
He's an artful chef, yes, honestly! If you reached his Flood Chamber, his pre-battle dialogues hints on how cooking is related to Pokemon battle and how artful they are (I'm paraphrasing I can't remember his exact words). After the battle, he outright stated that cooking has taste that will disappear each time they were done, like Pokemon battle, to continue the cycle of this art, he asked us to keep on battling.
He's a chef, 5-star chef of the Kalos region slash a powerful trainer, an E4. Yeah, your husbando is a perfect material!
