I guess so? They seemed to imply he's secretly sexually attracted to her, which I don't think is actually a thing in the game anymore - but I could be wrong. Ick.
My impression was that their relatioship is abusive, not that Wyll is into her. Mizora's voice actress did a great job, you can practically hear the glee in her voice whenever she gets to hurt him. So if they made a joke like that in the cartoon, then yeah, icky indeed. But very Larian.
