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.
And then Karlach, who also hates Mizora - for good reason - wants to take the sexy photo off his hands. Some humor I just don't get, I guess.
