@Krimzonhawka Monarchs don't often add crowned heads as concubines unless it's someone who's actually their enemy. What do you mean, who knows if he has any value? His value (at this point) has nothing to do with his personal characteristics. It's political. He can be used to gain the allegiance of people in a piece of territory, or to threaten that territory's current overlords. If she doesn't know whether that has value, she should. As to making enemies, she's already done that by taking him even if she fails to use him.
But what makes it particularly annoying for me is I'll admit partly a matter of style. If she's going to self-indulgently ignore the political ramifications and make him a concubine, does it all have to be quite so . . . crass and disorganized? Does it have to be played like her main objective isn't even sexual satisfaction, but the petty enjoyment of humiliation? Really, as I say it feels like a hentai. And it makes her seem like a petty-ass gang leader who can't feel strong unless she's making someone else weak, not like a powerful queen, however ruthless. I wasn't expecting to like her at this point, but I was hoping for someone I could have a smidge of respect for. But this? What's being presented isn't a great queen, it's a wilful insecure schoolyard bully.
I guess it's supposed to be partly comedy at this point . . . but I can't tell for sure, and if someone's going to play sex slavery for yuks it'd be nice if they had jokes funny enough that I could tell they're jokes.
