Be honest

You take a deep breath, reeling in your emotions. "It's because respects go both ways. I was striving hard to earn yours but realize that you don't respect me. That comes to a head when Amelie came last night."

Jan grins. "Oh, you feel that's a slight on your honor?"

You shake your head. "Others may think that way, but it's not as simple as that. If I really want to piss on my opponent's honor, I would really send whores to his room, the ones that you find in taverns outside. Maybe have them clean themselves, but still lowest of the lowest. Maybe the test is to be conducted in the barn or stable, to have him satisfy them like animals rutting in heat. Perhaps some witnessess as well, not too many, so that it wouldn't be embarassing. Of course, that exclude Lady Sonya, since the man wouldn't do it. Maybe one of her maids, to witness the pig the man truly is."

Jan rubs his beard in contemplation. "I find your descriptions a bit disturbing, but certainly worth implementing, if a few of them."

You roll your eyes in annoyance since you're clearly being cynical, but no sense in antagonizing the man. "Instead, you send me one of the Dukedom household's wenches. Still lowborne, but beyond peasantry, but beneath nobility. Why, considering the seemingly hostile tests that you gave me, this looks like a gesture of goodwill... and a way of telling me that you will still fail me in the end, but you will give my kingdom a favored treatment, especially a child is conceived as result of the union. You will tell me about it, maybe lording about my not being able to control my lust has caused a bastard to be born under your care, and after attemping to smash my dignity a few times, suggest that both of us can work together. In response to you keeping quiet about my secret and supporting me, I would assist your dukedom and the future succession by the legitimate heir. All that, and you don't have to marry of Sonya to me. Makes sense?"
