an idea popped into my head while I was playing after the butler gave me some of "the good stuff", if you deny him the rest of the day off for a party (or whatever it was) enough times, it should be poisoned, but it shouldn't kill you immediately, after enough times of drinking it you (the king) should be visibly sick, and should get help from a doctor character or the Royal Adviser and there should be either a small chance that the antidote is sabotaged by the butler or there's a Y/N answer that, given your choice, will result in your getting better or early demise
