You keep on accusing me of thinking the correct answer is wrong.
I do not think that.
I was correcting this part of your answer, which you emphasized twice here.
It wasn't clear whether or not you were agreeing or disagreeing with what I'd already said. Especially when you were focusing more on making the mental states deep-seated.
Also, you seem to be saying in your latest post that we're arguing he's interested in them without the incest flaw. We are not saying this.
No, my previous post was clearly a question.
Granted it's been three versions since I played prior to this one, but for Billy to be interested in incest, and the "Eeew Gross" reaction is when he hasn't got that flaw from getting Mind Control, Sympathic Link powers and Insanity aura don't remove the "Eeew Gross" reaction for him.
I keep focusing on the "Eeew Gross" part, because that's what was the key part of the question being asked. Not whether or not there is incest, despite the clear genre tags and obvious lack of incest restoration patch.
In fact, looking back this started when you quoted the following "you can short circuit their feelings and make them horn on your character even if he says "ew gross""
That was clearly highlighting the temporary nature of Obsession and Nympomaniac mental states, which are temporary. Making them deep-seated, therefore permanent mental disorders, requires a percentage chance to go in favour of them becoming deep-seated. It is an exceptional condition to them being temporary, not the standard.
