Well then to answer the first part, I didn't mean you shouldn't get the dialogue options, merely that they should be "acted out" after you select them in a manner appropriate to the character (determined by the actual tags most likely).
So the option you pick as The Red King and Sebille might be the same
*tell them you're not interested*
But King will actually deliver the line in his typical elitist jerkass way ("I have no such need of services from a slave!"), which is different from whatever Sebille would say, even after picking the same option. It allows the characters to express personality and individuality while still letting you determine their actions; you'd select WHAT they do, but HOW they do it varies according to them. Does that make sense?
