Hey! To update you. I figured out. Not everyhting might be exact but it works to meet the priest.
You interact with the kings room once. Then you go to wizzy's room FIRST, interract with the corner 3 times, then ask about his relationships with the puppets and the king. (Idk of the other choices effect the route or nkt, i ddint click them)
then you go to knighter, do the same (table 3 times, relationships, king) then leave. You do the rest of the interactions with crownus's room, until jestyn gets mad.
You convince him NOT to follow you. Then when talking with butley, same. Relationships, what he thinks of the king.
Then when he attacks you it should trigger. If you already notice different dialogue with knighter it's all good.
