Thank you for the questions!
I do feel some amount of move-maker's remorse after the decision, particularly because Margot had always been loyal to me and really didn't deserve that. There's also the obvious possibility that Gustave, Oracle and Suzy run the game from here, the chance of which I had been aware of but may have underestimated.
But I expect I also would have felt regret at not making the decision. Obviously I don't have the insight into the Producer's views that you do, but I expect there would be at least some prominence of the perception that I was a less threatening version of Margot, or, with the rings as Producer knowledge, that I was playing Richie's game rather than my own after he had almost successfully blindsided me. This was my way of separating my game from Margot's and Richie's.
Even beyond Producer perception, I don't think I would have felt satisfied with my own game in just continuing the status quo. I wanted to play in a dynamic and exciting way, a game where I could work with anyone, pull off moves with multiple different people. Perhaps if I am not able to infiltrate Gustave, Suzy and Oracle and make my way to the end, then it is for me a sign of failure that means I was not meant to win this game.
But that brings me to the plan from here. It's tricky. My intention was to use the round to form closer bonds with Oracle and Suzy, but I cannot be confident that they would let go of Gustave. There's a possibility of me using Suzy's closeness with Richie against her, but I don't know if that would be convincing to Gustave at all, since I expect that he fully intends on trying to get me out.
As for not filling Richie in, that in large part came down to me wanting to foster a bond with Suzy. I wanted her to lead on whether to fill Richie in beforehand or not (and she never answered whether she wanted to tell him or not). I worried that if I had told Richie, he would have tried to get Suzy to vote for Oracle and that would reduce Suzy's trust in me.
Right now, I'm not very concerned about the fact that I didn't tell Richie, but I am still concerned that voting Margot out was not the right move there. Maybe I'm banking on Oracle freaking out about what Royal said and not wanting to do that again to me too. Maybe I'm banking on Suzy actually wanting an endgame with Richie open as an option and either that increasing my chances or increasing my chances of turning things on Suzy. Maybe I'm banking on unrealistic hope.
Time will tell, but I'd rather fail through action than inaction.
