I don't know to get it through that thick skull of yours that if you don't already know which options I've selected based on the information I've provided, one of the following must be true: 1) It's bugged; 2) You don't understand Ren'Py scene flow; or 3) The scene flow intentionally does not correspond in a sensible manner to the choices made.
