The Replayer
You return to what happened, looking for the moment things changed.
You replay the scene. The conversation. The thing you said or didn't say. You're not trying to torture yourself — you're trying to understand. If you can just find the exact moment things went wrong, maybe you can prevent it next time. But replay doesn't rewrite. The event is fixed. What you're actually doing is running a simulation, hoping it'll output a different answer than the one you already know. At some point the search for the turning point becomes the turning point. The question isn't what happened — it's what you do now that it has.
