Looking for specific Revenge of the Sith fic

Hey everyone. Really hoping someone can help. I can’t remember the title or the author. I do remember it took place during Revenge of the Sith on Mustafar. I believe Obi-wan and Anakin are about to duel. I can’t remember if Anakin has Force Choked Padme or not. I remember Artoo comes in and somehow knocks sense into Anakin.
