ok, I was able to make the shot, though the scene is extremely dark so it was quite difficult. I got to the next two scenes (stuff on the ground, and free move with the woman at the chair), and did one loop after doing some, uh, knife work. But I then got stuck again at the same woman scene, this time with apparently nothing to do. Maybe post a full walkthrough?
