Needed a post-credits scene of him being wheeled by Podrick to that bit Cersei liked looking out of, and being asked to be left alone. Then he stand up from his wheelchair, walks over to the window, pours himself a glass of wine, and says ‘well, that all worked out very nicely I think?’ and Littlefinger emerges from the shadows and says ‘Oh yes, very nicely indeed’ (in a Scottish accent) and then Bran hands him back the knife from the first episode, they shake hands, jaws drop and OUT.
