By your logic there is no harm in adding 'one scene' in regards to Shadow and its not 'rare' to find the necro scene, I found it in my second playthrough and so did many other people. You must have been playing a very certain way to not see it after 10 games (like how? lol).
To also counter your refusal statement he did add later on that its not on the table but not completely out of the question (Something along the lines of an animal on another character just not MC, which is fine with me as long as it includes Shadow).
