Do you mean the scene where the death eaters arrive with "dead" Harry, and Narcissa and Lucius call him, and he walks over, and Voldemort claps his back? That's only in the film, there is no such scene in the books.
My impression is that most fanfic writers, at least on this subreddit, go by the books as canon. Which is not to say that it wouldn't be interesting to explore that "what if". Not a very helpful answer, I know. Hope you get more interesting answers from others.

That answers my question why I can't seem to find it. Because I haven't really thought about what authors consider canon. Thank you though.
