If you’ve read HPMOR and watched Deathly Hallows, it will not be much of a surprise. However, it has not been explicitly stated by any of the material you’ve read/watched to date, so it is technically a spoiler.
That said, HPMOR does get better when you start getting all the canon in-jokes, so I would recommend consuming the originals at some point. They’re actually pretty good(even if the first two are basically kid’s novels).
