The above picture is specifically from Harry Potter and the Prisoner of Azkaban when Fred and George Weasley first show Harry the Marauder’s Map.
The map, which shows the current location of every person in Hogwarts, displays the name Newt Scamander, who is somewhere inside the castle.
The names surrounding his are too difficult to make out, but that might not be important.
This could be nothing more than a fun easter egg — the real-life Fantastic Beasts book was published a few years before this movie came out — but that hasn’t stopped some fans from creating their own theories as to why Newt was visiting Hogwarts.
