Existem poucas teorias para a visita e nenhuma delas é minha.
Teoria 1: visitando Dumbledore
The theory that makes the most sense is that Newt was visiting Dumbledore. People who have seen Fantastic Beasts and Where to Find Them in theaters will know that Dumbledore was Newt's teacher at Hogwarts. When Newt was expelled from Hogwarts, Dumbledore strongly opposed and fought against the decision, suggesting that there's some sort of kinship between them. Dumbledore also writes the forward [sic] to Newt's book, so maybe Newt's visit was in regard to that.
Teoria 2: Salvando o Bicuço
Another theory only gets stronger once you consider one of the key events of Prisoner of Azkaban: the execution of Buckbeak the hippogriff. It doesn't take a stretch of the imagination to think that Newt would take a special interest in Buckbeak. Newt is a lover of all animals, and Buckbeak's unfair sentence to death would draw his attention. This only makes more sense considering that Newt's mother was a breeder of hippogriffs; Newt had an early love of magical creatures. He could have been there to try and stop the execution, but he was unsuccessful.
Teoria 3: Apenas um ovo de páscoa ( Most Probably True )
