My favorite scene is from Harry Potter and the Prisoner of Azkaban where Fred and George give Harry the Marauder's Map, because this is the first time you get to see them in their own element and I thought it was funny when they kept finishing each other's sentences.
As I told in the wrong topic cause I wasn't concentrate, I think I'd like very much the moment when Dudley through his PS1 at the window if it was in the movie, even if this event is just told by Harry in a letter to Sirius in the second chapter of the 4th book.
I liked it where hermione says:" we should go to bed before any of you come up with another plan to get us killed, or worse expelled!"
But there are a lot scenes I liked but because I watched them a really long time ago I don't remember all of them🙄😊
