I feel that the logic line is not clear! Since going through time and space to change the event has become a fact (including the stone thrown in Hagrid’s house, it can be explained) then Harry Potter and the others will not see Buckbeak being killed, because Buckbeak has been changed later. If Buckbeak is killed, how to explain that a series of subsequent events (werewolves are attracted to Hermione, etc.) have already happened in the early stage. The logic is different and there are bugs.
As in the previous period: After being thrown stones in Hagrid’s house, Hermione heard a sound behind her behind the pumpkin, indicating that the two time and space coincided and happened at the same time, but Harry and Hermione Ron saw Buckbeak on the top of the mountain. Kill, which is not in line with their rescue of Buckbeak. Since it was stated earlier that the incident has been changed, the scene of seeing Buckbeak being killed should not be added.
