I already knew Dumbledore was going to die, and out of these, is surly snape being a double agent for dumbledore, because the chapter when it was reveled is also my favorite chapter, and it made me ship Snily
My opinion (based on the order theyre in on the post)
Tbh i wasnt too surprised, i didnt trust the "hes a spy for dumbledore" thing ngl
Shocking, but not exactly very major imo
The memories just increased my hate for him so it didnt change much (I'm not looking for a snape good or bad debate rn, but feel free to tell me your opinion)
I was really shocked by this, and it completely changed my perspective when i reread books 1 and 2
Very shocking, and changed my perspective of book 4
Just seemed like classic mcgonagall, and i didnt even question it lol
