The following spoilers were wrong:
6.Fred duels a Death Eater during the battle, and then gets disarmed, and cornered by many other Death Eaters. This is likely what leads to his death.
8.Buckbeak, centaurs and house-elves don’t appear during the Battle.
9.Snape’s death will not take place in the Shrieking Shack, but in “a Crystal House” that can see the boathouse and the castle burning.
- it is the boathouse.
10.Voldemort slashes Snape’s throat open with the Elder Wand using Sectumsempra, before ordering Nagini to “finish him”.
- he doesnt use sectumsempra
13.Snape and Lily are not shown to be good friends, instead he admires her from afar.
20.After being struck with the Killing Curse, Voldemort turns to ash, and crumbles apart in a similar manner to Quirrell in Philosopher’s Stone.
23.Character ommisions:
* Mundungus Fletcher
