1:"for the first time dumbledore was pleading"
what if it was really that he was pleading snape to go ahead and kill him?maybe he knew that snape wud find it v v difficult to kill him.so maybe he was asking/pleading snape not to spoil their plan and kill him 😳 (i noe its wierd but dumbledore being a man of brain........) 😳
2:we noe that dumbledore can operate without touching his wand!(i remember reading something like that in some chapter)maybe he had summoned his wand after snpe cast the killing curse on him n lifeted that spell he had cast on harry.(this is the wierdest thing in the wrold but still....)
oor else it can be that it was not really dumbledore who cast the spell on harry.what if someone else had done it n when dumbledore was supposed to be killed he lifeted the spell! 😆 😆 (i noe i am being stupid)
but these r my guesses only
i in no way am justifying snape bcoz i like dumbledore a 1000000000000 times more than snape.dumbledore is my fav character n in the next book if snape really is bad then......... 😡
