but I'm saying snape would have known hermione had it.

and a time turner is such a powerful too, i doubt they would have given it to a third year.

and yes, hermione did mention that they couldnt change anything, but then the movies and even the last part of the book contradict that because harry is the one that produces the patronus. so he actually did interfere with what happened and that doesnt make sense in itself because the very first time they went through everything, harry wouldn't have been across the lake. if that makes sense. lol

like all the other stuff worked because they never interacted with their past selves (unlike in the book where the timelines interfered with each other, like when hermione threw the rock through the window) but harry doing the patronus and saving himself did interfere. harry even saw himself. lol.

i mean i know time travel is confusing but i thought that was a little odd.
