In the Prisoner of Azkaban film, Harry tells Hermione something, and she replies that she doesn't understand.
Harry says this line in the Prisoner of Azkaban film, just moments before Buckbeak is going to descend on the cell where Sirius Black is being held captive:
You were right, Hermione. It wasn't my dad I saw earlier. It was... me. I saw myself conjuring the Patronus before. I knew I could do it this time, because... because I'd already done it. Does that make sense?
To which Hermione replies:
No. But I don't like flying.
However, Hermione had the Time-Turner the whole year, meaning she already saw the future several times (so in a way, she'd already seen/done what happened). Another example is when she heard the werewolf howl that got Lupin's (in his werewolf form) attention away from Snape, Sirius, Ron, Harry, and her Time-Turner self, when she was near the Whomping Willow. She then replicated this sound when she saw herself in the forest, to save the others (Harry, Ron, Snape, Sirius), and when throwing the rock at the vase at Hagrid's hut.
Why did she say that she didn't understand Harry or that it doesn't make sense if she had already seen the future many times because she went back in time many times with the Time-Turner, and thus "already doing or knowing her actions"?
