How was harry potter able to see[despite the rain] during the Hufflepuff Quidditch match
Hermione put a water repellant spell on his glasses
Idk, it's a movie, so MOVIE MAGIC, or maybe just good eyesight for a guy with glasses
What smileyebbie said, Hermione put a water repellant spell on him. I don't remember if it was just his glasses, his face or his whole head
Ummm... because it's fiction.
