Every time Hermione is seen crying, it's because of Ron. I don't ship Harry+Hermione, but I ALWAYS hated the idea of her and Ron. I love her character so much and think she deserves a better love story than the one she got.
But from that moment on, Hermione Granger became their friend. There are some things you can't share without ending up liking each other, and knocking out a twelve-foot mountain troll is one of them. Where the friendship began.
