Hermione Granger (Emma Watson)’s Timeline and Summary

Like Harry, Hermione is preparing to leave home for potentially a very long time. To that end, she wipes her parents' memories and removes all traces of herself from their lives. Heavy stuff.
She knows that they might have to leave for their Horcrux hunt in a hurry (say that five times fast), so she packs a magical bag filled with basically everything they could need. Ingenious.
Even so, the journey is hard, and Ron gets so frustrated that he leaves. Which is really difficult and heartbreaking for Hermione, since she and Ron have been crushing hard on each other for…well, a very long time.
Luckily, Ron ends up returning. Hermione isn't super quick to forgive his faithlessness, however.
But not to worry: Everyone is friends again by the end of the movie, and they've destroyed a Horcrux. And learned more about the Deathly Hallows, in large part thanks to Hermione's reading. Not bad for half a year's work, right?
