- On a more positive front, Hermione has had a realization about the sword of Gryffindor and why it destroys Horcruxes: it absorbed venom from the basilisk that Harry killed back in the Chamber of Secrets.
- She shares her discovery with Harry, who is, like Hermione, pretty excited to have more knowledge about what destroys Horcruxes, and why.
- When Ron joins in on the convo, though, he isn't excited or happy. He's really unhappy, actually. He and Harry start arguing about the whole quest for Horcruxes, and Ron seems to blame Harry for the lack of progress they've up to that point.
- Harry, obviously, finds that all pretty hurtful and infuriating.
- In the end, Ron decides to leave, and he asks Hermione if she's coming.
- She doesn't want to, and Ron basically accuses her and Harry of being an item.
- He leaves. Hermione tries to run after him, but he's gone.
