Quote #4
LOCKET VOLDEMORT: I see your heart and it is mine. I see your dreams, Ronald Weasley, and I have seen your fears. Least loved by your mother, who craved a daughter. Least loved by the girl who prefers your friend.
HARRY: Ron, kill it!
LOCKET HARRY: We were better without you. Happier without you.
LOCKET HERMIONE: Who could love you compared to Harry Potter? What are you compared to the Chosen One?
HARRY: Ron, it's lying!
LOCKET HARRY: Your mother confessed she would prefer me as a son.
LOCKET HERMIONE: What woman would take you? You are nothing…nothing. Nothing compared to him.
So, when Harry opens the Horcrux so Ron can destroy it, it basically starts taunting Ron by verbalizing his worst fears. Among them? That Hermione and Harry really don't want him around and have lovey-type feelings for each other. These seem to have been the fears and angry thoughts that were behind Ron's drama with his BFFs. Luckily, he overcomes them and destroys the Horcrux.
Quote #5
DOBBY: Dobby has no master! Dobby is a free elf, and Dobby has come to save Harry Potter and his friends.
Oh, Dobby—we love him, because he's probably one of the most loyal friends Harry could ever have. And he's a house elf, which means he can Apparate in and out of Malfoy Manor to transport the prisoners (including Harry) out. A wizard definitely needs friends like that.
