Quote #4
SCRIMGEOUR: "To Harry James Potter, I leave the Snitch he caught in his first Quidditch match at Hogwarts as a reminder of the rewards of perseverance and skill."
HARRY: Is that it, then?
SCRIMGEOUR: Not quite. Dumbledore left you a second bequest: The sword of Godric Gryffindor. Unfortunately, the sword of Gryffindor was not Dumbledore's to give away. As an important historical artifact, it belongs…
HERMIONE: …to Harry. It belongs to Harry. It came to him when he most needed it in the Chamber of Secrets.
SCRIMGEOUR: The sword may present itself to any worthy Gryffindor, Miss Granger. That does not make it that wizard's property. And in any event, the current whereabouts of the sword are unknown.
So, the sword of Gryffindor can present itself to people who are super brave like Harry, but unfortunately, it seems to be AWOL these days. And that's really too bad, since Harry could use that sword to destroy some Horcruxes.
Quote #5
RON: Going somewhere?
HARRY: Nobody else is going to die. Not for me.
RON: For you? You think Mad-Eye died for you? You think George took that curse for you? You may be the chosen one, mate, but this is a whole lot bigger than that. It's always been bigger than that.
HARRY: Come with me.
RON: And leave Hermione? Are you mad? We wouldn't last two days without her. Don't tell her I said that.
Harry has the reputation for being the brave one, but Ron is actually being pretty gutsy here, too. He (and several others, it seems) are willing to put their lives on the line to try to defeat Voldemort. Harry isn't comfortable with all that, but as Ron says here, they aren't really giving him an option.
Quote #6
RON: Do you know why I listen to that radio every night, do you? To make sure I don't hear Ginny's name, or Fred, or George, or Mom.
HARRY: You think I'm not listening too? You think I don't know how this feels?
RON: No, you don't know how it feels! Your parents are dead. You have no family.
Whoa, low blow, Ron. Ron is trying to imply that the whole Horcrux search doesn't have high stakes for Harry because he doesn't have a family to protect/worry about. Ron can't be in his right mind, because we know Harry is brave. In fact, Ron's lashing out seems like the cowardly behavior here, if you as us.
