Harry Potter and the Half Blood Prince2009

[Harry Potter enters the Headmaster's office alone and watches everything, Minerva McGonagall enters to tell Harry]

Minerva McGonagall:
Potter... In light of what has happened. If you should have the need to talk to someone... You should know, Professor Dumbledore... You meant a great deal to him.

[Next scene, in the Astronomy Tower with Harry, Ron and Hermione]

Hermione Granger:
Do you think he would've done it? Draco.

Harry Potter:
No. No, he was lowering his wand. In the end, it was Snape. It was always Snape. I did nothing. [Harry gives the locket to Hermione] It's fake. Open it.

Hermione Granger:
[opens the locket and reads the message] "To the Dark Lord: I know I will be dead long before you read this but I want you to know that it was I who discovered your secret. I have stolen the real Horcrux and intend to destroy it as soon as I can. I face death in the hope that when you meet your match, you will be mortal once more. R.A.B." R.A.B.?

Harry Potter:
Don't know. But whoever they are, they have the real Horcrux. It means it was all a waste. All of it.

Hermione Granger:
Ron's okay with you, you know. You and Ginny. If I were you when he's around, I'd keep snogging to a minimum.

Harry Potter:
I'm not coming back, Hermione. I got to finish whatever Dumbledore started. And I don't know where that'll leave me, but I'll let you and Ron know where I am... when I can.

Hermione Granger:
I've always admired your courage, Harry. But sometimes, you can be really thick. You don't really think you're going to be able to find all those Horcruxes by yourself, do you? You need us, Harry.

Harry Potter:
I never realized how beautiful this place was.
