Harry Potter and the Half-Blood Prince (2009)

Hermione Granger: She's only interested in you because she thinks you're the Chosen One.
Harry Potter: But I AM the Chosen One.

Albus Dumbledore: Take my arm. That was fun. Most people vomit their first time.

Dumbledore: Oh, to be young, and to feel love's keen sting.

Hermione: Excuse me, I have to go and vomit.

Ron: [Talking about Lavender] All she wants to do is snog me. My lips are getting chapped. Look!
Harry: I'll take your word for it.

Hagrid: Seriously misunderstood creatures, spiders are. It's the eyes I reckon. They unnerve some folk.
Harry: Not to mention the pincers.

Arthur Weasley: Times like these, dark times, they do funny things to people. They can tear them apart.

Ron Weasley: I'm in love with her!
Harry Potter: Alright. Fine. You're in love with her. Have you ever actually met her?
Ron Weasley: No. Can you introduce me?

Harry Potter: Professor, you knew Voldemort. You were his teacher. What was he like?
Horace Slughorn: Dumbledore put you up to this, didn't he?

Albus Dumbledore: Once again, I must ask too much of you Harry.

Harry Potter: Did you know, sir? Then?
Albus Dumbledore: Did I know that I just met the most dangerous dark wizard of all time? No.

Albus Dumbledore: You must be wondering why I brought you here.
Harry Potter: Actually sir, after all these years I just sort of go with it.
