Harry Potter and the Prisoner of Azkaban movie

Quotes are taken from the PoA movie. 

Ron: I'm warning you Hermione! You better keep that bloody beast of yours away from Scabbers or I'll turn it into a tea cozy!
Hermione: It's a cat Ronald! What do you expect! It's in his nature.
Ron: A cat? Is that what they told you? It looks more like a pig with hair if you ask me.
Hermione: That's rich! Coming from the owner of that smelly old shoebrush. It's all right Crookshanks. Just ignore the mean little boy.
(Harry sees them and smiles knowingly)
Harry: Hey guys. 
Ron: Harry!
Hermione: Oh, Harry! Hi. 

(At TLC)
Hermione: You know, Egyptians used to worship cats.
Ron: Yeah, along with the dung beetle. 

(In the Hogwarts Express)
Harry: I didn't mean to blow her up, I just . . . I lost control.
Ron: Brilliant!
Hermione: Honestly Ron, it's not funny! Harry was lucky not to be expelled.
Harry: I think I was lucky not to have been arrested actually.
Ron: I still think it's brilliant.
Hermione: Come on, everywhere else is full.
Ron: Who do you think that is?
Hermione: Professor R. J. Lupin.
Ron: Do you know everything? How is it she knows everything?
Hermione: It's on his suitcase, Ronald!
Ron: Oh. 

(Draco scene that uh, well, you'll see at the end why it's here. *wink wink*
Pansy: Does it hurt terribly Draco?
Draco: It comes and it goes. Still - I consider myself lucky. If hadn't been for Madame Pomprey, in another minute or two and I uh...could have lost my arm. 
Ron: Listen to the idiot. He's really laying it on thick isn't he?

(By the staircase)
Ginny: The fat lady...she's gone!
Ron: Serves her right. She was a terrible singer . . .
Hermione: That's not funny Ron!

(During Snape's DADA lesson)
Ron: When did she get here?? Did you see her come in?

(Standing by the barbwire fence, staring off at the Shrieking Shack)
Hermione: (coy) Have I mentioned that it's the most severely haunted building in Britain?
Ron: (grinning shyly) Twice, yeah. 
Hermione: (grinning shyly) Oh, yeah.
Hermione: Um, do you want to move a bit closer?
Ron: (slightly winded) Er, what? 
Hermione: (embarrassed) Oh, to the- to the Shrieking Shack, I mean. 
Ron: (calms down) No, I'm - I'm fine where I am, thanks. 
Draco: Well well. Look who's here. You two shopping for your new dream home?

(Ron, talking to Harry about Hermione walking out of Divination class)
Ron: She's gone mental. Hermione has gone mental. I mean, not that she always hasn't been mental, but it's just that now it out there for everyone to see.

(Outside the Three Broomsticks)
Ron: Oh! Look who it is...Madame Rosmerta. Ron fancies her!
Ron: That's not true. 

(In Divination class)
Ron: That's a load of rubbish.
Ron: Where did you come from?
Hermione: Me? I've been here all this time.

(Outside, courtyard)
Hermione: Beautiful day.
Ron: Gorgeous. Unless of course you've been ripped to pieces.
Harry: Ripped to pieces? What are you talking about?
Hermione: Ronald, has lost his rat.
Ron: I haven't lost anything! Your cat killed him!
Hermione: Rubbish!
Ron: Harry, you've seen the way that blood thirsty beast of hers is always lurking about. Scabbers is gone!
Hermione: Well then maybe you should learn to take better care of your pets!
Ron: Your cat killed him!
Hermione: Did not!
Ron: Did!
Hermione: Didn't!

(In Hagrid's Hut)
Hermione: I think you owe someone an apology.
Ron: (turns around) Right, the next time I see Crookshanks, I'll let him know.
Hermione: I meant me.

(Outside the Whomping Willow)
Harry: No, no. Don't worry guys. It's fine. I'll stay.
Hermione: You go. I'll stay.
Harry: You ok?
Ron: I'm fine. Go.
Hermione: (to Ron) Ow, That looks really painful.
Ron: It's sort of painful. They uh...might chop it.
Hermione: I'm sure Madame Pomprey will fix it
Ron: It's too late. It's ruined. Gonna have to be chopped off.
