Quotes from Rupert Grint movies and TV shows

Ron: Where's Hermione when you need her?

Ron: Follow the spiders? Follow the spiders?! Why couldn't it be "follow the butterflies"?

Gilderoy Lockhart: Hello! And who are you?
Ron: I'm Ron Weasley.
Lockhart: Really. And who-who am I?
Ron: Harry! Lockhart's memory charm backfired. He hasn't got a clue who he is!
Lockhart: This is an odd sort of place, isn't it. Do you live here?
Ron: No.
Lockhart: Really-? [Ron hits him on the head with a rock.].

Harry Potter: This is mental.
Hermione Granger: Completely mental.
Ron Weasley: The world's mental.

Ron Weasley: Hey!
Hermione Granger: You... Complete arse, Ronald Weasley! You show up here after weeks, and you say 'Hey'?

Ron Weasley: How long do you think she'll stay mad at me?
Harry Potter: Just keep talking about that little ball of light touching your heart, and she'll come round.

Ron Weasley: Don't expect me to get excited over another damn thing we need to find.

Ron Weasley: Do you think he knows? I mean, they're bits of his soul. The Horcruxes. Bits of him. When Dumbledore destroyed the ring and you destroyed Tom Riddle's diary all those years ago... He must've felt something, right? What I'm saying is, if we do this thing right, if we find the Horcruxes and begin to destroy them one by one... Won't he know he's being hunted?

Ron Weasley: Seems strange, mate. Dumbledore sends you off to find a load of Horcruxes, but doesn't bother to tell you how to destroy them. Doesn't that bother you?

Hermione Granger: We can't just stand here. Who's got an idea?
Ron Weasley: Don't ask us. You're the brilliant one!

Ron Weasley: That's my girlfriend, you numpty!

Ginny Weasley: He just asked Fleur Delacour to the ball. Actually he sort of screamed at her. It was a bit frightening.
Harry Potter: What did he do next?
Ron Weasley: What else? I ran for it!

[Ron unhappily looks at himself in the mirror. Harry walks in looking smart.]
Ron Weasley: What are those?
Harry Potter: My dress robes...
Ron Weasley: Those're all right! No lace, no dodgy little collar...
Harry Potter: Well, I expect yours are more traditional...
Ron Weasley: Traditional? They're ancient! I look like my great aunt Tessie! [Smells robe.] I smell like my great aunt Tessie! [Once again looks at himself in the mirror.] Murder me, Harry.

[Ron tells Harry that he warned him about the dragons.]
Harry Potter: Hagrid warned me about the dragons!
Ron Weasley: No! No! Remember... I told Hermione to tell you that Seamus told me that Dean was told by Parvari that Hagrid was looking for you. Seamus didn't really tell me anything. So it was really me all along! I thought you'd be able to figure it out from there.
Harry Potter: How could anybody figure that out? It's completely mental!

Professor McGonagall: Now, Mr. Weasley, put your right hand on my waist.
Ron: Whaaa?

Harry Potter: You're being stupid.
Ron Weasley: Yeah, that's me. Harry Potter's stupid friend!

Hermione Granger: Promise you'll write me this summer; both of you!
Ron Weasley: I won't; you KNOW I won't.
Hermione: Harry will; won't you?
Harry Potter: Yeah; every week!

Ron: Do you think we'll ever have a quiet year at Hogwarts?
Hermione: No!
Ron: Yeah, well, what's life without a few dragons?

Ron: Blimey dad, how far up are we?
Lucius Malfoy: Put it this way, if it rains you'll be the first to know!

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?
