A/N: Hi! Well, I´ve seen quite a few ficsabout this challenge, and since I love Merlin I decided to try. Also because I´m completely useless at guessing, I thought I might be better at putting them :D
I used movies, TV series and books.
Well, good luck!
1: (Arthur and Merlin)
"Well it's no wonder you don't have any friends."
"Wow, only a true friend would be that truly honest!"
2: (Gaius and Merlin)
"See, there's a big difference between mostly dead, and all dead. Now, mostly dead: he's slightly alive. All dead: well, with all dead, there's usually only one thing that you can do."
"What's that?"
"Go through his clothes and look for loose change."
3: (Uther and Merlin)
"You are, without doubt, the worst sorcerer I've ever heard of."
"But you have heard of me."
4: (Merlin and Arthur)
"Sire, do you... like yourself?"
"What's not to like?"
5: (Vivian and Arthur)
"Artie, how do I look?"
"Like a beautiful blonde pineapple!"
6: (Arthur and Merlin)
"Do you know how to use that thing?"
"Yes. The pointy end goes into the other man."
7: (Merlin and Kilgarrah)
"Ah…my ancestors sent a little lizard to help me?"
"Hey!, dragon. DRAGON. Not lizard. I don´t do that tongue thing."
8: (Uther and Morgana)
"Now Morgana, let's not fight about this."
"No. Let's."
9: (Uther)
"You may think I´m here to make your lives a living hell. That´s just not true. I'd like to be your friend if you let me. So if there's anything that upsets you or makes you unhappy in any way... Don´t shoot your fat ass mouth off of me 'cause I don't give a shit! Now move it out!"
10: (Morgana, Lady Katrina, Uther)
"Oh, Gwen... what if Arthur and I don't... like each other?"
"Humph! As if that has anything to do with marriage. Do you suppose your father and I like each other?"
"Surely you must, a little?"
"Of course not!"
11: (Merlin)
You don't know me, but my name is Merlin Emrys and I love you.
12: (Uther and Valiant about Arthur)
"Whatever you do, don't kick him in the balls."
"I thought you said "anything goes"?"
"Anything goes, but he'll take it personal."
13: (Nimueh and Merlin)
: I can't do this.
: Why? We're a couple of good-lookin' sorcerers. It's natural.
14: (Uther)
"Sidhe, wildreoen, warlocks, they're all the same — best when cooked well."
15: (Morgana and Arthur)
"I love you."
"I know."
16: (Arthur and Uther)
"What happened to you, man? You used to be cool."
"I´m still cool!"
"Nah…you changed, man."
17: (Balinor and Hunith)
"Hold on! You're saying I might be Merlin's father, but he might be Gaius´ or Uther's?"
"Yes, and don't get self righteous with me."
18: (Gwen and Gaius)
"Gaius, Merlin´s missing. Can you find him?"
"Do you think I have him microchipped, or something?"
"Well, do you?"
"…Yeah, hang on..."
19: (Valiant and Arthur)
"Scared, Pendragon?"
"You wish."
20: (Merlin and Arthur)
"Arthur, believe me, there wasn't a day that went by where I didn't want to tell you, but Gaius thought it was too dangerous. Not just for me, but for anyone else who knew the truth."
"You didn't think I could handle it?"
"Can you?"
21: (Gwen and Merlin)
"Sorry, Merlin. Do you have a second?"
"A second what? Pair of underwear?"
22: (Uther)
"Who is Emrys? He's a criminal, that's who he is! A vigilante! A public menace!"
23: (Merlin)
(To Morgana) "You are beautiful." (To Gaius) "You are ugly." (To Uther)And you are…
