Twilight Sparkle

• "This is MY book! And I'm going to read it!"
• "Equestria, we have a problem."
• "But what if something else came up while we were gone? What if we were delayed getting back and I wasn't able to finish everything on that list?! What if we lost the list on the way to Ponyville and then couldn't remember which things we'd done and which things we hadn't done and then spent so much time trying to figure out what we hadn't done and what we had done that we ruin the entire celebration by not doing the one really IMPORTANT thing that we were SUPPOSED to do?!"
• " Okay, I get it, I need to work on my flying."
• "...why are you all looking at me like that...?"
• "I don't think I'm better than anypony!"
• "You realise this is information we could've used HOURS ago?!"
• "Oh, Rarity, you didn't have to do that! But... since you did...!"
• "I just need to be alone so I can study without a bunch of crazy ponies trying to make friends all the time!"
• "All the ponies in this town are crazy!"
• "Hang onto your Elements, girls. It's going to be a bumpy night."
• "Choosing not to choose isn't really a choice."

Rarity

• "Is it because you were insulted when I insulted your mane?"
• "Can we please stop running?!"
• "Opalescence, darling, I'm so sorry! I promise I'm not doing this on purpose! (puts out magic on horn) ...it wasn't me."
• "Oh, why, look, there's our friend Rarity going down in FLAMES! Isn't FRIENDSHIP MAGIC?!"
• "Does not infinity plus one. Hah."
• "Applejack! When you go big, you really go big!"
• "(after partaking in a partciularly dramatic song, helping Fluttershy up) I'm sorry, Fluttershy, but I'm afraid Applejack has made the better argument."
• "Fluttershy, sweetness, please come down. And do stop being a vampire bat."

Fluttershy

• "We have to figure out something. I don't know how much more of this Ponyville can take. I don't know how much more I can take!"

Rainbow Dash

• (acting 'casual', with sunglasses on) "'Sup."
• "I... LOVED IT! ... I mean... it was a'ight."
• "I ought'a press you into jerk cider!"
• "Is this some kind of cruel joke?"
• "Won't somepony PLEASE think of the cider?!"

Pinkie Pie

• "Okay, then. Make it 3:10 to Goof Off."
• (after an awful rendition of the Cloudsdale "anthem" by Spike) "NAAAAILED IIIT!"
• "This trip is gonna be so fun I love jumping up and down!"
• "Fruit bat round up, fruit bat round up!"
• "Suuuspiiiciooous! Hehe! It's pony signal time!"

Applejack

• "Well, all right, then! Let's go save a... tree."
• "Listen here, you rabid rhododendrons!"
• "Dear Princess Celestia, I wanted to share my thoughts with you. (clears throat) I didn't learn anythin'!"

Spike

• "Are you kidding?! Twilight can find a rule book for everything!"
• "You made a list? (laughs) That is so unlike you!"

Luna

• "Did you really expect me to sit idly by while they all basked in your precious light? There can only be ONE princess in Equestria, and that princess will be ME!"
• "We have graced your tiny village with our presence so that you may behold the real princess of the night!"
• "You were mistaken. But, I hope, not disappointed."

Celestia

• "Oh, dear sister. I am sorry."
• "Citizens of Equestria, it is no longer with a heavy heart, but with great joy, that I raise the summer sun. For this celebration now represents not the defeat of Nightmare Moon, but the return of my sister, Princess Luna."

Trixie

• "The GREAT and POWERFUL TRRRRIIXIIEE... needs some peanut butter crackers."

others

• • Granny Smith: What d'you say, Big Mac-a-do? Up for a little afternoon apple buckin'?
  • Big Mac: Uh... no.
• (Flim, seeing Applejack) "Well, if it isn't our most favourite Apple!"
• • Flam: Hypothetically--
  • Flam: --theoretically.
• • Rarity: Is that him, do you see him, Twilight, is he there?
  • Twilight: Uhh... I'm not sure.
  • Rarity: You don't suppose he decided not to come? Twilight, I don't see him! What if he doesn't arrive?! The whole festival will be a disaster! TWILIGHT, WHERE IS HE?!
• • Trenderhoof: Who... is... that?
  • Rarity: ...who? Applejack?
• • Trenderhoof: I once had an apple so rare, they thought it was extinct! I ate four of them.
  • Applejack: ...is that a fact.
• • Rarity: If there's one thing I love, it's hauling apples!
  • Trenderhoof: I'm growing fond of it myself.
  • Applejack: Maybe you two should try it sometime.
• • Twilight: What Pinkie meant to say was you were really great!
  • Pinkie: Wait, didn't I say that?
  • Rarity: Hardly!
  • Pinkie: YOU WERE GREEAAAT!
• • Applejack: Hey, Apple Bloom! You need anything? A snack? A hoof massage? Maybe a snack while having a hoof massage?
  • Sweetie Belle: That sounds delightful!
• • Scootaloo: Sweetie, no, you gotta sleep like Apple Bloom!
  • Sweetie Belle: How does she sleep?
  • Scootaloo: Like she does everything: with sass.
• • Crystal Guard Pony: A thousand pardons, O Great and Honourable Spike the Brave and Glorious.
  • Spike: Huh? Who the what now?
• • Spike: You never let anypony down. You don't know what it's like.
  • Twilight: Are you kidding? I've totally let ponies down. That's not the point.
• • Rarity: You look amazing, darling. They've really captured your regality.
  • Twilight: I suppose...
  • Rarity: Oh, don't be so modest! It's everypony's dream to someday wear a crown and have their coronation ceremony forever preserved in stained glass for all to see!
  • Rainbow Dash: I dunno if it's everypony's dream...
• • Celestia: No need for that now, Princess Twilight.
  • Twilight: Sorry.
  • Celestia: No need to apologise.
  • Twilight: Sorry!
• • Discord: Ladies, ladies! I'm innocent. Would I lie to you?
  • Mane 5: Yes!
  • Fluttershy: Um... maybe?
• • Discord: The rest of you could learn a lot about friendship from my dear friend Shutterfly here.
  • Fluttershy: Um, it's Fluttershy.
• • Celestia: Luna! I will not fight you. You must lower the moon! It is your duty!
  • Luna: Luna? I am... Nightmare Moon!
• • Twilight: I never should've agreed to come back here!
  • Spike: C'mon, Twilight. Discord may be reformed, but he's not that reformed. He's just trying to get under your skin.
  • Twilight: Well... it's working!
• • Rarity: How are we supposed to get to it?
  • Pinkie: (after falling down a flight of stairs) Take the staaairs, silly!
• • Rarity: Valiant effort on both your parts, but the tree remains in jeopardy.
  • Applejack: And I suppose you've got a better idea? ... That's what I thought.
  • Fluttershy: I know who would know what to do... but we sent her home.
• • Rarity: The truth of it is, Twilight, we're simply lost without you.
  • Rainbow: Yeah. Equestria may need its princess...
  • Fluttershy: ...but we need our friend.
• • Fluttershy: But our friendship remains. And if you want to remain friends, you'll stop thinking whatever it is you're thinking, and help us clean up!
  • Discord: Fine. But I don't do windows.
• Suri: I hope you realise how fortunate you are to have me as a mentor. NOW GET ME SOME COFFEE.
• • Rarity: Taking advantage of your friendship the way I did... how could you ever see past it?
  • Applejack: Yeah, you were pretty rotten.
  • Rainbow: Whoa, Applejack. I know your thing is honesty, but come on.
• • Fluttershy: Oh, I'm sure that if you let them know how special that particular apple is to you, they'll leave it alone.
  • Applejack: Yeah, right. Be my guest.
• • Rarity: I knew you wouldn't side with those... ICKY bats.
  • Fluttershy: They're not icky.
• • Pinkie Pie: You turned into a vampire pony!
  • Fluttershy: I tried to eat ponies?!
  • Pinkie Pie: Of course not!
  • Fluttershy: So I wasn't a vampire?
  • Pinkie Pie: Yes!
  • Fluttershy: Yes I was, or yes I wasn't?
  • Pinkie Pie: Yes, you were!
  • Fluttershy: But I didn't try and eat ponies?
  • Pinkie Pie: Yes!
  • Fluttershy: I did?!
  • Pinkie Pie: No!
  • Fluttershy: I'm confused...
  • Rarity: Me, too. And I was there.
