Fluttershy: Um, Rarity? Don't you think it's a little late in the day to be walking through the forest? It is... star-spider season, after all. Though, I'm sure you have a very good reason.
Rarity: Simply the most important reason I've ever had in my entire life!
Fluttershy: Oh, well then I'm happy to help. What is it?
Rarity: I've heard rumors that the Castle of the Two Sisters is filled with the most gorgeous of ancient tapestries in all of pony history! It pains me to think of those magnificent creations rotting away in those old ruins, totally unappreciated.
Fluttershy: I see...
Rarity: I require your help in borrowing one or two to bring back to the boutique where I can restore them. Maybe I'll even use the patterns as the inspiration for a new line!
Fluttershy: That does sound... very important.
Rarity: Yes, well, [clears throat] maybe not the most important thing in my entire life, but retro-ancient classical will be all the rage next season, so it's nothing to sneeze at. [sneezes]
Fluttershy: Um, are you sure you need those tapestries?
Rarity: But, of course. Although, I must admit these ruins are a fright. Just look at all the dirt everywhere! Ugh...
Fluttershy: [gasp] Angel!
Rarity: Goodness! It's practically an artistic treasure trove of ancient good taste! [sigh]
Fluttershy: Angel! Oh, you really shouldn't have run off like that. Ancient ruins are filled with all sorts of things that can hurt you! You could stub your toe, or, or trip on a loose stone... You have to be careful!
Spike: I don't think I'll need all these candles, Twilight. I was really only scared for a second.
Twilight Sparkle: Oh, these aren't for you, Spike. We're gonna be studying late into the night, and we're gonna need all the light we can get.
Rarity: [excited gasp] This one is perfect!
Fluttershy: Well, it certainly could use some restoration.
Rarity: Be a dear, fly up there and lift it off that hook?
Fluttershy: [grunts]
Rarity: [calling out] Maybe from below?
[clattering and shuffling]
Fluttershy: Ow... I think I hurt my wing.
Rarity: Oh, my dear, I am so sorry! That tapestry is far too heavy. We'll just have to find a smaller one.
Fluttershy: Oh, of course.
Rarity: Where, pray tell, did you disappear to?
Fluttershy: What do you mean?
Rarity: While you were struggling under that fabric, the entire wall spun around! You must have activated a secret door.
Fluttershy: Oh, I'm sorry.
Rarity: I suppose these ruins are chock full of them.
Fluttershy: Really?
Rarity: Absolutely. We must use the utmost care as we—
Fluttershy and Rarity: [yelp]
Rarity: I'm starting to wonder if maybe this castle doesn't want my expertise!
Fluttershy: Oh dear. Angel? Rarity, have you seen him?
Rarity: I'm not sure he made the trip down with us, dear.
Fluttershy: Oh, goodness! We have to find him. An ancient castle is no place for a bunny. He could get hit by falling debris, or the floor could give out under him! Oh! He could be trapped in a dark place with no way out!
Rarity: [flatly] I can only imagine how that might feel. Hmm...
Rainbow Dash: Applejack, if you're scared, you can just admit it. You don't need to put your hoof around me.
Applejack: Uh, I'm over here.
Rainbow Dash: [scream]
Applejack: [scream]
Rainbow Dash and Applejack: [both screaming]
Rarity: [gasp]
Fluttershy: Rarity! What is it?
Rarity: I felt something... alive!
Fluttershy: [gasp] Angel!
[rattle, spin]
Rarity: Well, tapestries or no, I have had just about enough of secret passages, mysterious presences, and unappreciative castles! [echoes]
Fluttershy: But we can't leave now, not with Angel lost somewhere in this dangerous old castle! He could be trapped under a crumbling statue, or stuck high in a tower without food or water or any friends at all!
Angel: [munching]
Twilight Sparkle: Spike, you've got to hear this. [reading] I love to duck behind the paintings, and though the Hall of Hooves still gives her a bit of a fright, the trap door slide is Luna's favorite.
Spike: "Hall of Hooves"?
Twilight Sparkle: [reading] Soon the Organ to the Outside will be finished. I can hardly wait.
Spike: What's the "Organ to the Outside"?
Twilight Sparkle: [happily] I have no idea!
[organ music]
Applejack: You hear that?
Rainbow Dash: You mean, the creepy sound of a haunted pipe organ?
Applejack: Uh... maybe?
Rainbow Dash: [worried] I don't know what you're talking about!
[organ music, whinny]
Spike: Uh, Twilight? Did you hear something?
Twilight Sparkle: Oh, Spike. Quit being such a scaredy-dragon. This castle is thousands of years old, and half of it was destroyed by Nightmare Moon. Of course it makes strange sounds. It's practically falling apart!
Angel: [giggles]
Spike: Oh... kay.
Fluttershy: [calling] Angel! Angel!
Rarity: I'm sure we'll find him.
Fluttershy: Angel?
Rarity: [hysterical yelling]
Fluttershy: Did you find Angel? Is he okay?
Rarity: [gasp] They are perfect! No castle in its right mind could possibly object to my restoring such exquisite works of art.
Fluttershy: Oh! They're lovely, Rarity, but... I have to keep looking for Angel. Oh, I hope he doesn't think I've given up on him.
Rarity: I'm right behind you! Won't... [grunts] be... [grunts] a moment!
Applejack: Do you think there's a single room in this castle that isn't filled with terrifying things?
Rainbow Dash: Whoa! [nervous laughter] It's just old pony armor. What's the big deal?
Applejack: Yeah! It's not like it's gonna come to life or anything. Right?
[organ note]
Applejack: Huh?!
Rainbow Dash: [screams]
[organ chord]
Rarity: [yelps]
Fluttershy: [screams]
[organ chord]
[carrot platform spins]
[organ broken chord]
Applejack: Whoa-oa!
[lightning and thunder]
Applejack: [screams]
Rarity: Oh! [screams]
[more ominous organ music with strings]
[crash of thunder]
Rarity: [groans, spits] Now, you look here, castle! You are very old and very scary! But your wall art is in an atrocious state!
[wind whistling]
Rarity: And there is nothing you can do to keep me from my sacred task of restoration!
Rainbow Dash: Uh... Applejack? If you went back to Ponyville, that means I win, right?
[rattle, crash]
Rainbow Dash: [screaming]
Fluttershy: [calling] Rarity! I know hiding isn't really your sense of humor, but please let this be a joke!
[light tap]
[loud organ chord]
Fluttershy: [panicked screaming, panting]
Applejack: [screams] [echoing] Rainbow? Hello? I guess if I don't find you, I win by default, right?
Rarity: [grunts] [grumbles] Of all the castles in Equestria, this is by far the most ungrateful!
Rarity: Oof!
Fluttershy: [whispered yelling] Angel! Rarity! Oh... I hope you two are together.
[rock sliding]
Applejack: [yells]
Rainbow Dash: Haunted statues, creepy armor... Come on, castle! Is that all you got?
ApplejackFluttershyRainbow Dash, and Rarity: [all screaming]
Rainbow Dash: [screaming]
Fluttershy: [screaming]
Applejack: [screaming]
[Rarity]: Aah! Aaaah! I was only trying to restore ancient art! [muffled crying]
Fluttershy: [whimpering] [gasp] Angel?
Applejack: [grunting]
[distant thunder]
Twilight Sparkle: What in the world is that?!
Spike: Oh, you know. Probably just more strange sounds of this old castle falling apart!
Twilight Sparkle: No one likes sarcasm, Spike.
[Twilight's friends yelling and screaming]
Spike: What got into them?
Fluttershy: [grunting] It's okay, Angel! You're okay! You're okay!
Applejack: Yaaaaah! Shadows everywhere!
Rainbow Dash: [screaming]
Rarity: [crying]
Fluttershy: [sobbing] Aaangeeeeel!
Twilight Sparkle: Alright, everypony, stop!
Applejack: Twilight?
Fluttershy: Must... save... Ange—! ...Oh.
Rainbow Dash: Fluttershy? What are you doing here?
Rarity: She's with me...
[magic release]
Rarity: [gasps] Thank you.
Twilight Sparkle: Have you all spent the whole night running around, scaring each other?
Applejack: Well, that depends.
Twilight Sparkle: On what?
Rainbow Dash: On whether or not you're the Pony of Shadows.
Spike: What's... the Pony of Shadows?
Twilight Sparkle: Oh, that's just an old ponies' tale.
[organ music]
Spike: Then who's playing... that?
Twilight Sparkle: We're going to find out.
[ominous organ music continues]
[all gasp]
Twilight Sparkle: [whispered] The Pony of Shadows!
[organ player continues]
Pinkie Pie: Hey, you guys! Did you know I can totally play the organ? Because I didn't!
Pinkie Pie: Check it out!
[plays sports "Charge!" theme]
Rainbow DashYou're the Pony of Shadows?
Pinkie Pie: [continues playing light melody] The pony of what?
Twilight Sparkle: See? What'd I tell ya?
Applejack: I thought you went to ring the school bell all week!
Pinkie Pie: Oh, yeah! I only had to ring it for, like, five minutes! They said that was good enough! Eh, can't imagine why...
[bell ringing]
Pinkie Pie: So then, I decided to throw a "finish ringing the school bell" party! But I didn't have any bluebells, and you can't throw a "finish ringing the school bell" party without bluebells, so I went to Everfree Forest to pick some, but it started to get so chilly.
[plays happy organ music]
Pinkie Pie: I had to wrap myself up in the tarp I was gonna use to gather flowers, and then I saw Fluttershy and Rarity. But they went into the castle before I could invite them to my party. Luckily, I followed them inside so I could help you all with your party!
[stops playing]
Rarity: What party is that?
Pinkie Pie: Uh, the "everypony come to the scary old castle and hide from each other while I play the organ" party? [plays note]
[sproing, thud]
Pinkie Pie: Duh!
Rarity: I swear, this is going right back where I found it just as soon as I've returned it to its former glory.
Fluttershy: Now don't go running off again! Oh, I can't believe I was so frightened. Guess I let my imagination get the best of me.
Applejack: I think we all did.
Pinkie Pie: I always let my imagination run away from me! Then it comes back... with cake!
Twilight Sparkle: Well, it's good to know that whenever your imagination is getting away from you, a good friend can help you rein it in. And even though I didn't find anything out about the mysterious chest, I'm glad I was here to help all of you.
Rarity: You certainly did that, Twilight.
Rainbow Dash: Yeah! Why weren't you scared?
Twilight Sparkle: Reading Celestia's diary made it hard to be afraid, because I knew what it was like when she and Luna lived here. Knowing something about the past made it easier to deal with my problems in the present, even the scary ones.
[remarks of agreement]


For now, yes, but things can be repaired. Also, the fact that the organ and the secret passages were still working after 1,000 years and the books hadn't crumbled into dust means that there is probably magic on it that is maintaining it. Who knows? Now ponies are coming to visit it again, it might start rebuilding itself.
