It was a sunny day in Ponyville until some Pegasi while other ponies were cleaning up branches and reattaching them to trees. Two ponies being Applejack and Rarity. After restoring a branch, Rarity used her magic to make the leaves look like ponies.

Rarity: Perfect.

Applejack used her lasso to tear off the branch.

Applejack: Just take the broken limbs down, Rarity. Don't y'all care about nothing other than prettifyin'?

Rarity: Somepony has to. You are making an absolute mess of the Town Square, Applejack.

Applejack: Yeah, well, the storm's gonna make an even bigger mess if we don't prune all these loose branches so they don't tumble down on anypony.

Rarity: I simply cannot imagine why the Pegasus ponies what schedule a dreadful downpour this evening and ruin what could have been a glorious sunny day.

The Pegasi got done setting up the clouds.

Applejack: (scoff) Think more practical-like, will ya? They accidentally skipped a scheduled sprinkle last week, (bucked a tree to make branches fall) so we need a doozy of a downpour to make up for it, is all.

It began to rain right there.

Rarity: Oh, no! My wonderfully styled mane shall be ruined!

Applejack: You should have hurried up and finished the job already!

Rarity began to freak out.

Rarity: It's coming down too fast! Help me!

Applejack looked around until she saw a bench.

Applejack: There! Hunker down to your heart's content whilst I finish things.

Rarity ran to the bench, but saw it had mud under it.

Rarity: Oh, no, no, no!

Applejack: What now?

Rarity: I'd prefer not to get my hooves muddy.

Applejack: (sigh) There is just no pleasin' you, is there? Everything's got to be just so.

Rarity: Oh, well, and how does muddying my hooves serve any useful purpose?

Applejack: Y'all wouldn't know useful if it came up and bit you.

Rarity: (chuckle) That doesn't even make any sense.

Applejack: Does so.

Rarity: Does not.

Applejack: Does so.

Rarity: Does not.

Applejack: Does so.

Rarity: Does not.

Applejack: Does so infinity. Ha!

Rarity: Does not infinity plus one. Ha!

They both gave each other deep glares.

Rarity: What say we go our separate ways before one of us says something she will regret?

Applejack: I reckon y'all are gonna say something you'll regret first.

Rarity: On the contrary, I believe it shall most certainly be you who says something you will regret first.

Applejack: I'm not sayin' anything!

Rarity: Nor am I!

Applejack: Y'all just be on your way, then.

Rarity: After you!

They both began to back away from each other until there was allowed Thunder crash made them scream and hug each other as the rain went down harder.

Rarity: Perhaps we should stick together for now and find some shelter.

Applejack: Uh-huh, perhaps we should... and fast.

Applejack was hiding under the muddy bench for shelter.

Applejack: Heh. Nice and dry under here, sorta.

Rarity: Oh! Unacceptable.

Twilight: Applejack! Rarity! Applejack! Rarity!

They looked to see they weren't too far from the Golden Oak Library and saw Twilight calling out to them.

Applejack/Rarity: Twilight?

Twilight: Come inside, girls, quick.

They ran to the library, but Applejack stopped right in front of the door.

Applejack: Whoa, Nellie. Is inside a tree really the best place to be in a lightning storm?

Twilight: It is if you have a magical lightning rod protecting your home like I do.

???: And it's been keeping me save for about a week now.

They turned to see Y/n walking in from the other room.

Rarity: Prince Y/n? What are you doing here?

Y/n: Twilight Sparkle here insisted on taking care of me while I heal from my burns. Now that they have healed, I was hoping to go home today.

Twilight: Actually, with this storm, I think it would be a better idea for you to stay here with us, your highness.

Y/n: Considering it's either that or I go out there and risk getting killed again... I'm weighing my options.

Twilight: You two can come on in.

Rarity: We are most grateful for your invitation.

Applejack: Thank you kindly for your hospitality.

She was about to walk in, but Rarity stopped her and directed Applejack's attention to her muddy hooves.

Rarity: Uh, do be a polite house guest and go wash up, please, won't you?

Applejack: (groan) If I got to spend one more second with that fussbucket Rarity today, I can't be held responsible for what I'm gonna do.

Y/n: What's this now?

Applejack: Uh, nothing. Nothing at all, Y/n.

Applejack went to wash her hooves.

Twilight: Some storm, huh? The Pegasus ponies sure have outdone themselves this time. I hope you and Applejack don't have any trouble getting home, Rarity.

Rarity: It may, indeed, be a problem.

Twilight: Well, you're all welcome to stay if need be. Spike is away in Canterlot on royal business.

Y/n: Lucky he gets leave.

Twilight: It's been nice having Y/n over and it could be better with you and Applejack. (gasp) We'll have a slumber party! I've always wanted one of those.

Y/n: I am still weighing my options.

Rarity: Oh, goodness. Uh, I do believe I have another engagement scheduled for this evening that completely slipped my mind until just now. (nervous chuckle) Oh, silly me.

Y/n: That's convenient.

Rarity: I can't possibly stay here all night... with Applejack.

Twilight levitate a book off the shelf and gave it to Rarity.

Rarity: "Slumber 101: All you've ever wanted to know about slumber parties but were afraid to ask."

Twilight: My own personal copy. It's a fantastic reference guide. You should see the table of contents. I've been waiting for a chance to use it, and today's the day. This is gonna be so great!

Rarity: Yes, uh, great.

Later.

Applejack came back inside with clean hooves and gasped.

Applejack: What in tarnation?

She saw Rarity and Twilight applying mud mask while Y/n was leaning against the wall reading over Twilight's book.

Applejack: Now wait just a golddarn minute! You make me wash the mud off my hooves, but it's okay for y'all to have mud all over your faces?

Rarity: Silly. This is called a mud mask. It's too refresh and rejuvenate your complexion.

Twilight: We're giving each other makeovers! (giggle) We have to do it. It says so in the book.

Y/n: Indeed. Some of these things actually look pretty interesting. There's snacks, stories. Though, there's something in here I've never heard of. It's called, "Seven Minutes in Heaven."

Twilight: Oh, that's the one I'm looking forward to the most! But we'll save it for later.

Applejack: Uh, hey (chuckle) Would you look at the time? I got to skedaddle on home quick. I'm powerful late for, uh- For something. Uh, good night.

Applejack attempted to leave, but the lightning outside scared her back inside.

Applejack: Or maybe I'll sit here for a spell.

Twilight clapped her hooves together happily.

Twilight: Hooray, slumber party!

Rarity slapped mud on to Applejack, rubbed it in, and placed cucumber slices over her eyes.

Applejack: What in the world is this for?

Rarity: (sigh) To reduce the puffiness around one's eyes, of course.

Applejack: Puffiness, shmuffiness!

Applejack ate the cucumbers off her eyes.

Applejack: That's good eatin'.

Rarity gave Applejack a look of slight disdain.

Twilight: (giggle) Isn't this exciting? We'll do everything by the book, and that will make my slumber party officially fun.

Rarity: Did you hear that, Applejack? You certainly would not want to do anything that would ruin Twilight's very first slumber party, would you?

Applejack: Of course not. And you wouldn't, either, I reckon.

Rarity: So, do we have an agreement?

Applejack: You betcha.

Applejack spat in her hoof and offered a hoofshake which disgusted Rarity.

Rarity: Oh, gross! You know, there's messy, and there's just plain rude.

Applejack got in her face.

Applejack: You know, there's fussy, and there's just plain gettin'-on-my-nerves.

Rarity: Fortunately, I can get along with anypony, no matter how difficult she may be.

Applejack: Oh, yeah? Well, I'm the get-alongingest pony you're ever gonna meet.

Rarity: That's not even a word.

Twilight: This is gonna be the bestest slumber party ever! Yay!

Rarity/Applejack: Yay.

Y/n: Well, I might be stuck, but at least it's with someone like Sparkle.

Applejack: What's that mean?

Y/n: See, I made a list for all of you that determines how annoying I find you all. Twilight Sparkle here ranks second least annoying.

Applejack: Out of curiosity, where do I rank?

Y/n: You are the third least annoying.

Applejack: Hmm. I guess that's fair.

Rarity: No need to tell me that I'm the least annoying, your highness.

Y/n: Hate to burst your bubble as they say, Rarity. But you're actually the second most annoying.

Rarity What?!

Applejack bursted out in laughter.

Later.

The three mares had hair curlers in their manes.

Rarity: So... How are you getting along over there, Applejack?

Applejack: (annoyed) Just fine, Rarity.

Twilight: This is so awesome!

Twilight giggled as she made a check mark in the book.

Twilight: Make over- check.

Twilight used her magic to make the curlers disappear.

Y/n: What's next, might I ask?

Twilight: Ooh! It says here we have to tell ghost stories. Who what's to go first?

Applejack: Me! I'd like to tell y'all the terrifying tale of the prissy ghost who drove everypony crazy with their unnecessary neatness. Ooooh! I'm sure y'all are familiar with that one.

Rarity: Never heard of it, I have a much better one. It's the horrifying story of the messy, inconsiderate ghost who irritated everypony within a hundred miles! Ooooh!

Applejack: That's not a real story! You made it up!

Rarity: It is a ghost story. They're all made up.

Y/n: Not all of them.

Applejack/Rarity/Twilight: Huh?

Y/n: Well, they aren't necessarily ghost stories, but some ponies would find them quite terrifying.

Twilight: Could you tell us one of these stories?

Y/n: Hm. I guess. But be warned, I don't fully remember some of these stories, so you'll likely be getting an Abridged version.

Rarity: That's fine, I guess.

Applejack: And here I thought you were going to be all nitpicky about wanting to be a full story.

Y/n: Enough. Do you want a story or not?

Rarity and Applejack looked at Twilight's enthusiastic face.

Rarity/Applejack: We do.

Y/n: Good to hear. Sparkle, turn off the lights.

Twilight turned out the lights and placed a lantern in the middle of all of them.

Y/n: Now, I shall tell you a little tale from my past life. It's the story of how me and a few other ponies came in contact with being known as "The Pony of Shadows." It was a dark and stormy night, not too dissimilar from this one, me and a few colleagues of mine were in some building, when the door suddenly bursted open. From it, a pony that looked like it was made of pure darkness appeared, this was The Pony of Shadows. Now, this is the part that's a blur to me, but what I do remember was when I opened my eyes, my colleagues were gone and I never saw that thing again. I still wonder how I got out unharmed and where that creater is now, but wherever it is I hope it never comes back.

The three mares actually looked pretty shook from that story as they huddled together, but Y/n kept a straight face as he turned on the light.

Y/n: Well, that was slightly entertaining. What's next?

Twilight: Well, how about we make s'mores?

Y/n: Some more what?

Twilight: Uh, that's not what I meant.

A little later.

Applejack and Y/n roasted some marshmallows over Twilight's fire place while Rarity was teaching Twilight how to make s'mores.

Rarity: Then you place one marshmallow on top of the chocolate. And be sure it's centered. That's critical. And then carefully put another perfectly square graham cracker on the top. And... (completed the s'mores) Done. Ta-da.

Twilight: Ooh!

Applejack: Nah, you just eat 'em.

Applejack ate a s'more unmannerly and burbed which annoyed Rarity.

Rarity: (scoff) You could at least say, "excuse me."

Applejack: Oh, I was just about to, but you interrupted me. Pardon.

Y/n took a s'more and ate it.

Applejack: How do you like that there, Sire?

Y/n: Mmm. This is actually quite good. What's this delicacy called again?

Rarity: It is known as a s'more, your highness.

Twilight got out her cheek list.

Twilight: S'mores- check. Now the next item of fun we have to do is truth or dare.

Rarity: I dare Applejack to do something carefully and neatly for a change.

Applejack: Oh, yeah? Well, I dare Rarity to lighten up and stop obsessin' over every last little detail for a change.

Rarity: I think the truth of the matter is that somepony quick stand to pay a little more attention to detail.

Applejack: And I think the truth is somepony ought to quit with her fussin' so the rest of us can get things done.

Twilight: Um, I don't think this is how the game's supposed to work. You have to give an honest answer to any question or do whatever anypony dares you to do.

Applejack: (looks to Rarity) I dare you to step outside and let your precious tidy mane get ruined again.

Rarity gasp.

Twilight: You have to. It's the rule.

Applejack: Ha!

Rarity: Fine!

Rarity reluctantly went outside and got her mane all wet which made Applejack laugh. Rarity, with the less then pleased look began to back Applejack into the wall.

Rarity: Okay, I dare Applejack to play dress-up in a froufrou, glittery, lacy outfit.

Applejack gasped, but reluctantly put on a dress.

Applejack: Happy?

Rarity: Very. (small chuckle)

Twilight: Um, do I ever get a turn?

Applejack: I dare you to enter the next Rodeo when it comes into town.

Rarity: I dare you not to enter the next Rodeo that comes to town.

Applejack: I dare you to not comb your mane 100 times before bed!

Rarity: And I dare you to comb yours just once!

Y/n was beginning to look annoyed.

Y/n: Enough! I have a dare for both of you. I dare you both to quit arguing like brats, and handle your problems with each other like big fillies!

Applejack and Rarity were a bit taken aback by Y/n's sudden outburst and just nodded.

Y/n: Good. Now, Twilight, would you like a turn?

Twilight: Oh, uh. Y/n, Truth or dare?

Y/n: Hm. Dare.

Twilight: Well, I dare you to give me a hug.

Y/n: A hug, really?

Twilight: Uh, you don't have to if you don't-

Y/n: No, it's fine.

Y/n gave Twilight a quick hug which made her blush.

Y/n: Now, truth or dare, Twilight?

Twilight: Uh, Truth.

Y/n: Out of all the Elements of Harmony, who do you like the most?

Applejack and Rarity were intrigued to know this, too.

Twilight: Oh, uh... (blushing) Y-you.

Y/n: Me?

Twilight: (blushing) Y-yeah.

Y/n: Hmm. All right.

Twilight: I think we should check off truth or dare now and move on.

Y/n: Sounds good to me.

Twilight: let's see what our next fun, fun, fun thing is, shall we?

Twilight read through the book.

Twilight: Hmm, what does this mean? "Pillow fight"?

Rarity: Oh, please. I am not all interested in participating in something so crude.

Applejack threw a pillow at Rarity which she obviously didn't like.

Rarity: It... Is... On!

Rarity and Applejack went into an intense back and forth of throwing pillows at each other.

Twilight: Oh, I get it. Pillow... fight. Fun!

Twilight got it by two pillows and got knocked to.

Twilight: Uh, girls. Maybe we should take it down a notch.

Applejack: I will if she will.

Rarity: She started it.

Y/n was again getting annoyed and used his magic to throw Rarity and Applejack's pillows back at them harshly and knocked them both over.

Y/n: I believe I am the winner. What's next?

Twilight checked the book and looked excited.

Twilight: Ooh! This is what I've been looking forward to the most! Seven Minutes in Heaven!

Y/n: And what is that?

Twilight: It's where two ponies are selected to go into a closet or other dark enclosed space and do whatever they like for seven minutes.

Y/n: That could be good for Applejack and Rarity as it would give them a chance to talk about whatever they're fighting about.

Applejack: There's nothing to talk about.

Rarity: Hmph.

Twilight: Well, (blushing) you and me can do it, your highness. If you want, that is.

Y/n: I've got no problem.

They both entered the closet and turned out the lights, with the only way to see being the light from Twilight's horn.

Twilight: So, uh, what do you want to do?

Y/n: I don't know. I'd ask if you'd like to spar or practice magic, but this closet isn't big enough for that.

Twilight: Well, how about we read?

Y/n: Something quiet. I like it. What do you want to read?

Twilight: How about... (looks through books until she finds one) this one? It's about a brave knight slaying a ferocious dragon to save a princess.

Y/n: Sounds promising.

They both sat down and began to read.

Seven minutes later.

They finished the book and Y/n closed it.

Y/n: That was better than I thought. How did-

He turned and saw Twilight was asleep and fell gently on his shoulder.

Y/n: (sigh) Guess it can't be helped.

Y/n gently carried Twilight out.

Applejack: What were you two doing in there?

Y/n: If we wanted you to know, we would've took you with us.

Y/n gently placed Twilight in her bed that was across from another one.

Y/n: I think it's time to turn in. You two share the bed that Sparkle offered me.

Rarity: What about you?

Y/n: I never used it, I'll sleep in the living closet like I've already been doing.

Applejack: Hold on. Twilight offered you a bed and you gave it up so you could sleep in the closet? Why?

Y/n without any expression got in Applejack's face and calmly said...

Y/n: I'm a warrior.

Y/n walked downstairs and shut himself in the closet.

Applejack: Wha- That don't even make a lick of sense!

Rarity: (sigh) Let's just try and get some sleep.

Later.

Rarity and Applejack were facing away from each other on the bed.

Rarity: Keep your muddy hooves on your side of the bed.

Applejack: My hooves ain't muddy.

Rarity: They were. There might still be a little on them.

Applejack: There ain't. See?

Applejack shoved her hoof in Rarity's face.

Rarity: Ew!

Rarity pulled all of the blanket towards her which obviously annoyed Applejack.

Applejack: Now who's bein' inconsiderate?

Applejack took the covers which made Rarity get off.

Rarity: I have to make the bed again so the blanket will be right. Get up.

Rarity pushed Applejack off the bed and used her magic to fix it up. Applejack tried to get under the covers, but Rarity stopped her.

Rarity: Unh-Unh-Unh. You'll ruin it. You have to do it like this.

Rarity slowly slipped into the blanket without even slightly moving it.

Applejack: Yeah. That's not gonna happen. Geronimo!

Applejack jumped onto the bed and made Rarity fall off.

Rarity: You did that on purpose.

Applejack: Um, yeah.

Rarity: Get up so I can fix it again.

Applejack: Can't hear you. I'm asleep.

Applejack faked snoring which annoyed Rarity so she tore the blanket off, but Applejack wouldn't let up.

Applejack: I ain't budgin'.

Rarity: You will if you want any blanket!

Applejack tried to take the blanket away from Rarity which lead to them going back and forth until Twilight woke up.

Twilight: Enough!

Rarity and Applejack stopped struggling and looked at Twilight who brought out her guide.

Twilight: It says right here that the number one thing you're supposed to do at a slumber party is have fun. And thanks to you two, I can't check that off.

Applejack: I've been trying my darndest to get along.

Rarity: No, it is I who have been trying my best.

Applejack: No, it was me.

Rarity: No, it was I.

They got in each others faces again.

Applejack: Me!

Rarity: I!

Twilight: I hope you're happy, both of you. You've ruined my very first slumber party- the makeover, the s'mores, truth or dare, the pillow fight! I mean, is there anything else I could possibly go wrong?!

They heard lightning strike outside.

Twilight: Sorry I asked.

They looked outside to see the lightning hit tree that looked like one of its branches was going to tip over.

Applejack: You see? That's why we needed to take down all those loose branches in town, not spiffy 'em up.

Rarity had a sad look.

Rarity: But I-

Applejack: Out of my way, missy!! Time's a-wastin'.

Applejack open the window and got out her lasso.

Rarity: Wait! Stop! Don't!

Applejack: No waitin'! No stoppin'!! Doin'!

Applejack used her lasso to stop the branch from falling.

Applejack: And that, my friends, is what we call "Gettin' her done."
Applejack pulled on the branch which caused to come into the library, leaving the window open and letting wind and rain in. That's when Y/n came out.

Y/n: What's going on here?

He noticed the branch.

Y/n: Am I dreaming?

Applejack: Sadly, no.

Rarity: I tried to tell her it would come crashing down in here!

Applejack: Well, you should have tried harder!

Y/n: Both of you straighten up.

Applejack: (sigh) I'm mighty sorry, Twilight.

Twilight: It's- Well, it's not okay. There's a giant tree branch in the middle of my bedroom! And the book doesn't say anything about having a giant tree branch at your slumber party- Or at least I haven't found that entry yet.

While all this chaos was going down, Rarity was picking up the books that fell over.

Y/n: Mother of- Rarity, only you would worry about neatness at a time like this.

Applejack: We've got to do something!

Y/n: I could just destroy the branch.

Rarity: No way! What if you accidentally hit one of us?

Y/n: Then what's your big idea? All you're doing is cleaning up books which is far from the main issue.

Applejack: Yeah! Quit sweating the small stuff.

Y/n: Applejack, you are not blameless either. In situations like this, it's best to act as well as pay attention to detail.

Applejack: ...Rarity- Look... I'm sorry, all right?

Rarity: What was that?

Applejack: I said, "I'm sorry"! I should have listened to you when you noticed where this here branch would end up. You're annoyin' attention to detail would have saved us from this whole mess. But right now, you need to stop bein' so dang fussy, pickin' up all those little things, and help me move the one big thing in here that actually matters!

Rarity thought for a moment.

Applejack: Please!

Rarity: Uh, uh, but I'll get all icky.

Y/n: Rarity, they're bigger things in life than getting a little messy. Now, do you want Twilight's room to be ruined?

Rarity thought for a moment before smiling.

Rarity: Let's do it.

Rarity used her magic to make a bunch of little shrubs in the shape of ponies. The last thing of the branch was a stump that Applejack was going to buck away, but Y/n stopped her.

Y/n: Please, allow me.

Y/n used his magic to gently drop the log. At the end of it, Rarity had dirt, leaves, and sticks all over her.

Rarity: I look awful.

Applejack placed cucumbers over Rarity's eyes.

Applejack: Better?

Rarity: (small chuckle) Thanks.

They both gave each other a hug.

Y/n: Seems like everything worked out in the end.

Twilight noticed the shrubs.

Twilight: Ooh, pretty. Where did these come from? They're not in the book, either.

Later.

The mares were laughing and sitting in the floor with Y/n.

Applejack: Is it bigger than a barn?

Twilight: (chuckle) Nope.

Rarity: Is it smaller than a saddle?

Twilight: (chuckle) No. Only three of your 20 Questions left.

Y/n: Is it useful for something.

Twilight: Definitely.

Applejack: Is it... a six-legged Pony with a purple, polka-dotted mane and shootin' stars comin' out of its eyes...

Rarity: Who flies throughout the air all over the world to hide magic, sparkly eggs?

Y/n: Why the Tartarus would it be that?

Twilight: That's it!

Applejack/Rarity: It is?

Y/n: Really?

Twilight: No. (chuckles and points to her telescope) It's that. But it was just so nice to see you two finally getting along, I wanted you to be able to win together.

They both laughed at that.

Twilight: See? We could have been having fun like this all along.

Applejack: If only somepony hadn't been so persnickety.

Rarity: Well, maybe she wouldn't have been if somepony else hadn't been so sloppy.

They both glared at each other then went back to kind expressions.

Applejack: Sorry for bein' such a pain in the patootie.

Rarity: Oh, no. I'm sure I was much worse.

Applejack: That's kind of you to say, but I'm the one who's sorry.

Rarity: Oh, I'm much more than you are.

Y/n: How about we just say you're both sorry and move on.

Applejack: Well, okay.

Twilight: I declare my first slumber party a success.

Twilight got out the list.

Twilight: Have fun- check.

Later.

Applejack was blinded by cucumber slices while Rarity was guiding her.

Rarity: Now take two steps to your left. Uh, no, my left.

Applejack: Well, which is it?

Applejack walked into a book pile and knocked it over.

Applejack: That mess was your fault, not mine.

They both laughed.

Rarity: Sorry.

Twilight began writing a letter to Celestia.

Twilight: (Thinking: "Dear Princess Celestia, It's hard to believe that two ponies who seem to have so little in common could ever get along. But I found out that if you embrace each other's differences, you just might be surprised to discover a way to be friends after all.")

Y/n: Well, I think it's time for us to turn in.

Twilight: I'm guessing you're gonna go back to the closet.

Y/n: Actually, I think it'd be best if I was in a room with you guys just to make sure nothing like that ever happens again.

Twilight: Oh, well, you could, uh, (blushing) sleep in my bed with me.

Y/n: Are you sure? I wouldn't want to take up any room.

Twilight: Positive.

Later.

Everyone was asleep when Twilight woke up filling a vibration next to her.

Twilight: Huh? What the-

She turned to see Y/n was shaking next to her.

Twilight: Prince Y/n?

Y/n: (sleep talking) Luna...

Y/n began to let out quiet sobs which made Twilight look at him sympathetically.

Twilight: (Whispering: My poor Prince.)

Twilight cuddled into Y/n which made him stop shaking.

To be continued.
