The morning sun shown brightly in the sky as the girls headed towards Canterlot High, still somewhat agitated the had to start their day on "less then half a tank" as Rainbow Dash had put it. Rarity sipping her coffee doing her best to stay awake and Applejack still looking rather grumpy, Fluttershy yawning as she stroked Angel Bunnie's forhead and Pinkie well, Pinkie was more or less her usual energetic self. Meanwhile Sunset and Twilight walked behind the group to get any additional information they could out of Aria and Sonata as the latter of the two pushed Adagio's wheelchair, the Dazzling's leader still out for the count.

"And she wasn't showing any prior signs of fatigue or illness?" Twilight asked

"Nope, she was just her usual self until last night" Sonata replied.

"really, not a single warning sign? She wasn't extra irritable or irrational or anything? " Sunset asked in surprise.

"No more then usual" Aria mischievously chuckled

"Hmm, interesting, an illness that strikes suddenly and leaves its victim unconscious. I can't say i've heard of many like that, let alone any cases of such here in Canterlot City, far off places like Saddle Arabia or Somnabula sure, but such a mysterious and fast acting sickness here, I never thought....." Twilight trailed off deep into her own thoughts.

Sonata just looked at the glasses wearing girl and made a nervous gulp.

"Hey, don't worry" Sunset reassured her. "We'll figure out what it is. I promise" She smiled at Sonata. "But first we need to get to school and explain the situation to Celestia and Luna." she stated.

"Do, do we have to?" Aria nervously asked the bacon haired teen.

"Well, yea, I kind of promised them i'd give them the heads up anytime there were some magical mishaps going on, after the Battle of The Bands and The Friendship games those two have gotten a bit weary of all this" Sunset chuckled.

"Well, ahh, OK" Aria nervously replied. "Then I-I guess you'll wanna give em this back." She gulped as she pulled Sunset's file out of her hoodie.

"What the, where, how?" Sunset asked surprised.

"Yea, I-I kind of broke into your school last night to steal your file so we could figure out where you lived, and I may have almost gotten caught by that Vice Principle Luna chick." Aria nervously half smiled.

"You did what!?" Sunset exclaimed in surprise.

"Well, it seemed like a good idea at the time, I mean, we had to find some way of tracking you down" Aria huffed

"You could have just used a phone book or googled it" Twilight responded

"Whatever" Aria angrily blushed.

Sunset just let out a small laugh and sighed. "OK, don't worry, I promise i'll get everything settled, you and Sonata just worry about taking care of Adagio while we figure this out."

"Sound good to me" Sonata smiled

"Whatever" Aria huffed.

The front of Canterlot High looked impressive as ever, the giant horse statue which contained the magical portal back to Equestria was still in pristine condition and the grass and plants on the ground still well kept. The building itself having gone through various repairs over the past year due to all the magical shenanigans Sunset and her friends had been inadvertently responsible for still stood proud and tall, the sun reflecting off the crystal clean windows and the light brown brick accenting the colorful window and door trim quite well. In the front of the school students walked and chatted as they got ready for their day. Flash Sentry could be seen strumming his guitar and Lyra and Bon-Bon were sneaking to the side of the school to get in some "playtime" before the first bell rang. Derpy was snacking on muffins as Octavia and Vinyl argued on the step behind her and Sandlewood and Treehugger were just sitting on the grass enjoying the nice sunny day.

"Well it looks at least everyone else is having a good day so far." Rarity chuckled as she finished up her coffee.

"Of course, any day i'm here is an awesome one!" Rainbow Dash egotistically chimed in.

"OK girls, enough joking around, we need to stay on task." Sunset reminded them. "Twilight and I will go talk to Principle Celestia and Luna and explain the situation. Aria you and Sonata take Adagio to the nurses office and wait for us there. The rest of you girls wait for us in the library, we have a long day of research ahead of us." Sunset stated.

"OK" The rest of the group moaned, the thought of having to spend the entire day pent up in the library not being the most appealing one.

"Don't worry girls" Sunset reassured them "We got this!"

"So, let me get this straight" Principle Celesta sighed in a rather serious and tired tone as she starred down at Sunset and Twilight. "The Dazzlings, the same group of girls that turned out to be magic absorbing sirens from your homeland Sunset are back in my school in my nurses office?" Celestia asked rather concerned.

"Um, yes." Sunset nervously replied

"And these same girls were the ones that broke into this school last night" Luna added in rather angrily.

"Um, yes" Sunset meeped. The two sisters looking quite angry at the young girl by this point.

"Um, Principle Celestia, Vice Principle Luna, if I may" Twilight interjected.

"Yes Twilight?" Celestia responded looking straight at the adorkable girl.

"Well, I know the situation doesn't sound ideal, but from what I can tell the Dazzlings really are in need of our help. Whatever powers they had, Sunset and the Twilight from the other world most deffinintly nullified it, or at least their ability to access it." Twilight muttered. "I don't think they will pose any threat to the school or its students" she added.

"That may be, but they're still criminals" Luna stated as she slammed Sunset's file on the desk.

Sunset just gulped and let out a deep sigh. "I know that breaking into the school was wrong, but, they just wanted to find a way to help their sister, and I don't really think they can afford cellphones. They had to find us somehow." Sunset explained.

"Even so, they must still be punished" Luna growled.

"Now now sister, its not like you were a saint yourself at their age" Celestia responded "Or did you forget that whole uber goth Nightmare Moon phase you had back in highschool" Celestia chuckled.

Luna just blushed, her face deep purple "You, you promised we would never speak of that again" She stuttered.

"Well then, it's settled" Celestia replied. "Sunset, we will leave this situation up to you and Twilight, and if things do turn out for the better we allow The Dazzlings to return to CHS proper, but you and the rest of The Rainbooms will be in charge of keeping them in line. We've all worked hard to make this school a better place and I would hate to see all of you and the other students hard work ruined." Celestia replied with concern.

"Thank you Principle Celestia, and don't worry, I promise we've got everything under control!" Sunset reassured her.

" I freaking hate this!" Aria angrily screeched as she punched a hole in the wall of the Nurse's office. The resident school Nurse Redheart having left the room long ago after Aria had threatened to rip her limb from limb if she even tried to touch their sister.

"She was just trying to help Aria!" Sonata huffed.

"And what kind of help could some stupid human nurse do anyway huh!?" Aria argued.

"I dunno, but you could have at least let her take Adagio's temperature, it wouldn't have hurt." Sonata angrily replied.

"You don't know that" Aria growled "It's bad enough we have to trust those Rainbow Retards with our sister's life, no way in Hades am I gonna trust some stupid human!" Aria scowled.

"Wow, you two like never stop arguing, do you." They heard a voice chime in. The two siren sisters turning around to see Rainbow Dash and Pinkie Pie.

"What are you doing here?" Aria asked, her voice still quite angry.

"Sunset told us to come keep an eye on you two, make sure you don't tear up the school or anything" Rainbow laughed pointing at the hole in the wall. "But looks like we got here a little late" She chuckled. Aria just crossing her arms and huffing.

"That and we both pretty much suck at studying so we wouldn't be much help to the rest of the girls in the library" Pinkie added in with a smile.

"Wow, so even your friends know you're morons" Aria laughed.

"Ari, be nice they're here to help us." Sonata whinned.

"Whatever, just keep your hands off Adagio and don't do anything to piss me off Rainbow Crash" Aria mockingly replied, Rainbow Dash just rolled her eyes and nodded "whatever" she mockingly replied back.

"pssst, I think this is gonna be a long day" Pinkie chuckled into Sonata's ear. Sonata nodding in agreement, for better or worse, she was probably right.

In the library the rainbooms looked through book after book, medical journal after medical journal, but it seemed their efforts so far were fruitless.

"Ugg, I don't get it, the answer has to be here somewhere doesn't it!? Books always have the answer to everything!" Twilight angrily huffed as she readjusted her glasses and stared even more intensely at her copy of "Mage Medowbrooks Guide to Hollistic 19th Century Medicine

"I'm sorry darling, but I guess this is the one time books just aren't enough." Rarity sighed as she put down the rather large medical journal she had been forced to search through.

"Ah ain't found nothin either" Applejack huffed as she slammed her book down on the table.

"um Angel says he hasn't seen anything, and I haven't either" Fluttershy apologetically chimed in.

"Hmm" Sunset sighed as she put down her own copy of Rare Nautical Diseases

"What is it Sunset?" Twilight asked both curious and frustrated.

"What if" Sunset paused. "What if this isn't a medical problem, but a magical one?" Sunset replied.

"How so darling?" Rarity asked.

"Well, I keep thinking back to Sonata's story, about how their caretaker Coral got sicker and sicker the longer she stayed in the Eastern Sea" Sunset told the group.

"So, that happened over a thousand years ago and in another dimension, what's that gotta do with the here and now?" AJ asked as she crossed her shoulders.

"Well if Coral got sick because she was out of her element too long, maybe its the same thing for The Dazzlings" Sunset replied.

"Come again?" Rarity asked rather confused.

"They may look like ordinary teenage girls, but like me they're really magical creatures." Sunset exclaimed. "I mean think about it, how often have you ever seen me sick?" Sunset asked the group. The other Rainbooms looking at one another in contimplation.

"Huh, now that I think about it, yea never have missed a day a school, heck and outsida Allergy season yea hardly ever make so much as a cough er sneeze" AJ replied.

"Exactly. My magic protects me from any ailments in this world that would be foreign to my physiology, my body was made to handle Equestrian contaminations, not ones from this world." Sunset replied.

"But then why aren't The Dazzlings magic doing the same for them?" Twilight wondered.

"I, I think it's our faults" Sunset sighed. "Well us and the other Twilight's" She quickly amended.

"And how do yea figure that?" AJ responded with an angry huff, not being the type that cared to be blamed for hurting another.

"When we defeated The Dazzlings at the Battle of The Bands our magic completely destroyed their original siren forms and their magical gemstones. Without those they don't have any conduits internal or external to help them contain magic." Sunset remorsefully replied.

"And if they aren't able to keep any magic inside of them they don't have any protection from the natural laws of our world, which means they are susceptible to disease, and being from another dimension entirely even the simplest germ or bacteria could potentially be....a death sentence." Twilight nervously gulped.

"So it's kinda like those aliens in War of The Worlds" AJ chimed in, the group staring at her in surprise. "What, Ah read fer fun from time ta time too." She blushed.

Sunset just cleared her throat and nodded. "More or less." she replied. "But we can't let them suffer the same fate as creatures from some old story" she added.

"Yes, but what can we do about it, it's not like we can just give them our magic darling." Rarity exclaimed.

"True, we can't do that, but....I think I have an idea." Sunset smiled.

"You want to do what!?" Aria shrieked.

"I need to take some blood and hair samples from Adagio and the rest of you so we can help find a cure and keep you and your sister from getting sick too." Sunset explained

"No way bacon butt!" Aria growled "You aren't putting a needle anywhere near Adagio or me, or airhead over there." Aria scowled pointing over at Sonata.

"Not even if it's the only way to save Adagio's life" Sunset calmly asked.

Aria just stood there in silence for a moment as she thought things over. "OK, but, just be quick about it. I don't like needles." She nervously huffed. "Or people pulling on my hair."

Sunset just calmly smiled. "Don't worry, this won't hurt much, I promise." She exclaimed as she and Twilight began taking their samples.

Later the group gathered at the magical portal at the front of the school.

"Huh, so that's the way back to Equestria" Aria asked, a devious grin on her face.

"Yes, but you probably wouldn't want to go through it." Sunset replied.

"And why not?" Aria growled.

"Well given your siren bodies were destroyed if you did follow me through you'd probably just turn into regular ponies, or maybe seaponies, but my bet is on the former" Sunset chuckled in reply.

"Ugg, being turned into a pony, now that's a fate worth then death" Aria shuddered.

"I dunno, I think we'd be cute ponies" Sonata chuckled. Aria just giving her a death-stare in reply.

"So, how do we know this will even work or you'll be able to find a cure in time?" Aria pessimistically asked.

"Well time flows a lot slower in this world then it does in Equestria" Sunset explained "So I can stay there for days working with Twilight to find a cure and it would only be hours here. Trust me, we'll have more then enough time." Sunset reassured them.

Sunset then looked back at her friends before going into the magical portal. "Fluttershy, you Rarity and AJ stay here by the portal. Dash, Pinkie, you follow Aria and Sonata back to the nurses office. And Twy..." Sunset paused as she put her shoulder on her friend. " I am 99% sure this will work, but just in case I would like to have all my bases covered, if you don't mind going back to the library, maybe see if we missed anything." She asked the glasses wearing girl.

Twilight just nodded "I'm on it. Best of luck Sunny, and tell the other me she better not mess this up, cause I know I won't" She replied as she hugged her friend. Sunset returning the embrace before letting go and turning around to enter the magical portal back to her homeland of Equestria.

"Oh, I hope everything works out ok" Fluttershy nervously gulped.

"Don't worry, if anyone can help Sunset find a cure i'm sure Princess Twilight and Starlight are just the people, er ponies to do so." Rarity smiled back at the concerned Fluttershy.

"Humph, They better be." Aria growled as she and Sonata headed back to the nurse's office. Rainbow and Pinkie following close behind.

Author's Notes:

Welp, finally got another chapter out, yay!

Man Aria is one grumpy gal! Given the circumstances though I guess its understandable.

Oh well i'm sure Sunset will be able to find a cure in no time with Princess Twilight & Starlight's help. Though I guess they still have to worry about keeping Aria's Temper under control so she doesn't destroy the entire school before Sunset gets back.

Next time, magical science stuff with a bunch of nerdy pones concocting a brand new kind of potion and Aria argues with pretty much everybody, because of course she does!

Thanks for reading and hope you'll stick around for the next chapeter!
