Well, this isn't where I found out the name of AW/Fleet's phone, but it fits the description, Transcript. (Admins please link.) http://www.cricketmagkids.com/chatterbox/chirpatcricket/node/423000 But I wonder what it has to do with "What's wrong with Nyx? You ponder in mind name your phone ace and answer you'll find..."

HOLY-

I just saw this today and yikes... 

Still a good story though.  Maybe I need to come up with a ski lodge later this year... hmmm

Transript!!!!!! You and Estella are driving me bonkers! But this is what I found from the combination of your two clues, on that thread:

An excerpt from Estella's folder titled "The Ski Lodge's Happenings."

 Atlantis, Apollo, and I found Spring's corpse near the mirror maze. Wren soon came over with a crowd of drenched guests: Ameri, Maddox, Nyx, Alice, Naomi, and Dusk. Ameri tackled Apollo, drenching him too, but the tacklee screamed at him and pointed to Spring's body. 

 "All White Oak guests report to the entrance, our trip is ending early. All White Oak Guests to the entrance, our trip is ending early." Wren stated over the portable intercom. She hesitantly added after receiving my signal, "Spring has been murdered."

 Per my expectations, the ride home was silent. When offered dinner, most guests politely refused and excused themselves to their rooms. Those who did eat either sat by themselves, with their 'Family' or awkwardly conversed with the scientists. About half left early to eat in their rooms, and the amount of waste tonight was insurmountably high. One fight did erupt between Ameri's and Alex's group. I kept a close watch on them, however, and was able to defuse the conflict in an efficient manner. 

 Hall Checks: numerous guards broke the rules by comforting Summer amid her grievous sob session. Upon rethinking the event, I may not reprimand them; this could provide some invaluable data about human emotional reactions. For now, I must prepare. Tomorrow's experiment will cost about [REDACTED], and I can only hope [REDACTED] will keep her promise and pay the tab. This experiment is imperative: if it exceeds my expectations, we could end the test now.

 I must admit that I have become a bit stressed through [REDACTED]. I know, I know, it's unreasonable: frankly, I don't understand it either. Everything is going according to plan, and the only major issue is cost. Maybe it's just my guests' uniqueness.

 I do know that in the wake of tragedy, conflict is to be expected...but a food fight? On the first death? It's foolish, I know. Still, I can't help worrying. 

***************

 "Y'know," Ameri grinned as he skipped into the dining room, "Maybe Ms. Opafru's not that bad!"

 "You're only saying that because of the banquet," Alister rolled his eyes. In the light of recent events, Estella was holding a banquet to lift spirits. It would include all of the guest's favorite foods, as well as worldwide delicacies.

 "Can you blame me?" Ameri snatched a loaf of bread off the counter and cracked it open, "Free food is free food, man! And it's even better when it's a deligh-delik-delili-"

 "Delicacy." Alister plopped onto a chair.

 "Yeah!" Ameri hopped into the one next to him, "Whatever the heck!"

 "Ameri!" Kanib tapped the boy's shoulder, "You're it! Alex is playing too!"

 "Alex, huh?" Ameri shoved his chair in, "Wonder what she'll have to say when I CORNER her!" 

 "Good grief," Alister picked up his brother's loaf and split it in half. He noticed a huge bubble in the left half but shrugged it off.

 "May I pour your tea, madam?" La'Crosse asked haughtily, spilling a bit of tea on her plate.

 "But of course, monsieur, but of course," Summer snickered. La'Crosse poured the tea but nearly dropped the pot when Ameri jammed into her. Summer finished off her cup and filled La'Crosse's, who was scolding the male AE. 

 "Yeesh, what a headache..." The motherly CBer plopped into her chair, holding her head.

 "Yeah, but at least you..." Summer's face dropped, "...have one..."

 La'Crosse slapped her buddy on the back.

 "Hey, long-face," She smiled, raising her cup, "Let's just make the most of right now, okay? I have no idea what you're going through right now, but I do know that mulling over it won't make her come back." She leaned back in her chair, "Like the great La'Crosse once said, 'Live your best life, because you never know when it'll end!"

 "Cheers!" The girls clinked glasses. Summer finished hers before realizing her friend wasn't doing the same.

 "La'Crosse," She turned to the right, "You're supposed to drink after-"

 She stopped. Her head pounded. She coughed, unable to breathe. Her pupils dilated, heart raced, pulsed quicked, arms shook, her whole body began to convulse and panic before-

 THUMP.

 "SUMMER!"

 The shriek shook Wren out of her trance. She grabbed Estella's arm and rushed to the banquet room. The elder questioned her actions and struggled to keep up until-

 Oh no.

 Estella quaked, her veins burning and pulsing with red-hot fury. She had everything planned perfectly, she finally had a way to get all of these fund draining nuisances away from her so she could sort the notes, but then this has to happen, of course, she expected a rest, how silly of her!

 "Estella, are you okay?"

 "NO, I'm not okay!" She screeched, "Do I LOOK okay?! This is supposed to be calm, organized, and orderly, but I have CHILDREN starting FOOD FIGHTS and throwing SLING BAGS out of WINDOWS, which cost us God knows how much in property damage combined! Not to mention, all these guests seem to do is cry in their bedrooms instead of doing anything USEFUL! Gosh, this whole experiment is nothing more than a migraine-"

 "EXPERIMENT?" Dusk screeched. Estella stopped. The room fell into silence.

Step.

Step.

Step.

 "Ladies and gentlemen," Alister sneered, "You heard our wonderful host. This is all just an experiment! We're nothing more than test tubes, pawns adjusted to fit requirements and collect data." He paused. His fellow guests shrunk when he paced near them.

 "And that's just for starters!" he laughed, "That'd be a better fate than this hellhole, 'cause at least experiments have order and structure! At least the conductor knows the music she's conducting! But she has no control. That's right. Miss Estella Opafru is just like the rest of us." He stopped right in front of Estella, leaning in to deliver the final blow.

 "Powerless."

 "Alister, that's enough." Wren grabbed Estella's arm.

 "What's wrong, m'lady?"

 "Alister, stop."

 "White flag got your tongue?"

 Estella lunged for Alister, grappling onto his shoulders. Someone dove into Estella's side.The staff rushed the guests out, but they saw the flashes of light and blackened strings. Amidst all the chaos, the one person who should have felt in control was lost as well.

 They didn't plan to kill anyone today. And they sure didn't kill Summer. There was only one answer to the constant barrage of questions plaguing their mind:

 Someone was playing dress-up with bloody clothes.

Ok so I was just looking though the story and I think I found something.  I think Nyx is the murderer.

Ok ok let me explain.  So in the puzzle it was said that in Ace's phone you'd find pink. (I think?)  When Fleet (or AW. however her name is in here.)  fainted or passed out (I just re-read the first part of the story when i realized this. So i'm mixing stuff up sorry XD)  They knew she was alive when she muttered "Pink... pink... pink" afterwards she went to Nyx and called her a traitor.  

Now when Estella gave everyone keycards, Nyx's was the pink dolphin. 

Estella, you don't have to say if i'm right.  Since it would ruin the story.
