"Goodnight," Pinkie said. She then went upstairs. Twilight felt devastated. She felt that she had lost Pinkie. After everything that had gone down in the past 48 hours, she had come to expect the worst of the worst. Now, Pinkie Pie's happiness was gone. She didn't know how long this would last, but she was deeply hurt by it.
Like a spark hitting a puddle of gasoline, Pinkie's random personality change ignited Twilight's stress, causing her to overreact. She bolted from Sugarcube Corner and flew to the clouds to get away. Running away from her friends in a strange time without even taking any aspect of the situation into consideration really was overreacting, but she didn't care. All the stress she had bottled up in the last 48 hours had finally exploded when Pinkie lost her cutie mark.
"What the?" She thought as she flew. She saw smoke rising from a cloud. Since fire rain only exists in books, well, for now at least since anything could happen, she went to investigate it. It was a thin beam of smoke, so it must of been a thin beam of fire. She began to notice that it came out in random puffs, confusing her even more. She was confused the most when she got to the cloud to see Rainbow Dash sucking and blowing on some burning leaf, which caused the smoke.
"Oh hey Twilight," Dash said.
"Get that thing out of your mouth!" Twilight said, "You're gonna burn yourself!"
"No I ain't. I've been doing this off and on all day."
"What are you doing anyway?"
"I got hit by a beam of magic, and suddenly I have the power to go 50% faster than I usually could. Obviously, I use that power frequently. Strangely, every time I do that, I got an unbeatable urge to go into the part of the Everfree that's still intact and get some weird leaf, roll it up in paper, burn one end, and suck the other. I don't know how it happened. But I think I'm like a contractor or something."
"How do you know what that is?"
"I read more than just Daring Do. It was mentioned frequently in some non-fiction book I read about Luna's banishment and the fake night sky."
"Wow. You knew more about it than I did."
"I guess that's pretty neat. So, how'd your mission go, 'Mare Do Well'?"
"What the!? How did you-"
"Saw the whole thing. I recognized your posture, mannerisms, and the fact that you stole Shining Armor. I was kind of surprised to see you use contractor powers, which made me doubt my original theory that it was you, but seeing the scars on you right now, and knowing that you'd never intentionally harm yourself like that and that you're too smart to cut yourself like that three different times in the same day, I have confirmed my theory. You've got a scar for each time you've used your power. Tough price. Did you get a cool power though?"
"I can manipulate electricity."
"Neat."
"No, not really. I have to deal with this curse for potentially the rest of my life."
"But you can manipulate electricity. There are so many things you can do with that."
"Like what, kill?"
"Well, yeah."
"Have you killed anypony yet?"
"What!? No! Of course not!"
"Man. If I were you I would've stormed into Canterlot and killed every single one of those jerks from the military. I don't believe any of their nonsense."
"So you know the truth."
"It's obvious. He called himself a Führer. It's obvious that he's evil. All the mindless sheep of Ponyville only cared about Celestia and the fact that the Sun will never rise again, neglecting the fact that the military clearly overthrew her somehow."
"Yeah that's entirely true. Her real letter of resignation said that she put Cadence in charge, but as expected, the military perverted it."
"Those creeps."
"Rainbow, you seem really angry and jerk-like."
"Why do you say that?"
"You're REALLY hating on the military-"
"Don't you hate them too?"
"Yes, but let me finish."
"Sorry."
"Anyway, you're really hating on the military, and you asked if I killed anypony. You know I wouldn't do that."
"Hmm. I dunno why I'm like this. I didn't notice."
Twilight sat there thinking.
"Oh no" Twilight said.
"What?"
"Celestia told me in a letter that contractors lose their sense of morals. Sometimes gradually, sometimes quickly. She said you can still have a viewpoint on things, you can still take sides and what not. But in action, you're ruthless."
"Looks like I lost mine quickly."
"It really does look that way. Say, before you get any worse, join me."
"In what?"
"You did see me attack the military meeting, right?"
"Yeah, so?"
"I'm fighting for justice. Celestia told me to attack them. She's still going to communicate with me secretly. Join us. We have to fight."
"Eh. I guess I have no reason to not join ya."
"And you're not gonna leave us, right?"
"Come on. I'm the Element of Loyalty. Of course I'll stay with you."
"Thank you."
"Any time."
"Now I gotta tell you about Pinkie Pie."
"Huh?"
"We were all down at Sugarcube Corner and-"
"You didn't invite me?"
"No. Nopony got an invite. We were just all depressed and wanted to drown our sorrows in frosting and laughter. We just all happened to go there at the same time."
"Ah. Ok."
"So, anyway, we were there, then Pinkie went to the bathroom-"
"Everypony poops."
"Rainbow! This is serious!"
"Sorry. Couldn't help it."
"Anyway, when she came out, she lost all of her spirit and happiness. Her hair was straight, her face was emotionless, and she told a terrible joke in an extremely dull voice. Then I noticed that her cutie mark was gone."
"What!? Gone!?"
"Yeah. She said goodnight to us and went upstairs slowly."
"Weird."
"I then overreacted and assumed that she'd be like this forever, which lead me to run out of there and fly into the clouds to get away from everything, then I saw a smoking cloud, which I wanted to investigate-"
"So it lead you to this cloud here, to see my sucking and blowing some weird leaf, and now you're explaining what we're doing right now."
"Yup."
"Well I better get home now."
"Ok. See you around."
"Peace."
Rainbow flew away. Twilight flew back to Sugarcube Corner and apologized for running away. She then flew back home and jotted down a quick letter to Celestia,
"Dear Celestia,
Pinkie Pie has turned dull.
She went into the bathroom as herself, then came out with straight hair, a dull voice, and no cutie mark. She told an awful joke, then left.
What happened?
-Twilight Sparkle"
She went to sleep.
