Jeff in Equestria

Needless to say, Princess Celestia was not amused. She was currently looking at her younger sister. "Luna would you mind telling me exactly what happened again?"

"It's quite simple. I visited Jeff while he was unconscious and recruited him to help us with our problem." Luna sipped her tea.

"THAT'S THE PROBLEM!" Celestia yelled. "Jeff is a homicidal manic, how can we be so sure to trust him?!"

"Because we have the same goal in mind." Luna said. "Even monsters have enemies, and right now we have the same enemies."

"I'm not completely sure I trust your judgement on this Luna, I don't want to lose you again." Celestia said.

"I understand, but this time I will bring any concerns to you. You handle the politics and I'll work from the shadows." Luna said.  "It will be just like olden times sister."

"Alright Luna, but still that doesn't explain the new disease that has been infecting the ponies."

"From what I gathered from Discord, he said that it's Zalgo trying to build his army." Luna said. "The source hasn't been discovered yet, but we need to check all bases."

"That should be of no surprise." Celestia sighed. "We need to meet up with Jeff and his friends."

"I couldn't agree more." Luna nodded and the two took off to their old home.

Jeff and Slender were busy planning their next move. Ben had grabbed the supplies he needed to set up a functioning command center and Masky had helped him. But Eyeless Jack was peeved. "Am I the one that's going to address the elephant in the room?"

"What are you talking about Jack?" Smile Dog asked.

"It's about Jeff." Jack said. "Ever since he brought us to this rainbow shit factory he's been acting unlike himself."

"You really want me to show you that I'm still the same olD kiLlEr I aM nOW?" Jeff's pupils began to shrink. "I mAy bE diFfeRenT BuT I'M stILL mE!"

"Jeff, calm down. Now is not the time or place, we have company." Slender stated while he pointed to the two alicorns in the room.

Jeff looked around, "Hello again Luna. You must be her sister, Celestia."

"That's Princess Celestia to you. I would rather not be on a first name basis with a monster like you." The princess of the sun stated sternly.

"What crawled up your ass and died?" Jack asked and Princess Celestia stared at him as if she were trying to burn two more holes into his skull and Jack just laughed.

"I'd just prefer if I wasn't in the presence of such demons and monsters." Princess Celestia said.

"Well we're the only hope you've got." Jeff said. "You think that Zalgo is going to hold anything back? No. He's not going to stop until either every sapient species on this planet is dead or enslaved." Jeff walked straight up to the Solar Diarch's face and stuck his finger in right in front of her muzzle. "So you are going to do one of two things. You can quit bitching about how we're demons and monsters and all that other shit. Or you can leave, it's as simple as that."

The solar princess squinted at Jeff. "You have some nerve talking down to me like that. I am the ruler of this land."

"Last I checked I didn't have hooves, so you can take that fact and shove right next to the thing that died in your asshole." Jeff said. "We're the bad guys, yeah. But Zalgo is a different level of bad. The only thing that Zalgo cares about is death and destruction, it doesn't matter who will stand in his way to get it. Right now we are the only hope you got. Like it or not."

Princess Celestia breathed deeply and then let it out. "Alright Jeff, what's the plan?" Celestia regretted asking this but Jeff's logic was foolproof, and these beings knew Zalgo better than anyone. If anyone could find Zalgo and beat him, it would be them.

"Here's the thing, Zalgo loves to play from the shadows. He manipulates and strikes bargains." Jeff said. "Which means he'll go after the weak and desperate, he'll go after your enemies, your rivals, anyone or anything that has been wronged or wants power."

"He may have been here long enough to start assembling his army." Slender said. "Which is why we can't allow anyone to be corrupted by Zalgo."

"So what do we do?" Luna asked.

"Let the public know about the symptoms and to be wary of ponies with the disease while we're working with Evil on the cure." Slender, "Though in order to help develop a cure faster we need the blood of a pony showing the symptoms."

"That may be difficult." Celestia said. "But if it could help us then I would accept it."

"That and it can help make an shots to strengthen everyone's immunity to Zalgo's corruption." Ben said as he appeared, behind both the princesses which he startled.

"And you are?" Celestia asked.

"I'm Ben." He said. "Right now I'm the smartest one in the room."

"Excuse me? I've been around thousands of years!" Celestia said offended.

"Do you have a network of all the information of everything ever recorded in your head?" Ben asked.

"Well... no." Celestia shied down.

"I have a literal universe in my head." Ben said as he started to lay out the plan.

Jeff quietly snuck away into the old castle's garden, or what was left of it. He was thinking about what Jack said. "I have changed, but why?"

"I think it's because of where you're at." Twilight's voice added and then the unicorn in question appeared.

Jeff looked at her, "How'd you find me?"

"I saw you when you left." Twilight said. "Why did you leave?"

"I'm thinking about what Eyeless Jack said." Jeff admitted.

"What's so bad about that?"

"Because he's right."

"What's so wrong about being different?"

"Because it's not who I truly am." Jeff said. "Before I came here, I would have jumped at the chance to slice Fluttershy to pieces. But something stopped me, I still can't place what."

"Your other side." Twilight said. "The innocent one."

"Jeffery?" Jeff said.

"Jeff, look. I know that you have some sense of judgement. Maybe that stems from the time before you became who you are now." Twilight suggested.

"It's just. Not me, not anymore."

"I don't know how to help you then." Twilight said.

"No you can't. But I know who can." Jeff smile widened.
