"I want to make a deal with you, Twilight Sparkle."
Twilight was initially confused at this at first since it was pretty sudden. They had only just met and he wanted to make a deal with her? It sounded suspicious to Twilight. Twilight Sat down in her chair as Bill lowered himself next to her.
"What is it, Bill? Everyone's gone and I'm tired!" Twilight told him.
"I know, I know, so I'll make this quick. You understand that I'm from another dimension, right?" Bill asked her.
"Yes. Where exactly are you going with this, Bill?" Twilight said, cautiously.
"Well, I overheard your friend mentioning that another friend of yours, Starlight was it, had left just before I came and that gave me an idea. What if I bring your friend back...permanently!" Twilight's jaw dropped at the idea. She didn't want Starlight to leave in the first place. If Bill could bring her back, then she wouldn't have to say goodbye again.
Just then, Twilight began to become a little suspicious of Bill. "Wait a minute, why are you doing this for me? You aren't even from here."
"Well, I thought that we were friends and I wanted to do something for you for letting me stay here for a couple of days!" Bill seemed a little too excited about this deal.
"I don't know, Bill. I mean, what exactly is it you want in return from me?" Twilight didn't really want to know the answer, but if it was to have Starlight back...
"Oh, I thought you'd never ask! All I want from you is a bit of control for a short while. I want to go inside your mind!" Bill was starting to become more and more eager with every word.
"You want to control my mind!? That's crazy! I don't even know if I can trust you properly and you want to do something that could potentially destroy Equestria with your kind of power!" Bill wasn't too happy with this response.
"WHAT! ....Okay, Twilight. If you don't want Starlight back, that's fine. You will never see your friend again."
"Not exactly, We're still allowed to visit. Now I'm going to bed. You should too...if you can." Suddenly, Bill began to laugh behind her.
"Are you serious, Twilight Sparkle! I'm an interdimensional being that can bend the will of reality! Here's the thing, Twilight. If you don't agree to this deal, you friend will die! PAINFULLY!" Bill was serious and Twilight knew it.
"Rainbow was right about you, Cipher." Twilight suddenly turns around and shoots a beam of magic at Cipher which he then stops in mid-air. Twilight was not expecting this.
"Is this a joke, Princess!? You think that's going to get rid of me that easily!" Bill shoots the beam back at Twilight who falls to the ground on impact. Bill notices Spike coming down the stairs and into the main room.
"What is going on in here? It's so late right now!" Before Spike had a chance to realise what was going on, Bill gave a snap of his fingers and lifted him up next to him.
"No, Spike! Don't you even think about it, Cipher!" Twilight was furious, scared and frustrated right now. "Why would I make this deal with you now after EVERYTHING that has happened here!?"
"Well, not only will I kill your friend Starlight, but I'll kill your little friend here, and all of your friends out there! Now MAKE THE DEAL, TWILIGHT SPARKLE!" Bill yelled, prepared to kill Spike at any moment.
Twilight attempted to teleport out of the castle to get help. Unfortunately, it was no use. "What is going on? Why can't I leave!?"
"I've blocked every entrance and exit here, even trying to teleport yourself out of here won't work with me around. YOU'RE OUT OF YOUR LEAGUE HERE! JUST MAKE THE DEAL AND NOBODY DIES...YET." Twilight couldn't bring herself to risk Equestria like this, but what would happen to Spike?
"I can't. You will destroy Equestria and I can't let that happen!" Twilight knew what this meant, but she wasn't sure if she made the right choice.
"Twilight, please! Help!!" Spike begged for help, but Bill wasn't having it.
"I'M GETTING TIRED OF YOU, SHORT STACK!!" Bill snapped his fingers once more and Spike's neck began to twist until Twilight heard the crunch that she dreaded. Bill had snapped Spike's neck. He then dropped Spike's corpse down in front of Twilight.
Twilight was in tears over her assistant. She didn't know what else to do. If she didn't make the deal, Bill would kill Starlight and who knows who else! And if she did, Equestria was in serious peril.
Bill moved down to Twilight's level. "So, are you going to make the deal or not, My Little Pony? Do whatever you want, people die either way!"
Twilight ran upstairs to write a letter to Princess Celestia. She needed help. Bill noticed this and ran after her.
Dear Princess Celestia,
I thought that Discord was the weirdest thing in Equestria, I was wrong! This creature came through the mirror portal called Bill Cipher. He is dangerous and he murdered Spike right in front of me! He'll keep killing unless I let him take over my mind. Please help, we need you! My friends won't ever forgive me if I give in to him. Come soon.
Your Faithful Student, Twilight Spark▲▲▲
"YOU SHOULDN'T HAVE DONE THAT, YOU INSOLENT LITTLE PUPPET!"
Twilight had managed to send the letter just before Bill had reached her. "There is nothing else you can do to me that will make me change my mind, Cipher!"
"If you say so!" Bill did it. Twilight thought that she could call his bluff but Bill showed her a bubble which showed Starlight at her town. As soon as he snapped his fingers, Starlight began to shake vigorously before finally being incinerated into ash. The bubble also disappeared .
"How did you like that, Twilight! That was my best work yet, NOW MAKE THE DEAL!" Twilight could not believe what she was looking at. Her friend who she wanted back more than anything was dead. She needed Celestia to get here right now but she didn't have a choice.
"FINE! You've murdered two of my best friends and I've lost, are you happy now!?" Twilight had lost all hope at this point unless Celestia comes soon.
"Very." Bill held out his hand, ready for the deal to commence. Twilight held out her hoof and began to shake with Cipher. Once they had made the deal, Twilight heard someone. It was Princess Celestia along with Luna and several members of the royal guard.
"Twilight! We're here to help! Where is this Bill Cipher!?" But it was too late, Twilight had made the deal and Bill was ready.
"Oh boy, THIS WILL BE FUN!" Bill was now inside Twilight's body, he had control over one of the Princesses of Equestria. Imagine the power he could have!
At this point, Twilight's castle began to shake...a lot. It began to crumble and it was being destroyed. Celestia did not know what to think of this. "What is happening!?"
Twilight's castle had been destroyed. Spike was dead. Starlight was dead. Twilight had given in to Bill. And Twilight, AKA Bill, was face to face with Princess Celestia, Luna and the Royal Guard on what remained of the castle.
"I CAN'T WAIT TO WIPE YOU ALL OFF THE FACE OF THIS PLANET!!!"
