Creepypony

Star teleported to the main lobby and gasped. Since the last time she was here, the infected were escaping and banging on the walls, but now they were gone. No cracks, no magic blasts on the wall, nothing. She looked around the room and saw the portals were still there. Her only guess was that the others defeated their demons, so she trotted out od the room through the secret passageway. Star almost began to whistle a tune, but stopped in her tracks when she saw....Apple Cinnamon, Sunny Flicker and herself walking down the hall towards her.

What the hell?  Star thought. Apparently she was going back in time. But if those were the past selves, that must mean that the others were still in the portals!

Star ran back to the wall and opened it. She anxiously clopped her hooves when the door stalled, but after it opened, she ran through. When she got to the room, a problem occurred to her. Which one would she go through? Would she save Sunny, her sister, first, or Apple Cinnamon, a new friend?

Star couldn't decide, so she closed her eyes and turned in a circle and picked a direction. She entered the portal before her and felt herself being teleported, a feeling she hadn't felt in awhile.

When she appeared in the town, ponies in white armor ran at her, pointing their guns at her. She stood up tall and waited for them to strike or get too close. From the side of her hair, she drew out the cat's paw. Celestia, I love you, Pinkie! She thought grimly to herself. Only Pinkie would think of this.

One soldier drew nearer a that the rest and prodded Star with his gun. In an instant, Star flew into action. She slashed at his neck with such force that she cut it completely off. The way she jumped from each soldier , it was like following a blur she was so fast. Soon Everypony around her was dead. She wiped her blades on a random pony's clothes and moved on. Just like the old times, she thought as she walked.

Apple struggled to stay awake before the next surge of electricity went though him. He couldn't do this much longer...he could already feel his life start to melt away.

Suddenly he heard screams and gunfire outside. One of the guards protecting Apple's machine had a three-bladed tool thrown at his head, killing his instantly. Apple looked up in surprise to see Star Wishes standing in the doorway, breathing hard. She walked over to him and janked the fluid tube out of him, leaving the tube sucking blood out in. How did she know...?

She started working on his strapping, only to get flustered and give up. She pulled the bladed tool out of the soldier's head beside him like it was made of butter, and cut all of Apple's restraints off with a flick of her hand. Only then did she take out the blood tube.
