She grinned. She sprinted through the halls making no noise at all. This was one of the many things that she was trained to do, as well as her species being faster and more agile than humans. 

She spotted red and orange standing puzzled at the light going out.

(Perfect) she thought, nearing the two.

She crept up behind red and covered his mouth. She grabbed her knife and stabbed his neck. His death was quick, he died in seconds.

"Red....?" Orange called out.

No answer.

Pink sprinted back to black.

The lights eventually turned back on.

Orange had heard the shuffling and the body dropping to the floor.

Once the light turned on, She slowly turned around.

She saw reds body on the floor.

She audibly gasped.

Red was coated with his own blood. Blood gushed from his neck.

Orange dropped to her knees, crying.

She lifted off his helmet. His eyes were wide with fright. He had short, semi spiky hair that went down to his eyelids.

She touched his face and let out sobs.

She hugged him, sobbing.

She had cared about him so much! How could this have happened!?

(How...?! We were together the whole time...!!) she sobbed louder.

Eventually she calmed down enough to report his body.

Everyone was transported to the meeting room to hear the news.
