Added a sneak peek as well
~Your author, who can't name chapters, and is 11 chapters ahead)

POV: Diamond

"What happened?!"

I shouted, as I looked at the hell-hole that was the living room. "You don't remember anything?" Emerald asked, looking very troubled. I shook my head. "Last thing I remember was the super high pitched sound in my head..." I said, I rubbed my forehead. Trying to remember was not helping my headache, I can only remember a few minutes back without hurting my head "Soo, what happened?" Emerald simply pointed to me, to the knife, her bandaged arm, and then the window (in that order).

POV: Emerald

"Soo, What happened?" Diamond Asked

~Flashback~

"M-Ma'am?"

Diamond was clutching her head, she seemed in pain. Then she started giggling. It was high pitched, and she took a super small breath every two seconds. Creepy... I was worried. Then she threw her head back, her giggles turning to full-on insane laughter. "Are you okay?!" I asked, she looked at me.

Instead of those Diamond blue eyes I know, they where crimson.

"Hey there!" She Said, her voice too happy, and high pitched. "Diamond?" I asked "My name isn't Diamond... my name is Ruby! Ruby Casket!" She shouted "W-What do you me-" I was cut short by shock as she pulled a kitchen knife out of her pocket. She was still laughing. Said kitchen knife was stained red. She jumped up and pushed me into a wall. She attempted to get me, but I dodged, causing her to slice the wallpaper. It was a perfect line. She really knew how to use a knife. Diamond- I mean... Ruby...? Grabbed my arm and said: "I'll show you I'm in control of my sanity!" Then she cut my arm. She threw her knife out the window and jumped out.

~Flashback over~

Now how do I explain this?
