Riley

William swung Murphy at Linda, slicing her arm open.

"William!" I shouted, tackling the grey-haired teen on the ground. But I underestimated how strong he was, and he kicked me off, sending me against a wall.

"Murphy! Stop fighting!" I shouted, running at William again. Then, I noticed something. I knew what was going on. "How'd you two get black-blood?"

William smiled, holding his hand over his mouth as Murphy changed back into a human, holding a large knife-wound and laughing.

"I got stabbed," Murphy said after a few tense seconds of laughing. "I got stabbed by Linda, 'cause you killed Medusa. Linda is insane, Dad. I was gonna die, then William helped me. I've got your blood, now. William's got Soul's."

'Stein, that sneaky, creepy bastard.' I thought.

"Murphy, calm down. The black-blood isn't that-" I stopped as Murphy's arm changed into a long, crooked scythe. "Try attacking me, if you want. I'll knock you out." I said.

Murphy laughed, and jumped at me, scythe leveled at my head.

I ran into the school, looking for anyone who might know where Riley was. And I saw Dr. Stein, and immediately ran to him, grabbing him by the lapels.

"Stein, what's going on?" I asked.

"It seems William has gotten into two vials of infected blood I had." Stein said. "I had forgotten about them."

My grip tightened. "Infected blood?"

"Yes. From Soul and Riley. It's infected with black-blood, from before Soul and Riley conquered their demons. So to speak." Stein said.

I tossed Stein away and ran to Maka.

"Riley's in there," Maka said, pointing to the gym. I ran inside, and saw Murphy attacking Riley.

"Rye!" I shouted, and Riley turned.

Just in time for Murphy to stab him.
