Mermaid Goddess: How could I?

I walked through the streets of Port Royal. I was going to Fort Charles, to hopefully get some information on the Navy. My friend, William, walked along side me. I gave a nod and we each sprinted  to one side of the huge gates. With a single slash on the neck the guard lay on the ground, blood seeping from his wound. I looked over at Will to see he had done the same. I took a key from my guard and unlocked the gates. We stepped in the gates to see rows upon rows of guards. One Cadet stepped forward. "I see you've ordered a greeting party," I say in a mock casual way. The guards lowered their bayonets and pointed them towards me and Will. "Mermaid, we're out numbered," Will whispered to me. We both had our swords drawn. The sound of a gun shot filled the air, searing pain soarded up my arm. Suddenly I had to kill them all, in minutes all the soilders were dead, but I still had to kill. I turned toward Will, he looked horrified. ''He better be. ''I thought. The last thing I remember was sliding a sword across his neck.

I woke to the sound of someone moaning. I sat up and stared at Will. His neck had a nasty slash acrossed it and it was leaking blood. His skin was paper white. "Will! What happened?" I said. He opened his eyes and pure horror crossed his face. He scooted away and let out more moaning. "Mermaid, please, what did wrong?" He said with great effort. ''What have I done? ''I thought.
