Extend the Story - Add a Room

You got onto your feet and ran as fast as you could to catch Goju. You stayed in the darkness to conceal yourself, but run you did. Before you long you had caught Goju and were running alongside him. You hadn't realised where he was going at the present time but you kept on following him.

He arrived at a door. Here you walked into the light.
"Goju. Stop running. I am trained far better than you. You are only a Master. I on the other hand took my training seriously and bettered all my skills. I am faster and stronger than you. I can hide faster than what Druin Biza could. So give up."
Goju looked at you. Then he turned and banged on the large, double wooden doors. He gave 5 fast knocks. It was the emergency knock.
You knew that you had to get out of here, or kill Goju to survive. What will you do?

Kill Goju. Like NOW!
