"Central Commander," says the Doctor as he stands up. "End this war."
The Central Commander turns around and sees the Doctor.
"Who are you? How did you get here? Guards, on my position at once!"
"I am unarmed, Central Commander," says the Doctor as he holds up his arms.
"I see," says the Central Commander.
"Doctor, what are you doing?" asks Clara.
"Doctor, she said? What type of Doctor?" asks the Central Commander as the guards swarm in.
"I come from Gallifrey. I am a time traveler. The enemy you are facing I have faced for thousands of years across my lifetimes. My battles with them have resulted in countless loss of lives – including that of my own people. I had to seal them away to save everything, but I lost everything."
The Central Commander looks at his troops as they stand ready to fire upon the Doctor and Clara.
"And you, young lady….what's your name? You travel with this man? Why?"
"Clara Oswald, the Governess. Because I trust the Doctor with my life."
The Central Commander is moved by Clara's words. "Doctor, how do I know you are telling the truth? Were you sent from the Kaleds?"
"I was sent from the Kaleds – but I was responding to their distress call. Davros had sent me to steal what you are using now….but I won't."
The Central Commander seems bothered but relieved at once, "At least you are forthcoming. Scan his mind for the truth. It may hurt momentarily."
A guard steps forward and holds up a device that scans the Doctor's mind. The Doctor cries out in intense pain and Clara grabs his arm.
"It checks out. He's telling the truth," says the engineer holding the device.
"So I see that you are telling the truth. You know what the device I'm is?"
The Doctor responds, "No, I don't – tell me."
"It is a symbiote. Every commander of the Thals forces has used it over the years. Any citizen of Thals can use it – but it seems to pick its host. We found it here on Skaro. The metal harness is used to protect the host. We found that the symbiote has the capacity to drive its user insane, hence the metal harness."
"So it all makes sense," says the Doctor.
"Obviously Davros thinks what I'm using will help him. It will but at a great cost. In order for this to work, I would need to have the Thals being willing to die for me and trust in me to let their actions be guided."
"Oh no," says the Doctor.
Clara looks at the Doctor concerned, "What's wrong?"
"Then when Davros got the symbiote – it did make him crazy. It gave him what he needed to make the Daleks functional. But they became just as insane as their creator."
Davros arrives with his troops while the Doctor comes to this realization.
"Now you know why I no longer need you Doctor….execute him and seize the device!"
"Protect the Doctor and Clara, soldiers!" says the Central Commander as his troops stand in front of the Doctor & Clara. "Doctor and Clara, get behind me!"
The Doctor and Clara move behind the Central Commander as a fire fight ensues. Davros lunges forward from his wheelchair and tackles the Central Commander. A struggle ensues on the floor of the Central Command chamber. Davros grabs the blue symbiote from the Commander's forehead and pulls it out.
"No Davros, don't do it! You don't know what it will turn you into!"
"Yes, I do Doctor. I will become Death, destroyer of worlds," says Davros as he holds the symbiote over his forehead.
The symbiote scans Davros and enters in. Davros jerks around as the symbiote settles in his forehead. One of his soldiers puts the metal harness over Davros' head. Some of the remaining Kaled soldiers help Davros back to the wheelchair.
The Central Commander, bleeding from the forehead, gets up and quickly moves toward the Doctor & Clara.
"We have to get you out of here! Now!" he says as he opens a secret door. All three head out through the escape route.
Davros' facial expressions change the symbiote takes control. He is in obvious pain then he…begins to smile.
"Yes, I can feel the power! This is an ultimate power! I have become beyond a mere man….I have become a god! I have become a DALEK!"
"What are our orders, sir?" asks a Kaled soldier.
"Find the Doctor! EXTERMINATE! EXTERMINATE! EXTERMINATE!"
