"The brain is a lovely organ. No pain receptors. And humans only use ten percent, which leaves plenty for us."
"I prefer the heart. So many wonderful things come from the heart."
"It is too easily broken."
"Joy, hope, determination, all these things come from deep inside our souls, and if the brain is gone, so is the heart. Have you no thought of what these people might turn into if you wipe them out? In three centuries, your people could be wiped out by a plague that only the humans have a way to solve! You're signing your own death warrant!"
"You are in no position to beg for your people."
"It's too late for that, anyway," said Deora solemnly. "They're long gone. But the humans! They're just beginning to flourish! You have no idea what you're doing when you do this!"
"We eat. The brain provides sustenance for our people."
"Is it the actual gray matter, or what is held inside?"
"Both."
"Take mine and leave these people alone."
"What makes you feel you can make up for the whole planet?"
"I'm a Time Lord," she said simply and softly. "The last Time Lord."
The Doctor turned to the Diaglosian captain.
"Why don't I use your ship?"
"Iweourme shipvehicletransport?"
"Yes, your ship-vehicle-transport-thing! I've got to save her! Come on!"
They boarded the Diaglosian ship, and the Doctor automatically headed for the control room. He felt heavier than he had on Earth, and it was no wonder: Diagloss had a mass one and a quarter the size of Earth, and subsequently the gravity was proportional.
"Set scanners to full range! We're looking for Logasmalite ships."
"Whowhatwhy is thisthat manhumanmale?"
"Friendhelperally."
"Oh, there she is," said the Doctor with a hint of cold malice in his voice. "There's the ship that stole my last hope. I'm going aboard."
The Logasmalite laughed, and it sounded like a thousand worlds exploding as heard from underwater.
"You're a Time Lord?" The laugh again. "A Time Lord? The last Time Lord? I had heard that one survived the war, but you? You're a child!"
"A two hundred year old child. I have all the knowledge of the Time Lords stored in my head-I'm a walking library of Gallifrey. But I will fight back if you do not keep your promise. I have friends who will avenge the Massacre of Earth. They'll kill you. They'll hunt you down to the farthest reaches of the galaxy and the universe, and they will not stop until every one of your people is gone. And it will not be a simple death, either. They'll make it so painful you wish you had never heard the word Earth. Oh, yes, the Daleks know about that revenge. They were on the wrong end of his anger. Kill me if you like. But know that it seals your fate."
"First you offer nothing but trouble. Then you offer your brain, and now you threaten us? Are you quite decided? I am. The human race will become our feeding ground, and you are our appetizer."
Deora swung around in anger, breaking the bonds holding her. As she fell to the ground, she managed to wheel herself into position to kick the captain in the place it hurts most, jabbing the heel of her boots hard into him. And from there, it looked like some martial arts movie gone sci-fi, her black clothing acting like a cloak around her. The Timeshadow fighting the brain-eater. She grabbed a pipe from the wall and used it to fight the creature. She knocked him unconscious, but he was badly hurt. His fire-orange blood was all over her clothes and face, and it was matted in her hair.
"And he won't be the only one to fight you," she said as she dropped the pole. She ran to the nearest console, pulled out her homemade sonic screwdriver (smaller than the Doctor's, but no less effective), and jammed it into the computer system. Instantly, Thoughtless by Evanescence began to play, its loud guitars and harsh lyrics filling the com system of the ship. She turned to intership communications and turned it on.
"This is Deora of Gallifrey to any nearby ships," she declared. "If any of the Logasmalite people set foot on Earth ever again, you will feel the fury of all the lost Time Lords, channeled through me. Do not attack these people ever again or you will not live to tell your grandchildren about the anger that one Time Lord can possess. Leave this solar system now and never return. Understand this well. If you violate this, you will regret it."
She waited for a few precious seconds, then turned the sonic screwdriver and pulled it free. ("I will not be won by your thoughtless scheming…") A timer displayed on the monitor, and she stood up, briefly bathing herself in the music.
"That should do it," she said, and took off for the nearest escape pod.
The Doctor had not seen the transmission. He was busy complaining to the Diaglosian captain about their lack of small rescue craft.
"What do you mean, you don't have a shuttlecraft? How do you get to the planet?"
"Transmat."
"But they have a shield blocking transmat beams!"
"Yesaffirmativecorrect."
"Well how am I supposed to save her?" He was yelling at the top of his lungs.
"Unknownclueless."
The Doctor proceeded to kick things after that. She was gone and there was nothing he could do about it. He'd lost her. There was nothing he could do.
And then the Logasmalite ship exploded.
