The Doctor dreamed. Well it was a memory. He remembered something, that he found irrelevent, but meant so much now.
He was back on Gallifrey, in the Academy. He was sitting in the classroom, listening to a story he had always found interesting. On Gallifrey there was an animal, similar to the Wolf on Earth. They called it the Xolf. It was a creature with gold and blue eyes, and could bend the Vortex. According to the story, there was a Time Lady, who was born several hundred years ago. She was born with the power of a Xolf. She could pull beings out of time and space, rip anybody apart with a wave of her hand, teleport, turn invisible, you name it, she could do it. One day her family was slaughtered. Her own kind betrayed her, the Xolfs found her family, and tore them apart. Just because of her power. She went mad with grief. She ripped the Xolfs apart. She was the only one left who had the power of the Vortex coursing through her veins. When the Time Lords heard of her tearing her apart the Xolfs. They tried to arrest her. She killed those who tried to arrest her. She went into hiding, she didn't want to be arrested, and she didn't want to kill anymore. The Time Lady hid for 300 hundred years.
One day she finally left from hiding. She wanted to be forgiven for killing the Xolfs and a few Time Lords. She was forgiven, but with a cost. She would have to protect Gallifrey for all eternity. She agreed. She defended Gallifrey for hundreds of years, until one day she couldn't be found again. The Time Lords were in outrage, she broke her promise, and now Gallifrey was undefended. One day, a few years later Gallifrey was surrounded by the Sontaran Empire, they were about to charge into battle, and the Time Lords were doomed. Right before they were about to attack, all the Sontarans turned into a golden dust. The Time Lady appeared and saved them. After this, she disappeared. She only appeared when needed after this occassion. Whenever asked why she doesn't stay she says "I must defend Gallifrey untill the final War. Then, I can't defend you." then she would disappear. She was given the nickname of the Defender Xolf.
The Doctor slowly came around from his memory of a story. He saw two concerned faces over him. His eyes focused on them, and saw Amy and Rory looking down on him, on the floor, where he passed out. "Doctor, are you alrigt?" Amy asked. "Yes, I'm fine... I uh" he paused looking around to see where he was. Rose's room. He sighed. This was still considered sacred property, and now Amy and Rory were tredding upon it. "Nothing. I just hit my head. Now please leave, I have buisness to attend to." he said calmly. Amy and Rory saw anger and sadness in his eyes. They did not want to make those emotions arise, so they left.
Once they left, The Doctor stood up, balancing himself. He slowly spun back to the drawer. He looked in and picked up the object. He spun it around in his hand, and inspected it. It really was a Fob Watch. Another Time Lord escaped the War! Rose was a Time Lady. The Doctor was happy and excited. Then he realized where Rose was. The Parallel Universe. With his close. He sighed. He thought back to earlier, Rory's water bottle. It said two words. Bad Wolf. Does this mean she's coming back? The Doctor flipped the Fob Watch over in his hands, to read the back, where it should say the Time Lady's name. His eyes promptly widened in surprise, and dropped it in surprise. His breath increased, he reread the name, again and again.
The name read: Defender of Gallifrey, Xolf. The Doctor set the watch on the desk, he thought about this, Rose was the legendary Defender of Gallifrey. Suddenly he made the connection. Defender Xolf, Bad Wolf. A Xolf is similar to the Wolf. How did he not see this?! He suddenly was outraged, why didn't Rose defend Gallifrey during the Time War? She obviously had the power! She left him to destroy Gallifrey! His breathing became laboured. He realized he had to get the watch back to Rose, to find out. He knew the Bad Wolf was reappearing, and he couldn't break the walls of the universes. He was just going to have to wait for Rose. He put the fob watch in his pocket, he heard a voice, double layered coming from the watch "Bad Wolf" it said. The Doctor smiled, he knew he wouldn't be waiting long.
