Donna Noble wasn't exactly a hard partier. Sure , she enjoyed them. She drank more than one was necessary, and she did have some spectacular nights in her past. Going to the pub every night was new, though. Lately she had been having horrible headaches and a general sense of missing something. A great, huge, cosmic something that she couldn't remember. Things had been better, though, ever since she met that new bartender.

"You look horrible, Donna," Harry Smith said as the red head flopped onto the barstool.

"I had another bad day," she said with a groan, hitting her head against the counter.

"What was it this time?" he asked sympathetically.

"Dreams," Donna explained, waving a hand in the air. "Filled with bees and wasps and giant spiders. I think it's cosmos telling me to fumigate the flat again."

"Yes, Donna, the Universe wants to make sure you don't have any earwigs in your bathroom," Harry teased.

"Oi, that was one time!" Donna snapped. "I didn't tell you that to be mocked!"

Harry grinned. "I don't know why you trust me with anything. It's been, what, three months?"

"You have a trusting face. Reminds me of the ex-PM, but everyone trusted him didn't they?" Donna squinted at Harry before wincing as a wave of pain roared through her head.

"Something wrong?" Harry asked, eyes flickering.

"Just another one of my headaches," Donna replied, closing her eyes until the pain passed. "Sorry, what were we talking about?"

"Do you trust me, Donna?" Harry asked, sounding serious.

"What? Of course I do. Why?" Donna asked, frowning slightly. Some instinct, somewhere deep inside her, told her that the answer should have been no. But that made absolutely no sense because Harry had never been anything but charming. He had listened to all of her problems and helped her through more than a few of them.

"My shift gets done in ten minutes. Meet me out back?"

"Harry," Donna sighed. "I'm not looking for a relationship. After Lance was killed by that Christmas Star…"

"Donna, it's not a date. I want to show you something. Platonically," he added, seeing the look on her face. She looked at Harry's innocent smile, his crisp white shirt flopping untucked over black pants and sighed.

"Fine, but you're paying for drinks tomorrow," Donna agreed with a sigh before turning away, making a quick call to Granddad so he wouldn't worry.

"You be careful, Donna," told her before she hung up and Donna rolled her eyes. Him and Mum had been jumpy lately. They wouldn't even let her watch the news, claiming they were tired of all the alien coverage.

"Donna!" Harry called from further down the alley. Donna walked over to him, glancing at the tall blue box he was standing next to.

"A police box?" she asked, raising her eyebrows. "You wanted to show me an antique?"

"Not an antique, Donna," he said. "Look familiar?"

"No." Donna eyed him suspiciously. "If you try to kiss me I am going to slug you."

"Go inside," said Harry, holding the door open. Donna rolled her eyes and obeyed, wanting to get it over with so she could leave. She walked through the doors and stopped, dumbfounded. She was in a small black room with a few red couches along the corner and a tall grey panel in the center covered in buttons with a long tube in the center running up into the ceiling.

"Getting anything yet?" Harry asked, closing the door and coming to stand beside her. "No? Nothing?"

"What?" Donna asked, frowning at him. He sighed and walked over to the round panel in the center of the room.

"Maybe this will help," he said, pushing some buttons. "I'll set the desktop to Coral."

And then Donna Noble remembered Everything.

It blindsided her, all the memories rushing back with one swoop, leaving her eyes watering and her mind burning.

"What the bloody hell was that for!?" she shrieked at the man she now knew to the Master. "My brain can't support the Doctor's mind!"

The Master gave her a dirty look. "You remember my face but you don't remember my brilliance. Well, at least it tells me what the Doctor thinks about."

"Well what are you planning to do?" Donna demanded, gasping as another neuron in her head misfired. The Master flicked a switch on the console and Donna looked up to see the Chameleon circuit dangling above her head.

"It'll hurt," he said, taking a silver locket out of his pocket and plugging it into the machine, "But it's less painful than dying."

He was right and Donna knew it. She grabbed the helmet and shoved it on her head, bracing herself as the Master hit the switch.

Her world dissolved into blinding hot pain and she knew she was screaming.

Then it was over and the Master was gently sliding it off her head before handing her the locket.

"Your human consciousness is in there. Be careful with it."

Donna grabbed it out of his hand, glaring. "What is this all about?"

"What?" the Master asked innocently.

"I have the Doctor's memories of you," she reminded him. "I know you're not doing this to be nice. What do you expect me to do?"

"You know the Doctor's dealt with the Chameleon Circuit recently," the Master began, walking over to one of the coral pillars and retrieving his black suit coat and tie. "He remembered it. Why didn't he use this solution instead of wiping your memory?"

"I only have his memories from before the metacrises was created, not after," Donna snapped.

"Because," the Master explained, watching her, "He likes to run away from his problems. He doesn't deal with any of them. Not me, not you, not Rose."

"Rose?" Donna asked, suddenly feeling uncertain.

"Oh, yes," the Master waved a hand. "I paid a visit to her earlier. The point is he wants to run away. I want him to have to deal with them."

"Why?" asked a very suspicious Donna.

"Because he never has to pay for his actions," the Master hissed, a crazed light coming to his eyes. "Just once he should finish what he started. See that he can't run away all the time and still act like the solitary hero."

"Where do Rose and I come in?"

"Rose was someone he… chose to love. He knew that she wanted him, but he didn't want to be tied down to one place forever. What does he do? Kill two birds with one stone. He gets rid of his metacrises by handing him off."

"He was giving them a happy ending!" Donna protested.

The Master snorted. "Hardly. If he loved her, he wouldn't have forced her to stay with him. He left forever, didn't he? It was human or bust. He can't hold on to love for too long. He get's bored."

The last few words were especially bitter, and Donna filed away the memories that flew up to look at later.

"You want me to help you punish the Doctor for moving on?" Donna scowled. "Not bloody likely. I'm not going to help you start anything."

"I already took care of Rose," the Master replied with a smirk. "It was pathetically easy."

"I don't know what you're planning," Donna said after a pause when the Master looked at her expectantly, "But I'm not helping."

"Donna, I suggest you reconsider," the Master warned, his eyes darkening. "I haven't forgotten that you're part of the Doctor."

Donna fingered the pen in her pocket. "You brought me here just to kill me?"

"Not with that purpose," the Master said, drawing his laser screwdriver out of his pocket. "But having you as a… guest might help me gain leverage against the Doctor."

"You know what the problem with completely Time Lord brains is?" Donna asked, tensing. "You can't be creative. I mean, the Doctor was good at getting out of these situations, but I bet he'd never do this!"

Donna slammed the pen down, wedging it into a tiny but disruptive gap. Sparks flew out of the console and the Master was forced to reach for the controls. Donna turned and threw her weight against the door, bolting out across the alley as it gave way. She turned down a number of streets until she was sure the Master couldn't find her easily. She paused in an alley, leaning against a wall as she caught her breath. Inwardly she cursed in English and another few languages she didn't quite understand before stifling a scream.

She needed to get to Rose and find out exactly what the Master did.

She needed to find the Doctor before the Master did.

"The cell phone!" Donna realized, remembering the small device that always lay on the console. She wracked her brain before groaning as she realized the Doctor had never bothered to learn the numbers. Right then, new plan.

She needed to find Martha Jones.
