Guess who's back! hope yu enjoy

The first few weeks he orbitted a sun, never leaving the captain's seat. He never took his eyes of the mobile phone he had got from Martha in case she needed him. After he was able to at least temporary surpress his feelings he went whereever the TARDIS sent him; where he was needed.

He spent months saving planets he didn't care about; people he didn't want to know. It was getting harder to walk out the TARDIS,to smile when he saved a planet or even galaxies with every day he didn't see her. He was far away from earth, too far for their still young bond to connect them. He felt horribly alone. More than just once in a minute his hand would wander to his chest pocket where he always carried the phone.

He was in the TARDIS when it rang. He answered at once not even bothering to look at the display.

"Hello?" He asked.

"Doctor?" he sighed as he heard Martha's voice. "Doctor, we need your help." She was working for UNIT together with Mickey.

"What's wrong?" He asked.

"We don't know... it's a strange alien signal and I just can't figure out what it is... I'm sure you'd do better! I'm in London." she explained "14th September 2009." she added, remembering that he could travel in time.

"Stay on the phone. I'll link the TARDIS onto your signal." He said and connected the phone to the control panel.

Seconds later he materiazied in Martha's office in the UNIT building in London.

"Hello, Martha" he said forcing a smile. He feared she'd ask for Rose but she didn't. He figured Mickey must have heard what happened and told her.

"I'm sorry about... Rose...and your child" she said slightly feeling uncomfortable.

"I'm alright." He said. They both knew he was lying ad she decided to not mention Rose anymore. She saw only the sound of her name hurt him. "Well then... the aliien signal" He reminded her after a few moments if awkward silence. She nodded and guided him to a room full of computers. He looked at the big screen on the wall opposite to them. They were still trying to track the signal. He walked over to a deserted computer and adjusted the tracking settings.

"That's not a signal like from a spaceship or something like that. That's a live signal... but it's strange... it's..." He didn't find the right word. He pulled out his sonic screwdriver and pointed it at the monitor. "I'm changing the wavelength so we can see it properly-" he stopped as the signal got clearer. How could that be?! This was impossible.

"Doctor, what is it?" Martha asked. "We haven't picked that signal up, yet. It's not in our index."

"Of course it isn't. This signal is not meant to be picked up. Usually it's guarded by a genetic code sealing it from the rest of the universe, never to be seen or heard. A silent watcher. But this one's unprotected..." He muttered "But how can he even exist?!"

"Doctor, I have no idea what your talking about..." she said. he grabbed her shoulders. "Track the signal. Call me as soon as you have."

He said and ran back into her office into the TARDIS. He had seen that life signal before and that didn't end very well. The only thing he could think about was Rose safe inside the TARDIS. He materialized on the court he had been so many times and ran up the staircase. Jackie opened almost at once when he knocked.

"Doctor..." she whispered.

"Where is she... how is she?" he asked.

"She's in the living room. She hasn't talked much... she's not responding if I ask her something." His hearts sank but right now the only thing he wanted was her to be safe.

"I'm sorry." He said as he hurried past Jackie into the living room. Rose looked at him. The full power of their bond hit him. It had weakened due to their separation. "I'm sorry, Rose." He said and scooped her up. she tried to fight him off, tried to escape his firm grip. "Jackie. Into the TARDIS. There is an emergency. I need everyone I love safe and where I can protect you. I'll explain later." He hurried down the stairs.

"Let me down!" Rose screamed.

"I know, love. I just need you safe! I need you where I can protect you. I need you alive. I just need to know you're okay." He said and finally reached the TARDIS.

"But I'm not! I'm not alright" she shouted as they were finally inside the control room. "Now let me down and never touch me again!" she was starting to sob. He let her down as Jackie entered the room and locked the door. His mobile rang.

"Martha?" he asked. "Do you have the signal?"

"I'm not your human friend." the Doctor's eyes widened in shock as he recognized the voice answering him although it was a totally different voice.

"What have you done to her?!" He shouted into the small phone.

"Oh she is quite safe... well as long as you come here... with your TARDIS, oh and I've heard you're married." then the connection was broken up. The Doctor ran through his hair.

"What is happening, Doctor?" Jackie asked.

"It's hard to explain... I just... just trust me." He said. Jackie was fine with that and she was also pretty sure she wouldn't understand.

"How could I?" that was Rose. He whirled around.

"Rose..." he started.

"How could I trust you after all you did? How could I trust you when you promised me everything and then just tricked me and took away my child! How could you hurt me like this and expect me to just forget it?!"

"But I'm not!" He said and took a step towards her his fingertips almost brushing her cheek "I'm not expecting you to forget it... I expect to understand why I did it."

"You wanted to save me...I understand but I didn't need to be saved." she said.

"I wanted to save you because you're the only reason I'm still alive. When we met first, I was lost and lonely. I killed my people and there was you and you were perfect. That innocent, brave, curious human. You made me better. You changed me. From a warrior into a savior. But no matter for what reason, I'm a murderer. I murdered as I faught in the war and I comitted genocide to my own race. I betrayed the name I chose when I was just a kid. The Doctor. More than a title; an oath. What do you think happens to someone who breaks an oath he lived up to for centuries?! I nearly died killing all those people. You took that horrible guilt from me. I'm selfish. I needed you to live to make sure I could go on; to make sure I hadn't had to feel that guilt again. It just grew... my guilt grew cause I killed again. I betrayed my name again and I lost the only thing keeping me alive... I lost your love." His voice was shaking and a tear rolled down his face "The only thing that kept me alive for all those months was the possibility of you calling. I hoped for this phone to ring every second and every second it didn't ring I was closer to death." He looked down. "I can't do this anymore. I can't wait any longer. Refuse to believe in me; refuse to love but know, Rose Tyler, that it will send me to my grave." Then he turned to the control panel, shuting his mind from her emotions and started to pull levers moving the TARDIS to the UNIT control centre.

As they stood still again he turned to Jackie still standing at the doors of the TARDIS.

"Jackie. As soon as I leave this ship you lock the door and you let nobody except me and Martha in here. You got it?" Jackie nooded and he handed her the TARDIS key.

"Doctor?" she asked "What is happening?"

"It's the Master."
