"But how though?" Donna practically wailed. "I'm just a temp Rose! The only adventurous thing I have ever done in my life was run from Torchwood One and considering how stupid they were it's not saying much"

Rose squeezed Donna's shoulder. "Despite what you think hon you are very important to the universes design" she said calmly. "All you have to do is turn left"

"What?!"

"Alex Rose left an explanation" the dark skinned man said coolly. "Apparently something, somehow had made you turn right and accept Chowdry's job offer thus making you not meet Lance – is that his name?" he cut off looking at Rose who gave a small nod. "Who was supposed to drug you with some sort of particles that would have triggered your meeting with the Doctor"

"Who, what, where, huh?" Donna blurted out in a shrill voice.

"It's complicated" Rose sighed. "Alex Rose left a half explanation about it but basically you had to meet the Doctor and stop him and my mother from drowning that Christmas Eve"

"You need to turn left" the dark skinned man said. "Correct your mistake"

"All right who the hell do you think you are?" Donna snarled. "You keep turning up in my life, charmed my best friend and making this whacked out promises, dangling my godchildren as the bait!"

"Donna you can trust him" Rose said quietly. "I have known Mickey my whole life and I trust him with everything"

"Mickey?" Donna whispered. "As in your-"

The man himself suddenly walked off, he paused for a second and shouted over his shoulder. "Are you going to fix your mistake or are you just going to gossip for the rest of the night?"

Donna shot him a glare. "How am I going to go back in time and make sure I turn left?" she snapped.

"You always did want to see the TARDIS" Rose said quietly but amused.

DWDWDWDWDWDWDWDWDW

There was a dim light coming from the console, everything looked almost lifeless and weak but beautiful and fascinating at the same time. Donna watched Rose in interest as the weakened and tired blonde stroked a small metal blob.

"Hello old girl, not long to go" she heard Rose whisper as her fingers danced across the rest of the console.

"She's beautiful" Donna said awkwardly. "Strange but...so beautiful and fascinating and weird and..."

"It'll be yours soon" Rose said with a smile. "You'll be in here travelling with the Doctor, seeing strange worlds and saving civilisations, oh all that running to endure"

"Sounds wonderful" Donna said mostly to herself.

"Do you want to see what's on your back?" Rose asked suddenly.

There was a moment's pause before Donna answered. "Go on then"

DWDWDWDWDWDWDWDWDW

Rose had led Donna into a circle of mirrors and motioned her to stand still. "We don't know how the TARDIS works, but we've managed to scrape off the surface technology. Enough to show you the creature" she said calmly.

"It's a creature?" Donna squawked. Terrified about what could be on her back.

"Just stand here" Rose said.

"Out of the circle, please" Mickey called.

"Yes, Sir" Rose said saluting mockingly, earning a glare as she walked out of the circle.

"Can't you stay with me?" Donna asked pleadingly, but the plea was ignored as Mickey began to bark orders to the UNIT workers.

"Ready? And... Activate"

The lights around the circle turn on. Donna closed her eyes suddenly desiring to not see what was on her back.

"Open your eyes, Donna" Rose said.

"Is it there?"

"Yeah, open your eyes, look at it"

"I can't"

"It's part of you, Donna. Look" slowly Donna opened her eyes to see her back in the mirrors. There stood proudly a massive black beetle like creature clinging tightly to her back. She began to spin round in panic, trying to catch a better view of it. "It's okay, it's okay, it's okay - calm down. Donna? Donna? Donna!" Rose shouted trying to calm her friend. Donna stopped spinning. "Okay"

"What is it?" Donna asked trying to remain calm.

"We don't know" Mickey said coolly.

"Oh, thanks" Donna said sarcastically.

"It feeds off time. By - by changing time, by making someone's life take a different turn, like, meetings never made... children never born... a life never loved. But with you, it's..." Rose trailed off unsure what to say.

"But I never did anything important" Donna protested.

"Yeah, you did. One day, that thing made you turn right instead of left" Mickey said calmly.

"When was that?"

"Oh, you wouldn't remember. It was the most ordinary day in the world, but by turning right, you never met the Doctor and the whole world just changed around you" Mickey answered.

"Can you get rid of-of it?" Donna asked.

Mickey was about to open his mouth to answer but he caught Rose's look and she shook her head. Closing his mouth Mickey also shook his head. "This is not relevant to the mission" he said instead. "Power down" he shouted out to the UNIT workers.

The lights went off and Rose walked up to Donna, pulling the agitated redhead into a comforting hug.

"It's... it's still there, though. What can I do... to get rid of it?" Donna murmured.

"You're gonna travel in time" Rose replied.

DWDWDWDWDWDWDWDWDWDW

Donna stood next to Rose wearing a strange coat full of wires. She listened as carefully as she could to Rose's lecture.

"The TARDIS has tracked down the moment of intervention. Monday the 25th, one minute past ten in the morning. Your car was on Little Sutton Street leading to the Ealing Road, but you turned right heading towards Griffin's Parade. You need to turn left. That's the most important thing. You've got to go back, turn left. Have you got that, Donna? One minute past ten, make yourself turn left, heading for the Chiswick Highroad"

"Keep the jacket on at all times - it's insulation against temporal feedback" Mickey ordered as he put something that looked like a watch on Donna's wrist. "This will correspond to local time wherever you land" he then handed her a plastic cup of water. "This is to combat dehydration"

Donna smiled weakly as they led her back to the circle of mirrors.

"This is where we leave you" Rose said softly.

"I don't want to see that thing on my back" Donna said panicky.

"No! The mirrors are just incidental. They bounce chronon energy back into the centre which we control and decide the destination" Rose babbled quickly, trying to reassure her friend.

"It's a time machine like the TARDIS" Donna whispered awed.

Rose smiled sadly. "It's exactly like the TARDIS, once this is used the TARDIS will die. This is our last chance, last hope"

"If you could?" Mickey snapped interrupting Donna before she could ask anything else. Donna glared at him before walking back into the centre. "Powering up" Mickey shouted, the lights turned on.

"Didn't you once say that you might be possibly linked to the TARDIS?" Donna asked Rose, eyeing her blonde friend suspiciously.

"Hmm? Oh... yeah... I, I don't know. I was just... I was just guessing" Rose said trying to hide her guilty look. "Just remember, when you get to the junction, change the car's direction by one minute past ten"

"How do I do that?" Donna asked allowing herself to get distracted.

"It's up to you" Mickey replied with a cheeky grin.

"Well, I just have to... run up to myself and... have a good argument" Donna said thoughtfully.

Rose laughed. "I'd like to see that!"

"Activate loadstone" Mickey shouted while trying to smother a laugh. "Good luck" he said to Donna.

"I'm ready!" Donna said cheerfully.

"One minute past ten" Rose reminded her.

"Cos I understand, now." Donna continued as if Rose never spoken, she stared at Mickey firmly. "You said I was gonna die, but you mean this whole world, it's gonna blink out of existence. But that's not dying. Because a better world takes its place. The Doctor's world. And I'm still alive! That's right, isn't it? I don't die? If I change things, I don't die? That's... that's right, isn't it?" she looked to Rose for reassurance but the sad look on her friend's face told her she was wrong.

"I'm sorry" Rose whispered.

"But I can't die! I've got a future! With the Doctor - he told me!" Donna shouted.

"Activate!" Mickey shouted.

Sparks flew and Donna was suddenly engulfed in white light before disappearing. Mickey turned in time to see the dim light in the TARDIS fade and Rose collapsing. Mickey ran to Rose's side and checked her pulse, nothing. Their theories of her being linked to the TARDIS were correct. The TARDIS was dead and so was Rose. Mickey leaned over and pressed a kiss on Rose's lips.

"I'll make sure that this is fixed" he promised before standing upright and pulling out the dimension cannon, he pressed down on the button and disappeared in the blue flash.

He found himself on a busy road, people have stopped their cars to see what caused the lorry to stop and were about to get out of said cars. He made his way over to the prone body that laid on the road and bent down. He reached out and stroked the red hair.

"I'm sorry" he whispered. "But when you see the Doctor, I need you to give him this message" he then bent down to whisper it in her ear.

He was flipping through a magazine when the pair marched in looking furious, he tried to ignore it by giving them a grin. "Hey Boss what are you doing next?" he asked, the Doctor ignored him and began to flip the switches, slamming hard on the buttons and using the hammer on the console. "Charming" Mickey muttered.

"I'm...I'm going home Mickey" Rose said quietly.

"What? Why?" Mickey asked he was shocked, he thought Rose would stay with the Doctor forever. He looked over at the Doctor and shook his head if the idiot wasn't going to fight for Rose then Mickey will just look after her till he does. "You know what? Never mind I'll pack my stuff and we'll get going yeah?"

"NO!" Rose shouted. "I mean, no Mickey, you love this. You deserve to see more of it, explore your potential. I just need time on my own..." she then suddenly leaned in and he caught a whiff of her perfume. "If you ever need me, if something big happens and the Doctor is...just say Bad Wolf, Bad Wolf and everything will be all right" he nodded and pulled her into a tight hug.

He watched Donna exhale her last breath and stood up. Slowly walking away back to Pete's World.

He only hoped Rose was right about the Bad Wolf thing.
