Author: I couldn't remember if Jack still had the key or part of a key. I wasn't really into the episodes with the Master. So for the purpose of this tiny scene, he still has it.

"Don't be a stranger Doctor," Jack's muffled voice said over the Doctor's shoulder.

"We won't," he replied releasing him from the vice like hug.

"And..." Jack put the rusty chain keeping the old Tardis key around the Doctor's neck, "No more misunderstandings," he winked, "It's not like I need to be invisible anymore"

He gave them one last big grin, "Good luck you two. No little Time Lords running around Doctor!"

"No no!" the Doctor called, "Where could I possibly keep them?" He felt River's fingers slide between his.

"Come on sweetie"

He put his mouth to her ear quickly, "All of time and space," he whispered, "Next stop. Everywhere" With the biggest, most childish grin he could wear he leapt to the console platform.

"Now... Doctor River Song... where shall we start? One condition... it has to be amazing! Get that book out! Let's start ticking the checklist! HaHaa!" he pulled the final lever and the Tardis sprung into action. It rocked and shook; River struggled to stay standing as she watched the Doctor, her Doctor piloting his favourite companion. With a final uncertain tumble the Tardis came to an abrupt halt. River found herself stumbling, "Not that way," the Doctor smiled catching her around the waist.

"Doctor... once you know who I am ... everything changes between us"

"A good change or...?"

"Spoilers..."

He looked thoughtfully at her, "No you're right... spoilers" he took a step back pulling out his sonic screwdriver, "Let's see what we've got here then" The Doctor strode past her, River closed her eyes raising a hand to her head. After a few deep breaths she followed him. She exited the Tardis deep in thought and walked straight into his back.

"Sshh," he instructed with a whisper, he put an arm behind himself as if to protect her as he moved his screwdriver slowly around in front of him.

"What's wrong?" River whispered.

"It's too quiet..."

River's brow furrowed as she checked her PDA, "Sweetie... do you even know where we are?"

"Of course I do ... we're at Trithon ... we're..."

"... not at Trithon..." she cut in tapping away in her casual manner.

"Well... where are we then?"

"Asgard," River smiled looking up.

"... Oh... Asgard..." He looked around biting his lip.

"The ultimate couples retreat..." River continued, "Oh Doctor... you spoil me"

"I didn't ... Why has the Tardis brought us here...?" He ran back inside, leapt up to the console and began tapping away, "I knew it... I didn't set it for Asgard..." He continued tapping looking vaguely confused.

"Well we're here so ... let's make the most of it... I doubt you'd bring me here again of your own accord," River sighed as she settled herself on the sofa. The Doctor frowned and glanced at her before continuing around the controls.

"The Tardis brought us here for a reason..."

"Doctor you made a miscalculation... there doesn't need to be a reason for everything!"

"Everything happens for a reason"

River shook her head, "Well I'm going to enjoy myself while I'm here" She rose and wandered into another area of the Tardis. The Doctor, ignoring the crashes and bangs coming from her direction, continued examining the screen and pulling every lever and switch within reach.

"Why... why would you bring me here?" he asked resting his head on the edge of the console in defeat. He didn't notice River march past with a Tardis blue blanket under her arm. Presumably after setting it outside she marched back past him to gather more items. The Doctor raised his head, "I suppose I could do with a small break..." he decided finally, "yeah... we'll be having words later though," he warned the console waggling his finger at it. River once more began to march past him; in her hand she held a bottle of strange red looking soda.

"Oooh I didn't know they still made that... excellent... where's mine?" the Doctor exclaimed.

"I didn't think you were coming..." she frowned.

"Of course I'm coming," he replied shaking his head. He took off into the refrigerated section of the Tardis to begin his search for the soda. After a lot of crashes, bangs and crunches River came to his rescue,

"Doctor!" she called from the doorway waving two bottles in her hands.

"Excellent..." he stammered rubbing his cold hands together as he followed her across the console room.

Door open, River stepped out into the sunlight,

"Now..." he said straightening his bow tie and jacket, "environment check"

He put his finger in his mouth then held it out high in front of him before stepping outside himself.
