Okay, so I decided to finish the next chapter last night, but Fanfiction wouldn't let me upload for some reason! Here it is now though, hope you like!

Please R&R, it makes me super-duper happy!

Disclaimer: Once again, I do not own Doctor Who. Much to my deep sadness.

The Doctor grabbed Amy's hand and pulled her towards the stairs before she could protest.

"If I am correct, the location of that life form was towards the north side of the TARDIS, so if we head down the main corridor just up here, we should be moving straight towards it. That's if the TARDIS doesn't decide to switch the room locations around, of course."

Amy groaned as her slipper-clad feet pounded up the stairs behind the Doctor.

"So that means we could be looking for days then?" She asked, exasperated.

"I doubt it." The Doctor answered cheerily. They were moving down the main TARDIS corridor now. The walls were steel grey and bare. Amy shivered as the memory of being chased down these very corridors by House came back to her, and she suddenly wished it was Rory's hand she was holding. As if he read her mind, the Doctor gave her hand a tight squeeze before falling into step beside her.

"Everything ok Pond?"

"Yeah, I'm fine, just a little cold, it's fine" She smiled weakly.

"Oh that's not a problem! We can just-" Before the Doctor was able to finish his sentence, the cold grey corridor suddenly took on a warm glow. "- turn on the heating … excellent!" He exclaimed happily, clapping his hands together. "Now then, onwards Pond!"

Amy smiled, this time in earnest. She could feel the heat beginning to warm her toes nicely.

"Thanks." She whispered quietly. She knew just as well as the Doctor did that the TARDIS could still hear her.

When they reached Amy and Rory's room, they were greeted with the strange whispering that had woken Amy.

Doctor … Doctor…

The Doctor stopped. "Is this what you heard Pond?"

"Yeah … but its fainter now, I can hardly hear it …" She frowned, attempting to listen.

"Yes." The Doctor replied. "Seems strangely familiar, but I don't know where I've heard it …"

Doctor…

"It's female. Definitely." Amy decided.

The Doctor merely nodded in agreement. They stood rooted to the spot for several more minutes, but the sound seemed to have stopped.

"This way, I believe!" The Doctor suddenly exclaimed, striding forwards again. "Come along, Pond!"

They moved quickly down the corridor, ignoring the smaller corridors which branched off in all directions. As they walked, they passed doors of all shapes and sizes – wood, metal, glass, and other strange looking materials Amy had never seen. Neither she nor Rory had ventured this far into the TARDIS before. The Doctor strode confidently beside her, pointing out the names of different rooms animatedly.

"Oh yes!" He exclaimed as they passed a door which appeared to be made of stone. "Now that is one of my favourites!" He grinned in that ever-so-slightly-insane manner of his.

"Why? "Amy asked, glancing back at the door. "What's in there?"

"My rock collection!" The Doctor replied fondly.

"Greaaaat." Amy muttered sarcastically.

"Hey, I will have you know it took me absolutely centuries to build up such a collection. River did help me to retrieve a few specimens, naturally, being an archaeologist and all. But the majority I obtained entirely on my own merit. There is a particularly sought after piece in there which -" The Doctor stopped dead in his tracks in front of a painted blue door. "oh."

"Oh?" Amy asked, glancing from the Doctor to the door and back again. The Doctor was still silent; merely staring at the door with a strange look on his face Amy couldn't quite place. "What's the matter?"

"That … that door. It's new." He answered slowly.

"Oh so the TARDIS decided to do a little redecorating without you, it's no biggie!" Amy said offhandedly.

"No, you don't understand. The doors never change. Maybe the rooms change position within the ship, but the actual doors are never changed. I have never seen this room before." The Doctor was suddenly very serious.

"Doctor, it's a big ship. Maybe you just haven't noticed this one before. Maybe it's just like a, um, storage room or something?" Amy offered.

The Doctor turned to face her. "Amy, I have lived and travelled in this ship for over 600 years. I know every room. . Room." He stressed the last three words particularly.

Amy swallowed audibly. "Oh-kaay, so now what? Do you think whatever that red dot was could be in there?"

The Doctor whipped his sonic screwdriver out from his jacket pocket. "There is a good possibility." He scanned the door and checked it.

"Do you think it might be like, dangerous or something?" Amy asked uneasily.

"Maybe. But the red colour of the dot means that it is weak. Really weak. There are two of us and one of it. We should be fine, whatever it is."

"Yeah great!" Amy said sarcastically. "Earth-girl in her nighty and slippers and 900 year old mad man" -she quickly corrected herself- "Alien thingy against the unknown. Excellent. Just brilliant." But she was cut short as the Doctor placed a finger to her lips and shushed her. He had his head against the door and was listening intently.

Doctor…

That voice. He knew it. He couldn't ever forget it. But how? It wasn't possible.

Doctor.

He jumped backwards in alarm, removing his finger from Amy's lips.

"Ah, er, right Pond. On second thoughts, maybe I should pop inside first. Alone. Just to er, you know, check. It could be dangerous. Or scary. Or big! Yes or big. Big, dangerous and scary. Yes. Best if you stay out here. Back in a tick!"

And with that, he disappeared behind the door. Amy stood, speechless, alone in the corridor. It took her a few seconds to actually come to terms with the fact that he had just abandoned her. But then she came to her senses, and slammed herself against the blue door. Which didn't budge.

"Doctor!" She yelled, yanking the door handle. "DOCTOR! I know you were lying! You know what's in that room! DOCTOR! YOU HAD BETTER LET ME IN RIGHT NOW!"

Phew! Second chapter fin. I hope you liked. What's behind the door? *gasps*. Sorry there hasn't been a great deal of major action yet, but I think the next chapter will more than satisfy ;)
