A/N: Well, here we are - the last chapter! I hope you've enjoyed our little journey with Clara around the TARDIS.

She didn't stop until she reached the swimming pool, where she jumped in, fully clothed, and lay there floating for a while.

Chapter 4

After getting dried and changed, Clara walked into the console room to find the Doctor sat on a stair, tinkering with a strange looking silver object which was presumably part of the TARDIS. She went over and sat down next to him, resting her head on his upper arm.

"Doctor, I think you need a hug," Clara said softly.

"Do I? Oh, I hadn't noticed," the Doctor said, the hint of smile on his lips.

"Yes, you do. After all you've lost I think you deserve at least that much."

He smiled. "Alright then." They wrapped their arms around each other and cuddled for a few minutes, listening to the calm humming of the TARDIS. The time passed slowly and Clara let the faces of the companions she'd seen float through her mind. Is that all she'd be one day? A memory of the Doctor's? Because that was all that those people were. A brilliant, happy memory with a sad ending. A silent tear slide down Clara's cheek. He'd lost so many people. He'd had so much pain.

When the Doctor pulled out of their embrace, he took one of Clara's hand in his two palms, clearly having noticed her upset. "Where did you go earlier?" he said, his voice gentle and comforting.

"I..." she said, wondering what to say. Was it wrong that she'd been looking around rooms that didn't belong to her? She would just have to tell him. It wouldn't be right to lie. "I went down this one darker corridor with purple walls and as I walking down it, a door opened just as I went by. I went inside and found a bedroom. The same thing happened as I went down the corridor, more and more rooms opened up. I know about Amy and Rory and Donna and...and Rose."

The Doctor's face fell, and he closed his eyes, as if holding back tears.

"I'm sorry, I didn't think, I shouldn't have been in there," she said, feeling ashamed.

"No, no, don't be sorry, the doors opened for you. That corridor is usually very hidden, I think the TARDIS moved it closer to where you were because she wanted you to find out about them."

A moment of silence passed, before Clara spoke again. "There were more, weren't there, Doctor? I didn't look in most of the rooms, I just couldn't."

He took a deep breath. "Yes. There were so many others. Ian, Peri, Ace, Susan, Adric, Romana, Sarah Jane, just to name a few. They all meant so much to me, and always will. You mean a lot to me too, Clara. Don't you go forgetting that," he said.

Clara leant in and gave him another cuddle. They smiled at each other.

"My impossible girl."
