All was quiet, except for the distant sound of the engines hissing and rumbling. Rory Pond lay awake, staring at the elaborate architecture of the TARDIS' ceiling. He couldn't sleep, because he couldn't stop worrying about The Doctor. He wasn't sure how long it had been, because time passes in such a different way when you travel in the TARDIS, but for a while now The Doctor had been acting odd. Well, odd for The Doctor anyway. Whilst they had visited other planets and had a lot of fun, The Doctor seemed more withdrawn than usual. So unusually quiet, it was lethargic. The Doctor was perfectly happy to leave Rory and Amy to their own devices, while he stayed back to tinker with his ship. It was getting more and more suspicious. Rory had to know what was wrong, before he could get any rest.
Leaning over the edge of his bunk, he looked down at his wife. She was turned towards the wall, still in her clothes and huddled into a fetal position. But was she asleep? He felt bad about disturbing her, but he really had to talk to her.
"Amy." He said in a hushed voice. Amy turned over, her eyes clearly wide awake. "You can't sleep either then?" Rory asked her. Amy nodded.
"I'm worried about The Doctor." She stated. Rory looked to her sympathetically and gingerly climbed down the ladder in the near-darkness to join his wife. He just squeezed on the edge of her bunk and placed an arm around her, pulling her tight to his shoulder.
"Do you think there's something he's not telling us, Amy?"
She considered this for a moment, then said "Well, it wouldn't be the first time." And Rory couldn't help but agree. The Doctor didn't share much of proper significance with them, even though he'd usually never shut up.
After a while of silence Rory turned Amy towards him in his arms and said "I'm going to go speak with him. Find out what's up." Pulling himself up from the lower bunk, he donned his orange dressing gown, over his green checked pyjamas. Amy hopped out of bed and followed right behind her husband.
Hand in hand, the Ponds entered the brightly-lit console room, unsurprised to see The Doctor tinkering with the controls and gazing at his scanner. Rory thought he looked pale, as the thin Time Lord leaned his head against the scanner and closed his eyes for a few seconds, before turning his gaze up at the sound of his companions' footsteps.
"Ah, Ponds!" he announced, before asking "What are you doing up?"
"We couldn't sleep" replied Rory.
"Hmm, I hear that can be a problem. I suggest counting sheep, or better yet, cocoa, a nice mug of steaming-hot cocoa. Yes that's it. Come along Ponds." And with that he led them both to the TARDIS' kitchen.
