Author's Note #4: Alright. So I've gone back and watched bits of "Brothers in Arms" again. That's the Highlander episode with the flashback that reveals how Joe lost his legs and learned about Immortals and the Waters. It's been a while since I last saw it, and I realize I've got some details wrong about Joe's time in Vietnam. I'll fix them in editing. In fact, as a fair warning, all of these chapters could be subjected to editing at any time, either light editing or heavy editing.

Author's Note #5: I am not a scientist. Looking for proper science? Send me a review or e-mail detailing what I got wrong, and I'll do my best to fix it.

Deeper into the Box

"Joe?"

Joe stopped laughing.

"What's going-" The Immortal's eyes widened. He rubbed his healed neck. A whole range of emotions flickered through his eyes, from surprise, fear, embarrassment, annoyance, regret and, at last, resignation. He sighed and sat up.

Joe slowly stood, using the floor-turned-wall for support. He stared at Adam and was about to say something, though he wasn't sure what, when Jones stepped between them. She helped Adam get to his feet and whispered something in his ear. Joe thought he heard her say his name and frowned at the back of her head.

"You all right, Adam?" the Doctor asked.

Adam glanced up. His eyes widened as he took in his surroundings. "What's happened to the TARDIS?"

"You're been here before?" Joe blurted.

Adam winced. "Ah…"

He couldn't believe this. "Any other secrets, Adam?"

Jones glanced from one man to the other with a worried expression.

A dozen emotions passed through Adam's eyes. "Joe-"

"All right!" the Doctor yelled. Joe's ears rang. "If everyone could lean against the floor…wall…um, the floor-that's-temporarily-become-a-wall, I can see about straightening us out. Come on, shift!"

Jones stayed between them as the three of men moved to the floor-that-had-temporarily-become-a-wall. Joe didn't want a mediator. He glared over her shoulders at Adam. "You know these people?"

"Excuse me!" The Doctor gave them a look worthy of a disapproving first grade teacher. "Backs against the wall!"

Joe made a face but did as instructed. Adam wouldn't meet his eyes.

Adam cracked his neck. Standing nearly shoulder-to-shoulder with him, Joe heard it easily.

"Make sure your back is firmly touching the floor…wall…thing," said the Doctor. The possible Immortal wrapped his arms around the glass column and reached almost completely around it for a lever. He pushed the lever, and his body slid to the left. His grip tightened on the column. Joe winced, not just in sympathy but also in the hope that the guy didn't drop straight on him.

With a sigh, Joe shifted his weight and leaned as heavily as he could on the floor that had become a wall when the room had fallen on its side. He was tired, his legs hurt, and he was not looking forward to this. "Just get on with it," he muttered.

"On the count of three!" the Doctor said.

Martha leaned forward and smiled at Joe from Adam's other side. "Don't worry. It'll be fine."

"One, two, four-"

Joe gave the oblivious man another look of disbelief. He was starting to feel permanently baffled around the Doctor.

The Doctor continued, "No, hold on-three!"

The room began to tilt again, but slowly, about the speed of a reclining bed. More and more of Joe's weight shifted to his back as the wall resumed its original purpose as a floor. He felt a little disoriented from the process.

With a slight lurch, the room seemed to lock into its proper place. Joe's feet rested on the blue wooden doors beneath the backward 'POLICE PUBLIC CALL BOX' ledger.

He went through the laborious process of standing up, again. Adam held out a hand. Joe glanced at it but took it. Adam gave him a sheepish smile that he chose to ignore.

"Are they gone?" Martha asked.

"No. The Vordren have us surrounded, though they're not doing much beyond sitting at the moment. The TARDIS is still on its side. I've just fixed the center of gravity in the interior."

"So." The Doctor rubbed his hands together. "An explanation!"
