The Doctor watched his reflection in the glass. That was the only thing he could really do in here. (He'd been in there for twenty-seven hours, three minutes, and two seconds).

"Geez, this is boring. What to do. . . " He tapped his chin thoughtfully. He sighed, plopping onto his backside. He laid on his back and closed his eyes. He wasn't sleeping; Time Lords rarely slept. When they did, it was after regeneration, or after a serious injury or exhausting task.

So the Doctor did the only thing he could think of. He contacted the TARDIS. Her presence was only faint. But if there was one thing the Doctor could do, it was talk to his beloved time ship. So he laid there, eyes closed, mind working on overdrive.

Buzzing echoed in his brain. He sent her a picture of where he was at. A dozen or so images flashed through his mind. A laboratory, fire, someone laughing, Bruce, and Tony. The Doctor smiled. She was making fun of them for trying to get inside her. He replied with an image of the key. She sent him a picture of it laying somewhere underneath the grating of the console room.

"That's where it was the whole time? Uh. I really need to be more careful," the Time Lord grumbled to himself. A mental image of the Doctor slapping himself in the face was sent to the TARDIS, who in turn hummed into his thoughts warmly.

"Whoa, that was weird," Tony said, startled, as he placed his hands out for balance.

"What?" Banner asked.

"I got some odd sensation. It felt like, I don't know, waves of energy." He glanced at his arm. He had goosebumps.

"Huh." The scientist shrugged. Suddenly, he shivered. "What the hell?" He looked at Tony.

"See! You and I both felt it now." Stark rubbed his arms. "It's not even cold in here."

"What do you think is causing it?"

A small humming met their ears. They immediately turned to the blue box sitting peacefully in the corner of the room.

"What's it doing?" Stark asked, cocking an eyebrow. Bruce shrugged in reply.

"Beats me."

"It's just sitting there, vibrating. Feels slightly cold around it." Tony stuck out his hand and touched the side of the wood. There was a hitch in the humming and suddenly the man was thrown backwards. Bruce reached for him and caught him by the arm before he could fall onto the floor.

"What in the hell?" Stark gaped.

"Seems like she's sick of you calling her an it," Banner joked. Giving the scientist a deadpan glare, Tony stood up straight and approached the box once again.

"You think it- she, can hear me?" he asked, not looking back as he tiptoed forward.

"I think so. She seemed to react to the Doctor earlier. She can feel and hear you. I'm guessing." Bruce crossed his arms.

"I'm gonna touch her again." He tapped the side of the wood cautiously. A light humming filled the air, but it sounded different.

Banner smirked. "I think she's laughing at you."

"A box can't laugh!" The humming turned into full out rumbling. Both the men put their hands over their ears to drown out the growls.

"She's offended! Great job, Stark," Bruce muttered sarcastically, rolling his eyes.

"But why's she all upset now? She was barely reacting earlier. The occasional hum," Tony retorted.

"She's sick of it, I'm sure. She doesn't want us in without permission." Bruce smirked slightly. "You better apologize."

Stark gasped. "I'm not saying sorry to a box!"

A sharp wind pushed the man back suddenly, making him fall onto his backside.

"Better do it, Tony~" Banner joked lightly. He was grinning at this point.

Stark stood up, a defiant look on his face. He raised his middle finger at the scientist behind them- who was currently trying not to laugh, stifling the escaping ones with his hand- and faced the box.

"Look, TARDIS, I'm soorrry," Tony groaned, rolling his eyes as he said it. The loud humming died down to a reasonable level.

"I still have that odd feeling though," Banner mentioned, looking at his arms.

"Yeah, me too. She's not too angry now, I hope," Stark moaned.

"It might not be the box."

"Then what else could it be?"

". . . . Good point."

"Should we possibly check on the Doctor?"

"Probably."

Without another thought, the two raced down the halls.
