The three companions ran to the control room, the Doctor in the lead. Automatically he rushed to the screen showing the outside of the TARDIS. Rose followed and gasped as the TARDIS gave another violent shudder.

"Is that…?"

The Doctor nodded. "Yep."

Rose looked up to the Doctor's grim gaze. "But—"

Jack glanced at the screen. "Whoa!" he exclaimed. "Are we in the inside of a dinosaur's mouth?"

The TARDIS rocked again and Rose flew forwards into the Doctor's arms. As he helped her steady herself, the Doctor gave Jack an exasperated look.

"Yes Jack. A dinosaur is trying to eat us."

Jack opened his mouth to comment, saw the Doctor's warning expression, and shut it. The Doctor smiled forcefully.

"Now. You two, grab onto something and mind your heads. This might hurt a bit," he said as he pulled out his sonic screwdriver and ran to the door.

Fighting to keep his balance, the Doctor opened the door to be greeted by several large and rotten teeth. Wrinkling his nose at the smell, he poked his head out and looked up to the roof of the dinosaur's mouth. Biting hard on his lower lip, he aimed the sonic screwdriver at the fleshy ceiling and turned it on. A light blue laser shot up and through the dinosaur's mouth with just enough electricity to hurt. The dinosaur roared and dropped the TARDIS, making it bounce quite a ways away. The Doctor hit the floor hard and rolled, as Jack and Rose flew on top of each other. As soon as they came to a stop, Jack hauled himself up and helped Rose, who was wincing and rubbing the back of her head.

"Yep. That hurt."

The Doctor ran to the still-open door to see the enraged dino storming towards them. He grinned, and then turned back inside.

"Jack, distract the dino, I'll try to move the TARDIS."

Jack nodded, pulled out a banana from his coat and ran outside.

"Hey you! Like bananas?"

The Doctor smiled, then rushed to the main console, working furiously.

"Rose, close the doors!"

"But Jack—"

"The TARDIS can't move with the door wide open! We don't even know if it'll work and if it does, we'll come back for Jack!" the Doctor interrupted, not looking up once. Rose hesitated briefly, but then did as the Doctor bid.

"Right," the Doctor said as soon as he heard the door latch shut. "Now c'mere and watch that screen right there."

Rose rushed to the screen he had indicated to see Jack…and the dinosaur still running towards them.

"Tell me when the dinosaur's only a few meters away," he ordered. Rose nodded, though she knew the Doctor didn't see it.

Suddenly the image on the screen changed and the Doctor looked up.

"Did we move? I think we moved…. Did we move?" he asked, looking over Rose's shoulder.

"Yeah, we moved. We're behind it now," Rose replied. The Doctor grinned.

"Fantastic. Right now. Jack."

The two friends ran to the door and opened it. The Doctor caught Jack's eye and gestured for him to run to the TARDIS. Jack gave the large beast charging at him one last glance before abandoning the banana and running at top speed to the open TARDIS.

"Well, c'mon then. We can't stay here all day," the Doctor urged as soon as Jack got close enough. He ushered Jack into the TARDIS, closed the door, and ran back to the controls.

"He's comin' back," Rose informed him as she went back to her post.

"How d'ya know it's a 'he'?" Jack asked coming up behind her. Rose looked at him with a raised eyebrow.

"Does it really matter?"

"No, it doesn't," the Doctor answered, "so you two stop arguing and gimme a hand. Jack, you see that big green button over there? Hold it down. Rose, you keep an eye on that dinosaur."

Jack and Rose did as they were bid and the Doctor worked quickly, muttering to the TARDIS under his breath.

"C'mon girl. C'mon. Don't think you wanna be eaten either. At least get us somewhere sheltered…"

After a moment, the Doctor looked up, his eyes immediately on Rose.

"Rose?" he asked.

"We're in some kinda forest…" she replied. The Doctor grinned and went to look for himself.

"And it seems dense enough…fantastic," he declared. "We should be safe here for now."

Jack nodded, satisfied, and walked out the room. Rose and the Doctor locked eyes for a moment.

"So…what now?" Rose asked after awhile. The Doctor shrugged.

"I'll try to figure out what's wrong with her," he answered, patting the console. "And then I'll try to fix whatever it is."

Rose nodded, standing there awkwardly.

"Well…I'm gonna go to the gym," she told him. Then she walked away, leaving the Doctor racking his brain, trying to figure out what could possibly be wrong with her.
