"Argh! Stop it!" the Doctor heard a man screaming from up ahead. He and McDonnell were running through the corridors of the ship. McDonnell was sprinting at full speed, not even caring to see if the Doctor was following her. The Doctor didn't even think she knew that he was running after her.

"Korwin! It's Abi!" another voice yelled. "Open your eyes! I need to take a look at you!"

"Korwin!" McDonnell cried as she and the Doctor entered the med-centre. "What's happened? Is he okay?"

The Doctor pushed past her to stand beside the struggling man on the medical slab. Korwin continued yelling, fighting against the man and woman holding him down.

"Oh God! Help me!" he shouted. "It's burning me!"

"How long's he been like this?" the Doctor asked, helping to hold Korwin down.

"Ashton just brought him in," the woman called Abi grunted pushing Korwin down on the board. The Doctor pulled his sonic screwdriver from his pocket and began scanning the man.

"What are you doing?" McDonnell choked out.

"Don't get too close," the Doctor grunted as the sonic whirred.

"Don't be so stupid!" she pushed past Ashton to stand closer to Korwin. "He's my husband!"

"And he's just sabotaged our ship!" Ashton snapped forcing Korwin back down.

"What?" McDonnell whipped her head around to face him.

"He went mad," Ashton said. "He put the ship onto secure closure, then he set the heat pulse to melt the controls."

"No way," McDonnell argued. "He wouldn't do that!"

"I saw it happen, Captain."

"Korwin?" the Doctor spoke up. "Korwin, open your eyes for me a second."

"I can't!" Korwin shook his head keeping his eyes firmly closed.

"Yeah, 'course you can," the Doctor said. "Go on."

"Don't make me look at you!" Korwin cried. "Please!"

"Alright, alright! Just relax," the Doctor looked around to the medical table behind him and grabbed an injection gun. "Sedative?"

"Yes," Abi nodded. Korwin gave a final yell as the Doctor sedated him. His body went limb and the four crew members released their hold on him. The Doctor placed the sedative back on the table and crossed his arms, staring intently at Korwin.

"What's wrong with him?" McDonnell looked to the Doctor.

"Rising body temperature, unusual energy readings," the Doctor sniffed. "Stasis chamber! I do love a good stasis chamber."

The Doctor pointed the machine behind Korwin.

"Keep him sedated in there," he nodded. "Regulate the body temperature."

Abi turned away and began tapping out commands for the machine.

"And, just for fun," the Doctor furrowed his brow at Korwin. "Run a bioscan and tissue profile on a metabolic detail."

"Just doing them now," Abi turned her head to look the Doctor up and down.

"Oh, you're good," the Doctor raised his brows. "Anyone else presenting these symptoms?"

"Not so far," Abi frowned at him.

"Well, that's something."

"Will someone tell me what is the matter with him?" McDonnell's voice broke.

"Some sort of infection. We'll know more after the test results," the Doctor turned to face her. "Now, allons-y! Back down stairs! Eh? See about those engines. Go."

Ashton nodded and left the room, casting a glance at the Captain as he did. McDonnell ignored the Doctor and continued to look down at her husband, gently caressing his face.

"Hey," the Doctor said loudly and McDonnell looked at him. "Go."

With one last glance at Korwin, McDonnell turned and followed Ashton out the room. The Doctor turned to Abi.

"Call us if there's news," he called as he made his way to the metal door. "Any questions?"

"Uh, yeah," Abi's voice stopped him. "Who are you?"

"I'm the Doctor!" he stated leaning in the doorway briefly. And with that, he ducked out and ran down the corridor, leaving a very confused Abi alone. The woman gave her head a shake and went over to screens monitoring the stasis chamber. But unbeknownst to her, Korwin was starting to stir.

-DW-

A few minutes after they had reached the engine room, the Doctor ran up to the intercom and pressed the button connecting to the med-centre.

"Abi, how's Korwin doing?" he asked. "Any results from the bioscan?"

"He's under heavy sedation," Abi's voice came through. "I'm just trying to make sense of this data. Give me a couple of minutes and I'll let you know."

In the stasis chamber, Korwin's hand fell from his chest and onto the slab, twitching slightly as his body began to wake.
