Jens watched the rise and fall of the sleeping man's chest, and then checked the monitors. All gauges were at healthy levels. Mara requested that restraints be used so that intravenous solutions could slowly flow into him to restore balance to his body and brain tissues. The team had agreed to take turns at Gray's bedside until he came to consciousness. Even though he was exhausted, Jack made them all promise that he would be wakened as soon as there was any sign. Jens was equally insistent that Jack not be alone with his brother. He understood the Captain's need to find a way to heal his homicidal sibling, but Jens wasn't ready to risk Jack's safety either.

He turned as he heard Gray murmur and shift his body. Jens triggered a message to the sleeping crew, and then waited. Gray's eyes blinked open, and began to focus on his surroundings. He frowned as he surveyed the infirmary. He tried to sit up but fell back; his muscles were too weak due to prolonged inactivity. He focused on Jens.

"Who are you?" he demanded. "Where am I?"

"You are aboard our TARDIS," replied Jens firmly. "You are our guest."

"Prisoner, more like. Where's Jack?" Gray was agitated. "Where's my brother?"

Jack and Mara arrived at the same time. Jack circled over next to his partner, while Mara checked the monitors and picked up her patient's wrist to take his pulse. Gray snatched his arm away.

"I'm not going to harm you," she said. "I'm a doctor."

Gray looked suspiciously from one face to another, and finally allowed her to continue. He turned and looked at his brother.

Jack moved closer. "How are you feeling?"

Gray turned his head away and was silent.

Jack looked anxiously at Mara.

"I need some time with my patient," she said. "Alone."

Jens and the Captain reluctantly left the room.

The Catkin doctor settled in a chair next to the bed, and waited for Gray to make the first move. He continued to stare at the opposite wall.

Finally, he spoke. "So what do you plan to do with me?"

"Do with you?" Mara was incredulous. "I'm a doctor, I plan to help you get well."

Gray snorted. "No, you're his doctor. I just murdered two of his friends, and destroyed half his city."

"That was four hundred years ago."

Gray turned in surprise and stared at her. "What?"

"You murdered them four hundred years ago," she repeated. "Your brother kept you alive hoping to find a cure."

Gray took a deep breath. "A cure for what?"

"Trauma. Jack told me your story. I believe you are suffering from psychological trauma from your years in captivity, a type of post traumatic stress disorder causing temporary insanity."

Gray shifted uncomfortably.

"We have therapies for that now." Mara came closer. "Would you allow me to examine your neck?"

Gray eyed her suspiciously, but allowed her to pull back his shirt. The geometric scar was carved into his neck and part of his cheek. She ran her fingers over it lightly, observing the structure.

"Can you tell me about this?"

Gray settled back into the pillow and closed his eyes. Mara waited. Finally, he whispered, "These creatures, the most horrible…" He could not continue.

"I know something about the creatures that make this mark," she said softly. "They are part of our time too. I'm going to ask you a few questions. Just nod or say 'yes' if I am right. "

Gray kept his eyes closed and nodded.

"You were just a boy when you were taken," she said. "Usually they kill their victims, but sometimes take a child as a type of pet forcing him to watch what they do. Did this happen to you?"

Gray winced. "Yes."

"Did one hold you down as you became more frightened?" Mara asked. "These marks on your neck...did they sampled your blood? "

Gray's body tensed. "Yes."

Mara carefully took his hand and held it as she continued. "Did they cause more fear by distorting your memory or planting new images?"

His grip tightened as he nodded. His breaths were increasing and shallow.

"As you grew older, did they force you to participate in exchange for your safety?"

"No!" Gray exploded and pulled away from her. "It's not like that. I didn't. They made me clean up, but I couldn't…I wouldn't…" His face twisted with anguish. "Stop! I don't want to remember!"

Mara quickly looked at the monitors and adjusted the medication to calm him. She stayed silent as his breathing began to slow to normal.

"I want you to hear me, Gray." Mara came closer and took his hand again. "What happened to you was not your fault. You were manipulated you for their pleasure... A child destroyed for their pleasure." Gray's eyes met hers. "If you stay like this, they win."

Gray closed his eyes, trying to block the memory.

"There is a way back," Mara continued as she squeezed his hand. "If you trust me, trust us, we can help you find a way back."

Gray turned away. "Why would you care? Why would anyone?" He whispered hoarsely, "I'm a monster."

"Jack cares," she said quietly.

Gray said nothing.

"He forgave you," she said softly. "And he searched for a cure for centuries."

Silence. She waited, but he would not turn back to her.

Finally, she said, "I want you to think about that. Give Jack a chance. Give yourself a chance." She adjusted the quilting around his body and again checked the monitors. He became drowsy as sedative took effect.

She felt his forehead for fever, and then lightly brushed his hair back from his brow. "Rest son, we'll talk in the morning." The doctor settled back in her chair, and waited.

After she was sure he was asleep, she quietly left the room and closed the door. She found the Captain pacing. He stopped, and anxiously turned towards her. Jens stood behind him, arms folded against his chest.

"How is he?" Jack asked anxiously. "Is he coherent?"

"He's adjusting," she said cautiously. "He's…damaged, Jack. My scans show the scars of trauma but not insanity. I think that the new treatments involving rebalancing the body chemistry and talk therapy will give him a chance at a normal life." She took Jack's hand. "He needs time. He needs to learn to trust again, trust me, and especially…trust you."

Jack stepped back, pushed his hands into his pockets, and stared at the floor.

Jens moved forward. "That's well and good, but I want to take precautions."

Jack turned towards his partner in surprise.

"What kind of precautions?" Mara asked.

"As soon as he is well enough to leave the infirmary, I want him confined to his quarters or at least closely monitored. Anything that could be turned into a weapon should be secured, anything sharp or can be made into a weapon."

"This isn't a prison!" protested Mara. "He needs to be able to feel he is trusted. He needs to see Jack as his brother, not jailer."

"Trust needs to be earned," Jens said firmly.

"It's my fault he is the way he is," Jack said softly. "I need to help him find a way back." He looked up at Jens.

"Then at least have another person in the room with you, Jack!" Jen insisted. "He tried to kill you!"

"I understand your concern, but I need to do everything in my power to give him back a life," Jack pleaded. "He's my brother!"

Jens stood silently for a time and then addressed Mara. "What do you need?"

"I have him on intravenous fluids to rebalance the cortisol and serotonin levels that were disturbed in the blood. We could then transfer him to his room. The treatment can be continued using shots, then pills. After awhile, just monitoring will be needed." Mara looked towards Jack. "What is important is to get him into a normal pattern of trust. He needs the company of family and friends. Then he can slowly merge into the outside world of strangers and work. We could do that while you two can continue your work with the Conservancy."

"I still want anything that can be used as a weapon secured," Jens said firmly. "We can do everything else, but I want that. And he needs to be monitored. Agreed?"

Jack and Mara nodded in agreement.

"I guess I'd better get a room ready," said Jens as he turned to make his way to the sleeping quarters. He left the other two standing by the infirmary door.

"I'll take the next watch," Jack offered.

"He should sleep through the night," Mara said. "I'll be back in the morning to check his levels and take him off the I.V."

Jack nodded absently as he watched Gray sleep.

Mara stopped. "Jack, are you alright?"

"Yeah, I'm fine," he said quietly. He opened the door to the infirmary and walked back in, quickly scanning the monitors. He quietly pulled up a chair next to his sleeping brother, and sat down. Gray's breathing was slow and regular.

Mara watched the two men from the door. One brother strapped to a hospital bed, and the other holding vigil; both locked in a prison of guilt and pain. She slowly closed the door and returned to her room.
