Inside the medi-bay a bed had already been set up for the Doctor. The blankets had been turned down with an extra pillow. There was a clean medical gown folded on the bed. The Doctor didn't argue as he walked over to the bed, loosening his tie in the process. He was worried about the continuing seizures as well and hoped that all the test that Martha planned to run would provide him with an answer. He sat down on the edge of the bed taking his converse off and handing them to Jack. He stripped down to his pants putting the gown on before laying down. Osiris jumped up on the bed next to him and the Doctor stroked his back seeking comfort in his pet. Martha entered the medi-bay taking in the Doctor petting Osiris with Jack sitting on the bed beside him.

"First things first, I normally don't allow pets inside my hospital so Osiris will need to stay in the medi-bay with you or on the TARDIS at all times," Martha told him. He nodded, that one was easy as Osiris didn't tend to leave his side except when he went into Jack's room in Torchwood. Then he stayed at the top of the ladder waiting for the Doctor's return unless he was able to get Jack to take him down.

"Alright," The Doctor agreed.

"Next, I am going to be running a series of test including the MRI and CT scan to try to determine why you keep having seizures," Martha informed him. While Jack had failed to mention Osiris, he had let her know about the seizure the Doctor had the day before. "I am also going to keep you overnight in the medi-bay so that I can place electrodes on your head and monitor your brainwave activity while you sleep. Do you have any questions or concerns for me before we get started?"

"What kind of test?" The Doctor questioned

"The standard blood, urine and in your case energy levels. I am going to give you a top to bottom examination and if the MRI and CT scan come back clear I would also like to perform a lumbar puncture to check for infection," Martha explained. The Doctor winced but nodded as he did so. "Any other questions?"

"No," The Doctor replied.

"Then let's get started. Jack, I need you and Osiris off of the bed for awhile," Martha commented. Jack stood up and got Osiris down. The dog allowed Jack to lead him out of the room, where he placed him in one of the many gardens the Doctor had to allow him to stretch his legs. Returning to the Doctor's side, he offered him support while Martha ran through his vitals, drew blood, and then had him pee in a cup. She then wheeled him into a side room on the TARDIS where he received an MRI, CT scan, and she X-rayed his spine looking for any abnormalities. He was cranky from being isolated when he came out but a cuddle with Jack and a cup of tea made up for it. Though, it did nothing to alleviate his worry over the next procedure. He visibly paled when Martha came into the medi-bay about an hour later wheeling a cart with her.

He held onto Jack's hand not letting him go very far as he turned onto his side exposing his back for her. With Martha's guidance, he curled slightly into himself. Finding the right spot, she then cleaned his back with iodine before then warned him before picking up the first needle. The Doctor gripped Jack's hand tightly in his while he held onto to the blankets with the other hand. Jack gently stroked the Doctor's head comforting him as his grip tightened even further and he sucked in his breath with a hiss.

"That was the worse part over, Doctor. Just keep breathing," Martha told him as she finished numbing the spot on his back.

"I am breathing you stupid ape," The Doctor hissed crankily.

"I wouldn't insult the person who is about to put a needle into your spine," Jack reminded him. He just rolled his eyes at Jack not apologizing. While he was happy to be back on his beloved TARDIS and feeling her also comfort him by humming softly to him, he was miserable in the medi-bay. He just wanted to go to the kitchen get a fresh cup of tea and then read in the library for a few hours. Yet, here he was laying on his side with a needle sticking out of his back. Yes, he agreed with Martha that he needed the test but that wasn't the point. He felt Jack's hand move to thumb away one of the tears that escaped and he offered him a weak smile.

"After you have rested and had another cup of tea, we can go for a walk around your garden with Osiris before you have to lay down again for the night. How does that sound?" Jack questioned him.

"If I'm allowed to move," The Doctor sighed. Martha tutted at him. Removing the needle she placed pressure on the spot for a moment before having him roll onto his back. He lay there obviously pouting while she cleaned up and Jack tried to comfort him. Leaving the room for a few minutes, she quickly returned with a cup of tea and a bouncy furry creature who was happy to see him. At least that got an actual smile as the Doctor accepted the tea from her. Returning to the lab, Martha once more began her test to try to determine what was causing his seizures.

"I'm sorry, Jack," The Doctor apologized as soon as Martha was out of the room.

"What for?" Jack questioned in confusion.

"Putting you through this. You deserve better than a drug addict for a lover. You should be with me traveling the universe, not sitting by my side while Martha pokes and prods me," The Doctor pouted feeling sorry for himself.

"I love you Doctor and want to be here by your side. Regardless of whether we are traveling together or not, it doesn't matter to me. I have spent over two-thousand years waiting for you and I am just as happy here with you as I would be among the stars as long as we are together," Jack reassured him kissing him softly on the head. While he would love to see the stars again and be out among them, he meant what he said. If he had to live the next million years on earth, as long as he was with his lover he would be happy.

"And if she can't find a reason for my seizures?" The Doctor questioned him seriously.

"Even if we can't travel as much, we can build a life here on Earth together. I know you always told Rose that you don't do domestic, but would living in a house in Cardiff with me really be that bad?" Jack wondered and the Doctor shrugged. Jack kissed him on the side of the head before continuing. "If you can't settle down, then we can still run together and I will be there to catch you when you fall."

"Promise?" The Doctor questioned.

"Always," Jack answered cuddling him closer. The Doctor cuddled into Jack laying as close to him as possible while still remaining on his back. He chuckled as Osiris pushed in between them with his nose seeking the attention of his owner. The Doctor reached down scratching his ears, cooing at his pet.

"Should I come back later?" A voice asked from the doorway. The Doctor sat up quickly wincing in the process as pain shot through his back. That didn't matter, though, as he stared at the older man standing in his TARDIS.

"Wilfred," he said happily.
