Author's Note: Thanks for all the amazing Reviews! Second chapter, I have no idea how many there will be, but we'll see where the muse takes me. As for more, I would like to rewrite this story at some point with Chris' doctor instead. So I think I'm going to use on of the challanges from Times and Chips and go with that, which will make the series much longer lol. Stay Tuned.

The Littlest Time Lord
Chapter Two: Sick

It deeply reminded Rose of the 1860s in America—the Wild West as she knew it. On the planet Dagan, it was supposed to be a pit stop of sorts. The doctor had a short meeting with the Prime, while Rose took her son and gathered food, clothes and other small trinkets as desired.

The abnormally docile blue eyes looked around as his mother dragged him along by the hand, through the hoards of humans and aliens alike. He was vaguely aware of his mother and father talking in hushed tones as they hurried toward whoever it was they were supposed to be meeting. "Mummy, I'm tired," whimpered the little boy.

Rose had noticed her son's unusually dragging feet, "I know sweetheart, just a bit further okay," Rose promised her only son half heartedly as she continued to listen to her husband describe the planet and what they were going to be discussing during their short meeting with the Prime of Dagan.

The small child sighed as he forced his short legs to go faster and keep up with his mother. "Doctor, stop," Rose finally noticed her son had begun to slow down. The tenth doctor glanced back at his wife. She reached down and lifted the four year old boy into her arms, pulling him close.

"Is he all right?" He questioned as he watched Jack lean his head against Rose's shoulder.

"Just tired, we can go," she whispered as she held him closer. Rose sighed in contentment, she was happier now than she'd ever planned on being, and she knew while the Doctor loved to complain from time to time, he adored this little boy, the light of his life.

Jackson Peter Tyler was the Littlest Time Lord, and among other things he was inhumanly smart. But above all else, he was their son. She knew deep down that the Doctor had never really intended on having children and carrying them around on his missions, but their binding, and the passion they had for one another had changed everything. Jack had changed everything; and he tried so hard to make his dad proud.

Rose watched as Little Jack imitated everything his father did, trying to be just like his father. And no matter how often the Doctor tired to deny it, he reveled in the attention. She'd caught him more times than not grinning as their son attempted to fix parts of the TARDIS with a little sonic screwdriver. Or as he tried to reach the leavers to help his daddy, control the time machine.

She smiled softly as she felt the small body leaning heavily against her's, his even breathing as he relaxed in her loving arms. She turned and pressed a kiss to his forehead, "Doctor," she called suddenly, "He feels a little warm."

The Doctor moved over to them, the few feet they'd been separated and looked at the small child that was leaning against his mother. He pressed his hand to the child's cheek and forehead, "It's rather hot on this planet, and he's been walking for several miles, he's likely to be a little warm. We'll keep an eye on him, here I'll take him."

Instantly Jack held his arms out to his father, who accepted the small burden, "You okay Jack?"

"Tired," whimpered the boy.

"Take a nap son, you'll be fine," Rose smiled softly as she watched her husband hold fast to the little boy. Jack glanced back at his mother as he leaned his head against his father's shoulder, his hair flopping around on his forehead.

She spent the next few hours moving from booth to booth buying small things they would need for the next several weeks when she noticed a tiny leather necklace with a beautiful golden star at the end. "Hey," she whispered gently nudging the child resting against her shoulder, "Look at this," she pointed to the beautiful necklace.

Cloudy gray blue eyes turned, still firmly attached to his mother's shoulder, a thumb carefully placed between his lips as he looked at the star. Rose sighed, normally he'd be begging to get it, pointing to it and how cool it looked. He'd be dying to touch it, play with it. His quietness suddenly worried her. "Like that?" she asked gently, trying to prod him into excitement.

Rose looked up at the beautiful alien woman and offered her a pleasantly warm smile, "How much is it?"

"For him, 'tis free," the alien offered as she handed the gift over.

"Oh, no I coul--."

"Please, take it—'Tis rare for us to see such small children around these parts. Please, take the gift."

Rose nodded, offering another warm smile, "Thank you," she replied softly as she accepted the beautiful necklace and slipped it into her pocket. Her worry for her handsome little Timer never fleeting. She looked up and spotted her husband coming towards her with a warm smile all over his face; he glanced down at the small child in his arms and the smile turned into a frown.

"What's wrong?" he asked as he came over to join his wife and son, his brows now furrowed in concern as he gently rubbed the little back of the small body clinging to his wife.

"He's burning up, and he hasn't been very responsive," Rose replied quietly, not wanting to concern anyone on the planet.

The Doctor gently placed his hands under the boy's armpits and lifted him into his arms, turning him around. As he had to his mother, Jack clung to his daddy, thumb back in his mouth as he curled into his father's protective arms, leaning an ear against his chest, listening to the rhythmic pounding of his two hearts. "Hey there little one," he whispered softly, leaning his chin against the boy's head, "I hear you aren't feeling too good?" He felt the sweaty forehead shake against his chest and he smiled sadly, "Well—we'll just have to make you better won't we." Curling both arms around the small body he looked up at his wife and together they headed back towards the TARDIS leaving the small city.

"Doctor, what's wrong with him?" Rose questioned.

Shaking his head, the Doctor unlocked the door and pushed it open, both dipping inside the TARDIS. "I don't know, could be nothing at all. We'll get him settled and I'll check the library. I'm going to put the Tardis on Auto, let it fly through the vortex for awhile."

"I didn't even know Time Lords could become ill."

"'Course we can," the Doctor admonished, "It's just quite rare. Remember though, the lad's only half Time Lord, he has human in him, which makes him more susceptible. Don't worry love; I'm sure he's just fine."

The Doctor carried the boy into the bedroom he and Rose shared; she watched him diligently pull off the child's shoes and socks, his light coat and looked up at his wife. Get him cool, and comfortable, I'll try and be back shortly with something."

"Doctor…"

"Rose, I promise you—I'll get him back to normal," he ran his sonic screwdriver over the child's ailing body. "Get some rest son," leaning down he pressed a kiss to the pale damp forehead and forced a comforting smile.

He left Rose alone in the room with the precious prince. She moved over to the side of the bed, gently rubbing his back as the child slipped into a light sleep. She smiled softly, never in a million years had she imagined herself with a half human half alien child. She didn't ever plan on being married to a wonderful alien she loved with all her heart and soul. She never thought she'd still be traveling through time with him.

Although the ride hadn't been simple, or fun, not by a long shot: they'd worked on their relationship. With her first doctor he'd needed her, as an equal and another person. They'd had a completely different type of love for one another. A type of love she'd thought for nearly a year after the regeneration that this doctor didn't feel for her. She knew now; that wasn't true

She'd been lost without her doctor at first, but she'd come to accept him over time, and even enjoy his company and wit. He was different; he didn't physically or emotionally need Rose in his life, he wanted her. He loved her for being the link she'd been, showing him how to live again. So for nearly twelve years; two of those with Mickey, she'd been with the Doctor. Then four years ago she'd found herself pregnant. She and the Doctor had just begun exploring the early stages of a more physical relationship. Shortly after Jack's birth: named after Captain Jack Harkness, and Rose's father Peter Tyler: they went back to Earth and took their vows.

If anything the marriage and the child had only pulled them closer together, Rose couldn't love anyone more. The Doctor had learned a whole new world of love and pride as he watched his son grow over four years. He'd calmed down and taken the safer paths since their son's birth.

A part of her, however, would always miss her Doctor. She'd fallen in love with him first, but she loved this man too, she always would. Sighing again, she glanced down at their sweet Time prince. They had the perfect baby. He had sandy blonde hair, from both parents. He had the pervious incarnation's gray blue eyes, slightly large ears and perhaps his nose. Rose had bought him a scar in complete jest that the boy carried with him everywhere now, it was red and gray; the child adored the far too long garment. The Doctor also noted on several occasions; Jack's pension for bright colors, which he explained was from the sixth reincarnation. It was one of the few traits that both parents hoped would go away.

Yet Jack was so much like his father and his namesake; just bursting with enthusiasm and love to share with anyone and everyone he met. Reaching out she brushed the hair from his sweat dampened forehead and forced a smile.

He sat quietly in the library, surrounded by books, among piles and piles of them. Glasses had long since been abandoned atop his head. His thoughts strayed to his child, his little Time Lord: it's what he loved to call him. A smile fluttered across his face at the thought of all the adventures they would have together.

He had to figure out whatever it was, and save his son. The child was the future of the Time Lords; he would be the one to start their existence over. He would be the beginning of the Time Lords, a whole new race of them. He could still look back over the past nine hundred years and remember the loneliness, the depression he'd felt for years. Then his dying slowly just by surviving; until he'd met Rose his life had really been depressing and lacking. Now he lived his life strictly for Rose and their little son, his son. He smiled ruefully at that, the child seemed to follow him just about everywhere. Doing everything his daddy did. He adored that little boy, just barely out of toddler hood and already growing up so fast. By the standard age of twelve in human years he would be considered an adult in the eyes of Time Lords, and he would have to make a decision of which race he preferred to be. They would give him the choice; allowing him a chance to make his own decisions.

"Doctor," she called softly.

Chocolate colored eyes glanced up and offered her a weak smile, "How is he?"

"He's worse, he's running a fever and—" she stopped, looking at him.

He spotted the tears in her eyes long before she said anything further; he was up, bounding over the piles of books and out of the room. He ran all the way to their bedroom, terrified of what would cause his strong and beautiful Rose to suddenly cry.

Two blue fever-hazed blue eyes gazed up at him weakly, his face was pale and his lips growing blue, "Daddy," he whimpered as he held a hand out to the Time Lord.

"Hullo little one," scooping his son up into his arms, he didn't have to guess, he felt it the instant he held the tiny child to his chest. His eyes swiveled onto his wife, "How long ago did his heart stop beating?"

"I just noticed," she whimpered.

"Papa," cried the child.

The doctor gently soothed the child, as he rushed out of the room, moving swiftly towards the console room, "Where are you going?" Rose whimpered.

"To the only other person I know in this universe that might be able to help him. I don't have nanogenes anywhere on this ship to save him…"

"Jack…you're taking him to Jack?"

"You have any other ideas?" the Doctor suddenly asked.

She shook her head and watched her husband. He continued to clutch the dying child in one arm and fly the TARDIS in his other arm, "Come on ol' girl," he whispered softly as he stroked one of the panels, spurring the living ship on faster.

"What's wrong with him?"

"I don't know, whatever he has doesn't exist, at least not in any of the books I have, I Rose I told you I'd save him, and I plan on keeping that promise."

o0o

Captain Jack Harkness slowly ran his hands down the curves beneath his fingers, smiling against the lips of the person opposite of him, he inched closer, fingering fabric that was clinging to their bodies. His tongue invading every inch of her mouth.

"Jack!" came a voice from just outside the door.

"I'm busy!" he returned as he continued making his path down the pale white neck and shoulder, gaining moans from the woman he had pinned against a wall.

"Sir…a man walls himself the Doctor is outside…you said you—" Jack cut the boy off as he flew out of the storage closet towards the front desk. He was stunned, there stood a somewhat shorter, skinner man than the Doctor he'd known, with smaller ears and a smaller nose. Brown eyes had replaced the once beautiful steel eyes that he'd fallen for. And he had hair…still a similar color, but he actually had hair.

His eyes landed to Rose, who still looked the same as she had all those years ago when they'd last seen each other on the Game station. He felt his heart race at the sight of how young and beautiful she still looked. That's when his eyes finally fell to the little figure who was struggling to draw each breath, lying in the Doctor's arms.

"What's wrong?" he asked. He wasn't a Doctor, and didn't really pretend to be one, but if Rose and the Doctor were seeking his help after all these years than it had to be something to do with this little child—who looked strangely like the doctor he'd known.

"He's dyin'" Rose offered, "An' you fixed my hand's that one time…we thought you could use your nanogenes again…please," she whispered.

"Of course, you're lucky I just reset everything, brand new, may I?" he asked as he held his hands towards the small child.

"Course," muttered the Doctor.

Jack took the little figure into his arms and was stunned, he looked so much like the Doctor, Jack had known. Poor kid was never gonna live his ears and nose down. He turned and hurried back through the corridors of the small hospital. "How did you know where I was?" Jack asked suddenly.

"We've kept tabs on you Jack, ever since the day we left…at first we didn't think you'd survived. Then we heard about Torchwood."

"I came here three or four years ago, settled down—if that is even possible for me, I've been working on the nanogenes for years now—since you left. They're not perfect Doctor…not by any means."

"Jack, just do your best," Rose whispered.

o0o

Rose watched her son, sitting by his side as he was surrounded by the golden lights that had healed her hands back in 1941. She smiled softly, seemed like ages ago. The Doctor and Jack sat by one another talking quietly; the Doctor had set to explaining his latest look.

"So he's yours then?" Jack asked softly as he came to stand beside the little child.

The Doctor wrapped an arm around his wife's waist and smiled sadly, "Yeah he's ours," he replied.

"What's the guy's name? I didn't even think to ask," smiled Jack.

"Jackson Peter Tyler—we call him Jack," Rose replied eyeing her friend.

The dark haired ex-time agent just grinned as he looked back down at the boy. The machine chirped, breaking their comfortable silence and the nanogenes returned to where they'd come from.

"Well?" Rose whispered.

Jack pressed his hand over the boy's two hearts and smiled softly, "Vitals feel better. Both hearts are beating…I think he's going to make it. He should wake up soon." Jack didn't miss the look of desperation and gratitude in Rose's eyes; he quickly made a mental note to ask her about it late, and this Doctor.

o0o

They spent the next several hours waiting for the small boy to wake up, before Jack finally convinced his beloved Rose to take a short walk with him. The Doctor could handle the little boy just fine, especially when the kid was unconscious.

"So…how ya doin?" He asked once they were out of the Doctor's ear shot.

"What do ya mean?"

"Rose, you and I both know that's not the face of the man you fell in love with. That's not our Doctor."

Rose shook her head, "No, it's not, at least not physically, but our Doctor's in there somewhere Jack."

"What happened?" He asked gently taking her hand into his. He loved her; he would always love her, just like he would always love their Doctor.

She glanced down to her shoes, feeling tears returning to her eyes after all these years, "I killed him," she whimpered.

"What? How?" he asked as he slid his hands to her neck and lifted her face so he could see those beautiful eyes the Doctor had adored so deeply.

"Member when the Slitheen thing looked into the Time Vortex?"

"Vaguely," he smiled, he remembered the day better than anyone should, but he allowed her to continue.

"The Doctor sent me away from the station, sent me home as a safety precaution..."

"Program One, I'm aware of it."

"You are?"

"Honey, he wanted what was best for you; he knew I didn't agree with it, but he made a promise. You know how he was. If he could keep a promise he did."

"Anyway, I didn't take kindly to being sent back to earth. I broke the TARDIS consol open…and looked into the time Vortex. I'm the one who killed the Dalek, the one who gave you life…who killed my Doctor," she sobbed.

Jack sighed as he pulled her into his arms, "Rose, he wouldn't want you to hurt like this, not after all this time. What about this Doctor? What happened?"

"The Doctor took the Time Vortex into his body…it caused every cell in his body to start dying, so he regenerated and became this doctor. Jack, it's not the same, I love him really I do. But I miss my Doctor, my first true love, the man who looked at me as though I was his entire world and then some."

He smiled softly as he gently rubbed her back, "Your son looks so much like our Doctor, he's still here Rose. He's with you every moment, you just don't see him. This Doctor loves you too."

"I know, but--."

"I understand, it's not the same, how could it be. I'm sorry Rose, and I know part of him is too. He loved you."

"I know he did, and Jack I just miss him so much."

"Shh, I'm here now; want me to come back with ya?" he asked.

She chuckled softly against his chest, "Realize how confused that would get," she grinned as she sniffled and pulled away from the broad chest of the man she'd come to see as a brother.

"Yeah, you're probably right. If you ever need me Rose, you know where I am; don't be afraid to ask for help. And bring Jack around; I'd love to get to know my nephew."

"I will, thanks Jack," she whispered softly, "And thank you for saving him."

"Hey I just did the easy part, the rest was up to. Give him my sympathy as he grows up with those ears."

"Stop making fun of my son!" giggled Rose, feeling like she had so many years ago with her Doctor.

Their arms around one another they slowly made their way back to the infirmary. Rose smiled as she spotted her son sitting up in the bed, looking much better than he had when they'd first brought him here nearly fifteen hours ago. His face immediately brightened at the sight of his mother. Both Rose and Jack felt the air leave their lungs.

"My God, he looks exactly like him," whispered Jack when he saw the toothy grin.

Rose realized at that very moment that her son did look like her former Doctor. The sparkling eyes, the big ears, big nose, beautiful smile. And just like the Doctor, a smile he only truly showed to her or at the sight of her.

"Hey sweetheart," whispered Rose as she moved over to her only son and lifted him into her arms. Both clutched to one another, and she suddenly realized what a godsend this little boy was. Someone had to be watching over them, and sent him to help her deal with everything a little easier. "Thank you," she whimpered to no on in particular.
