"Aunt Jackie?"

Lily opened her room door, pulling her long brown hair up into a bun, noting the Christmas decorations hanging all over the apartment. Aunt Jackie had been busy decorating the whole place, saying how she was going to have everything perfect for when Rose came home. Lily had never really understood what she meant exactly, since Jackie and Rose's boyfriend Mickey had never exactly told her where Rose had gone and why it seemed to be uncertain when she'd return. All she knew was that Rose had disappeared, and if Aunt Jackie was to be believed it was some doctor's fault. Mickey had confided in Lily that Rose had left to help this doctor but that she might not come back, and warned her to be ready to comfort Jackie if it came to that.

"Aunt Jackie?" She called again.

"In here, sweetheart." Jackie's voice sounded from the lounge and Lily wandered in, spotting the decorated white Christmas tree in the corner and the present Jackie was holding in her hands, with the label: "To Rose, Lots of Love Mum."

"What's the matter? Do you need anything?" Jackie asked, and Lily gave a small smile, hearing the forced cheer behind Jackie's voice. "I was just going to brew some tea, and I was wondering if you wanted some too." Lily said quietly. "Some tea would be lovely, thanks sweetheart." Jackie sighed.

"Aunt Jackie…" Lily moved next to her aunt, hugging her. "I'm sure Rose is fine, wherever she is. She's a strong girl, and she'll be back home before you know it." Lily encouraged. Jackie laughed, shaking her head. But before she could respond, Lily heard the most curious noise coming from outside. It sounded like a wheezing whooping sound, and Lily wondered if she was going crazy when Jackie stiffened. Before Lily could ask her what was wrong, Jackie gasped: "Rose!" and went dashing out the apartment. Lily followed immediately, confused as to what on earth the sound could have to do with Rose.

Outside, Jackie was looking around and up into the sky (Why the sky? Lily wondered) when Lily spotted Mickey running towards them from the opposite end of the street. "Mickey!" She called, and Jackie started running towards him also calling his name.

"Lily!" He called back and went rushing towards Jackie, saying: "Jackie, it's the Tardis." "The what?" Lily asked as Jackie cried: "I know! I know! I heard it! She's alive, Mickey! I said so, didn't I? She's alive!" "What do you mean, 'She's alive'?" Lily asked alarmed. "Why wouldn't she be alive!?" "Just shut up a minute!" Mickey shushed her and Jackie, both of them looking upwards and around desperately for the source of the wheezing. Lily looked around too, wondering what on earth was going on as Jackie asked: "Well, where is it, then?"

At that moment, there was a crackle as an electric pulse occurring in the sky right behind them and Lily's jaw dropped as a blue police phone box came flying out of thin air. She and Jackie gasped as the box slammed into a nearby building before they all screamed as it careened violently and almost took their heads off as it flew over their heads. Lily screamed as the box almost collided with a van driving down the road, before it veered again, crashing into several buildings before eventually tumbling around the corner and coming to an abrupt halt.

Lily, Jackie and Mickey ran towards the box, Lily arriving first as she had been closest. Just as she turned the corner, the door flew open and a tall man in a leather jacket, who looked in his early thirties popped his head out. He looked about six feet, given that he was a little over a head taller than Lily who stood at about five foot six.

"Here we are, then. London, Earth, the Solar System, I did it!" He yelled rather breathlessly as he stumbled out, the door creaking shut behind him. He turned and spotted a flabbergasted Lily. "Who are you, then?" He asked curiously, inspecting her with dark brown eyes. "Lily…" Lily answered slowly just as Jackie and Mickey arrived.

"Jackie, Mickey! Blimey!" The strange man cried. "No, no, no, no. Hold on. Wait there, what was I gonna say?" He panted as he stumbled around. "There was something I had to tell you, something important. What was it? No, hold on. Hold on. Sh, sh, sh, sh!" He mumbled as he grasped their shoulders. Lily watched this erratic behavior with wide eyes, just as the man cried out euphorically. "Oh! I know!" He looked between them excitedly and said rather breathlessly "Merry Christmas!" before suddenly collapsing. Lily gasped and she and Jackie rushed worriedly towards the man as Mickey caught the man and gently lay him down on the ground. At that moment, the door to the police phone box creaked open and Lily looked up startled to find she was staring at her cousin.

"Lily?" Rose asked incredulously as said girl blinked in surprise before she noticed the unconscious man on the ground beside her teenage cousin. "What happened? Is he all right?" She asked as she knelt down beside them. "I don't know, he just keeled over." Mickey stammered as all of them looked down at the man worriedly. "But who is he? Where's the doctor?" Mickey asked as Lily looked at him confused. "What doctor?" Rose answered Mickey, ignoring Lily's question. "That's him. Right in front of you. That's the doctor."

"What doctor?" Lily repeated, as Jackie asked confused: "What do you mean, 'That's the doctor'?" As Rose opened her mouth, Lily asked exasperated: "Doctor who?!"

Rose looked at her, and Lily noticed how sad her cousin looked. "I don't think I know anymore." She said softly. They all looked back down at the man, and it was then that Lily noticed that the man's clothes seemed to be ill-fitting. Both the leather jacket and the shirt were too baggy for the thin man's frame, and his pants also looked loose on him. It was as though he had borrowed the wardrobe of another man. Lily was interrupted out of her thoughts as Rose sighed and said: "Come on, help me carry him upstairs."

Between Rose, Lily and Mickey, they managed to haul the man up and carried him into Jackie's apartment while Jackie rushed ahead, clearing their paths and opening doors. They finally lay him gently down in the spare room Lily was staying in. Lily groaned as she stretched her arms, the man was heavier than he looked. "Right, I'll call 911." Jackie declared, moving towards the landline.

"No." Rose murmured, staring down at the man. "What?" Jackie asked. "No, we can't take him to a hospital, it'll attract too much attention and they wouldn't be able to help him anyways. Just get me something to examine him with" Rose muttered. Lily looked over at Rose, and noticed how her cousin was staring at the man like a lost child, while Mickey was staring at Rose with an unreadable expression. Lily sighed quietly as she felt the tension in the room continue to thicken, before jolting Rose and Mickey out of their thoughts by remarking softly: "We should get him into pajamas or something comfortable so he can rest better." Rose nodded thoughtfully and Lily turned to Jackie standing in the doorway.

Together they rummaged in Jackie's room, getting Howard's jammies and dressing gown. Mickey helped Rose change the man, whom everyone seemed to be calling "the doctor", and soon he was resting peacefully in the bed. While that was going on, Lily began to make everyone some hot, calming tea and Jackie ran over to Tina's to borrow a stethoscope from her medical school lodger. Rose stayed sitting beside the doctor while Mickey stumped glumly into the lounge and sat down on the couch. Just as Lily was pouring out the tea into mugs, she heard the door slam again, signaling Jackie's return. Lily placed all the mugs on a tray, carrying them towards her room. She stopped on the way to give Mickey one, which he accepted with a murmur of thanks, and then peered into the room to see Rose placing the stethoscope… on the right side of the man's chest.

"Both working." She declared with some relief, causing Lily to furrow her brows in confusion. She wasn't the only one, Jackie frowned at Rose as she asked: "What do you mean 'both'?"

"Well, he's got two hearts." Rose answered as if it was obvious and Lily stared at her cousin, wondering if she had hit her head when she hadn't been looking. Then again, she had arrived in a flying blue box, so Lily supposed anything was possible at this point. Jackie clearly hadn't reached this conclusion as she scoffed at her daughter. "Oh, don't be stupid." "He has." Rose defended as she got up off the bed, and gave a small grateful smile as Lily handed her a mug of steaming tea.

"Anything else he's got two of?" Jackie asked apprehensively, and Rose turned in exasperation and exclaimed "Leave him alone" before going down the hall. Jackie followed quietly and took the offered mug from Lily with a quiet "Thanks sweetheart." She paused and looked back at the man uncertainly. "I'll stay and keep an eye on him." Lily said quietly, and Jackie nodded gratefully. Truth be told, Lily was also worried about both this man and Rose, but she knew Jackie would want to check on her daughter. Lily stepped in, grabbed a book off the bedside table, set the tray down in its place and sat on the floor by the door.

She stared at the man, taking in his features. He had brown hair that was sort of windswept up and out of his face, and sideburns down the sides of his thin face. Lily thought back to Rose's statement, how he had two hearts. She looked back at the man and remembered his eyes, recalling how dark and impossibly old his eyes had been. Did that then mean he wasn't as human as he seemed? At that moment, the man gave a slight sigh, releasing a wisp of gold light. Lily gapped in amazement, as the golden particles slipped out the crack in the window. Ok, definitely not human. She thought as she glanced between the man and the window. She watched to see if anything else happened, but as he just continued to lie there peacefully, she settled down to sip her tea and read her book.

Sometime later, Mickey came by, asking how she was. Lily glanced at the strange man in her bed, before murmuring she was alright. Mickey came in and slid down to sit beside her. "Come on," he said, "What's going through that head of yours?"

Lily smiled slightly, before sighing and looking back at the strange man. "Who is he? Why do you guys call him 'the doctor'?" She asked. Mickey sighed as he glanced at the Doctor. "Because that's what everyone calls him, apparently." He responded. "What, his parents actually called their son 'Doctor'?" Lily asked, frowning. Mickey laughed. "Nah, I think he has a name, but no-one knows what it is, so he's just the Doctor. I don't think even Rose knows his real name."

"What was Rose doing with him? And what was that blue box?" "She's been travelling with him, and that box is called the Tardis. It's the Doctor's time-travelling machine, it stood for something but I don't remember what." Lily laughed as Mickey shrugged. "So this doctor is a time-traveller? What does he do, go around helping sick people in different time periods?" She asked, intrigued and Mickey laughed. "Nah, he goes around saving people from different planets." Lily stared at him, and Mickey grinned at her somewhat skeptical face. "Like aliens?" She asked. "Exactly like aliens. He's an alien too, a Time Lord, whatever they are." Lily's eyes widened as she stared at the alien on her bed. "Go on…" she encouraged, and Mickey sat and told her what stories he could that he'd heard from Rose.

Time flew by, and before they knew it, it was evening when Rose popped her head in to say she was heading out to buy her mum a Christmas present. Mickey quickly offered to join her while Lily simply nodded but she couldn't help but notice that Rose seemed intent on not looking in the direction of the bed. Soon after, she heard the door open and close, and she settled back down into her book. Just as her butt was beginning to get numb, she heard someone knocking on the door and Jackie answering. Lily got up and, after checking on the Doctor and appreciating the irony of the situation, she wandered out to see Jackie struggling with a Christmas tree by the door. She quickly placed her mug and book on the table in the living room, and hurried back to help Jackie haul the tree through the hall and into the lounge.

"What's with the tree?" Lily asked as Jackie began to move her white tree out of the room to make space. "I dunno, I suppose Rose bought a new one." Jackie shrugged as she discarded the old tree and placed the new one in its place. "Why would she do that?" Lily wandered just as the phone rang. Jackie answered, squealed a greeting to Bev and began gossiping with her. Lily sighed. One day that phone, and all her time on it, is going to be the death of her. Lily thought, as she moved her mug into the kitchen and wandered back into her bedroom. She paused as she noticed the gold particles again, floating out the window. She frowned, and moved to check the man's forehead, wandering if this was normal for an alien man. Just then the door burst open and Lily jumped as Rose ran in crying for Jackie to get off the phone.

"What on earth?!" She gasped as Mickey raced in after Rose, slamming the door shut while Rose snatched the phone off her mother. "Lily!" Mickey gasped and Lily stared at him from her bedroom doorway. "Oh my god, Lily! We just got attacked by Santa!" Lily stared at him as he rushed into the living room like he'd grown two heads.

"What?" Lily asked as she followed Mickey, not believing her ears as Rose hung up the phone. "Right, it's not safe, we've got to get out." Rose declared. "Where can we go?" "My mate Stan, he'll put us up." Mickey answered immediately. "That's only two streets away." Rose frowned. "What about Mo? Where's she living now?" Lily snorted as Jackie shrugged. "I don't know. Peak District."

"Well, we'll go to cousin Mo's then." Rose stated and Lily sighed. "With an unconscious man? Mo'd eat him alive if he's still sober enough to be awake." Lily grumbled as Jackie protested: "No, it's Christmas Eve! We're not going anywhere! What're you babbling about?" "Mum!" Rose cried desperately. "Apparently they got attacked by Santa?" Lily offered. Jackie stared at her niece as Rose noticed the new Christmas tree. "Where'd you get that tree?" She asked, and they all turned to peer at the tree.

"That's a new tree. Where'd you get it?" She asked suspiciously. "I thought it was you?" Jackie relied confused, and Lily's heart sank- that could not be good. "How can it be me?" Rose asked just as confused. "Well, you went shopping. There was a ring at the door, and there it was!" Jackie said and Lily groaned. "This can't be good" she moaned as Rose said slowly: "No, that wasn't me."

"Then who was it?" Jackie mumbled just as the tree started to light up by itself. "I told you it couldn't be good." Lily gasped. Rose pulled Jackie slowly away as Lily backed slowly towards the hall. "Oh, you're kidding me." Rose sighed and the tree started to play Jingle Bells before the different sections of the tree starting to rotate in different directions. The song blared as the tree picked up speed and creating a strong wind that caused Jackie to start shrieking. "Oh my god!" Lily shrieked as the tree started moving towards them, sawing through everything in it's path.

"Go, go! Get out!" Mickey yelled, and Lily didn't need to be told twice. She ran from the room, straight to her bedroom and stopped next to the man, followed quickly by Rose who stopped in the bedroom doorway as she cried: "We've got to save the Doctor!" "What're you doing?!" Jackie cried and Rose looked at her. "We can't just leave him."

With that Rose rushed in the room next to Lily, pulling on the man as Jackie yelled: "Mickey! Leave it! Get out! Get out!" Lily moved to help her cousin, just as Rose leapt to the door, calling for Mickey as Jackie screamed for him to get out of the living room. Just as Rose came back next to Lily, who was trying to haul the man up into a sitting position, Mickey rushed in against Jackie's cries to leave the man. "Get in here!" Mickey yelled at her, and Jackie quickly complied screaming while Lily's grip faltered and the man fell back down.

"Doctor, wake up!" Rose cried, as Jackie and Mickey dragged the wardrobe across to block the door. Lily leapt up to help them brace the wardrobe as it began to shake against the tree's efforts to enter, and Rose rummaged through the Doctor's leather jacket. "Rose, a little help!" Lily gasped while Jackie continued to scream. Lily watched as Rose pulled something like a metal pencil out of the leather jacket and rushed back to the Doctor's side, placing the tool in his left hand.

"What good will that do?" Lily cried just as she felt the wardrobe give a final quiver before it burst apart, throwing Jackie and Mickey to either side and causing Lily to fly across the room and land on the doctor. Rose was pushed back by the wind as the tree flew into the room. Lily raised her head to see Rose staring in terror behind her, and looked around to see the tree heading straight for them.

"I'm going to be killed by a Christmas tree!" Jackie squealed in fear, and Lily turned to the pale face of the Doctor. She hesitated, before drawing a deep breath and bent down and whispered in his ear. "Please, help us."

Immediately, the man bolted upright, causing Lily to fall off his chest and into his lap as he raised his arm and pointed the strange tool at the tree. Immediately the tress burst into flames, disintegrating on the spot. There was a stunned silence as everyone gasped to get their heart rates down and they all stared at the Doctor as he slowly lowered his arm.

"Remote control." He stated. "But who's controlling it?" He leapt out of the bed, causing Lily to fall onto the floor with a yelp. He paused and looked back at her as if just noticing she was there. He quickly helped her up before grabbing Howard's dressing gown and walking out the front door, the rest of them following quickly. Lily noticed that Rose kept staring at the Doctor intently, as though she was searching for something. He stopped just outside, and Lily peeked down to see what he was looking at. She started when she saw three Santas standing below in the parking lot, one of them holding a radio controller.

"That's them," Mickey spluttered, "What are they?" "Sh!" Rose shushed him, watching the doctor warily. Lily was also watching the Doctor as he raised his arm, pointing his tool (which she now saw was some kind of screwdriver) at the Santas. Immediately, they backed away, before suddenly disappearing in pillars of light.

"They've just gone." Mickey said in wonder, before he gave a derisive snort. "What kind of rubbish were they? I mean, no offence, but they're not much cop if a sonic screwdriver's going to scare them off." "Sonic what?" Lily asked. As Mickey was opening his mouth to reply the Doctor said darkly: "Pilot fish."

"What?" Rose asked. "They were just pilot fish." The Doctor murmured before he suddenly gasped, clutching his chest as he fell back in pain. "Are you alright?" Lily asked in alarm, as Rose said at the same time: "What's wrong?" "Does it look like I'm ok?." The Doctor groaned. "You woke me up too soon. I'm still regenerating. I'm bursting with energy." He let out another breath of the golden light. "Yea, you've been doing that for a while." Lily said nervously, and the Doctor looked at her properly for the first time.

"Well, the pilot fish could smell it a million miles away. So they eliminate the defense, that's you lot," he motioned at the four of them, "and they carry me off. They could run their batteries on me for a couple of ow!" He cried in pain, grasping his chest as stumbled forward, leaning against the railings as he squeezed his eyes shut. Jackie hurried over and placed her hands on his bend form as she tried to help him.

"My head!" The Doctor groaned. 'I'm having a neuron implosion. I need…" Jackie interrupted "What do you need?" "I need…" The Doctor tried again. "Say it. Tell me, tell me, tell me." Jackie cried in panic. "I need…" The Doctor tried again. "Painkillers?" Jackie suggested and Lily looked at her incredulously. Was she serious? "I need…" The Doctor squeezed his eyes shut again. "Do you need aspirin?" Jackie interjected again and the Doctor groaned. "I need…" he gasped as he stared at Jackie. "Codeine? Paracetamol? Oh, I don't know, Pepto-Bismol?"

"Does she even have all of that?" Lily asked and Mickey shrugged as Rose stared on in silence. "I need!" The Doctor tried but Jackie continued. "Liquid paraffin. Vitamin C? Vitamin D? Vitamin E?" "FG" Lily mumbled and Mickey snorted while Rose rolled her eyes. "I need!" The Doctor gasped but Jackie rode on over him. "Is it food? Something simple. Bowl of soup. A nice bowl of soup? Soup and a sandwich? Soup and a little ham sandwich?"

"I need you to shut up!" The Doctor finally gasped out annoyed, shoving past Jackie to lean on the opposite wall. "Oh, he hasn't changed that much, has he?" Jackie grumbled as Lily stepped forward to grab the Doctor as he continued to clutch at his chest. "We haven't got much time." He groaned out between gasps of pain. "If there's pilot fish, then… Why's there an apple in my dressing gown?" He asked suddenly, pulling the fruit out in confusion and holding it before an amused Lily.

"Oh, that's Howard. Sorry." Jackie replied. The Doctor looked at her like she was crazy. "He keeps apples in his dressing gown?" "He gets hungry." Jackie shrugged. "What, he gets hungry in his sleep?" The Doctor asked derisively, and Jackie answered seriously: "Sometimes."

"Is this important?" Lily interrupted. The Doctor looked at her again, and as he opened his mouth he suddenly yelled in pain. "Argh!" He stumbled and fell down, grasping Lily's arm to prevent himself from falling face first." Brain collapsing." He slide down the wall. "The pilot fish!" He gasped out, reaching out to grab Rose with his other arm, pulling both girls in front of him and looking at them very seriously through his pain-laced eyes. "The pilot fish…" he groaned in pain, "that something… something…" He continued to gasp in pain as he struggled to get his words out. "Something is coming" and then he passed dead out as Rose and Lily stared at each other.
