Hey, everyone. I've still been seeing Story Alerts for Sherlock, John, and the Doctor when I've finished it up and moved on to its sequel, Sherlock, John, and the Doctor: Series Two in a separate story. I wanted to split these stories up between Doctor Who series, because of how long these stories can get, novel-length at times.

So I'll post a preview on here of the first chapter from Sherlock, John, and the Doctor: Series Two, which you can search for here on FanFiction and read some more. I couldn't post a web link to that story because FanFiction won't let me, but it is out there, just search for it here.

However, if you really want me to keep using Sherlock, John, and the Doctor to post the rest of Series Two, I might consider doing that with prompting. But I do find it rather bulky or unwieldy when this story might grow to the length of two novels and more if I continue with the rest of the show here. I still prefer to post separate stories for each series of Sherlock, John, and the Doctor.

Anyway, here it is, and Merry Christmas:

Sherlock, John, and the Doctor: Series Two

1. The Invasion Begins

Hello, and welcome to Series Two of Sherlock, John, and the Doctor. For those of you who read Series One, welcome back, and for those of you checking this out for the first time, this is Series Two of Doctor Who with Sherlock, John, and everyone in their orbit getting involved in the Doctor's adventures. So here we go with the Christmas Invasion!

Sherlock, John, and Rose were practically knocked out by the TARDIS's rough landing on the Powell Estate on Christmas Eve. It took a couple minutes for them to recover while the newly regenerated 10th Doctor staggered out and greeted a confused Jackie Tyler and Mickey Smith before he passed out right in Mickey's arms.

However, once he had regained enough of his senses, Dr. John Watson sprang into action, ordering Mickey to help him take the Doctor up to Jackie's flat. He was still riding the adrenaline high he had received helping out the 9th Doctor on the Gamestation while people were dying all around them from the Daleks.

It had been a horrible experience, the worst of his life even fighting in Afghanistan, but he was still energized by it, nonetheless. One of those paradoxes in his confusing life, he wouldn't be able to sleep a wink tonight, especially thinking about what had almost happened to Rose and Sherlock.

And maybe he would have a nightmare or two of being stripped naked on What Not to Wear next to Captain Jack Harkness, who apparently wasn't dead and had been brought back to life, according to Sherlock. John was a bit shocked by that and wondering why they had left Captain Jack behind and how his future self, Future Jack, had wound up saving their lives in Cardiff when the Rift was acting up. It didn't make sense, or maybe it would if John could get to the bottom of it.

Rose explained the situation as best she could to Jackie and Mickey and pitched in to help, though she was still overwhelmed by the Doctor's regeneration as well. It had been a terrible day or two for her, being trapped on The Weakest Link, then kidnapped by Daleks, threatened with annihilation, tricked into going back to Earth along with Sherlock, arguing with her family, trying to pry open the TARDIS, and then whatever the hell happened to her and Sherlock and now the Doctor had changed…and it was Christmas Eve. Ugh, an absolute nightmare.

John turned to Sherlock Holmes, strolling out of the TARDIS with his mobile in hand. Sherlock had also grabbed his laptop and John's medical kit. Despite having been a part of Bad Wolf with Rose and being stuck on Big Brother with the Doctor earlier, Sherlock appeared none the worse for wear, though there was a certain glow about him.

Maybe it was just the love that John felt for him, maybe it was an aftereffect of Bad Wolf, maybe it was Sherlock's excitement at having witnessed an actual regeneration, or maybe it was this new adventure that they were setting out upon with this new Doctor. Sherlock was always rejuvenated and excited, aroused, too, usually, whenever something popped up to relieve his boredom.

It used to be just mysteries, but now traveling with the Doctor had become Sherlock's drug of choice, for lack of a better term, that thrill and high of adventure. John wasn't always so keen on such dangerous adventures, but Sherlock pulled him along and they had fallen in love in the midst of all this.

And John couldn't abandon his friends, the Doctor, Rose, and even Captain Jack, too. They had become a tight-knit family, and though John might have thought about leaving someday while Sherlock would prefer to travel with the Doctor forever…that was still something that had to be worked out between them.

"I need all of the UNIT files they've got on the Doctor's past regenerations, medical and otherwise, and I might need some more supplies." John started to tell Sherlock.

"Got it. Texting my brother to bring over the information and some equipment." Sherlock said, his fingers flitting across his mobile's keyboard. "Also texted Ms. Hudson to bring over some supper. I don't think Ms. Tyler was expecting company."

"Certainly not. I haven't got a thing in the cupboard, not for all of you." Jackie said, looking around. "Is Ms. Hudson good?"

"The best. You'll be pleased with her cooking." Sherlock smiled. "She's our landlady, but a friend foremost as well."

"Oh, that's good, then." Jackie nodded, a little satisfied.

"Oh, Molly!" John said, turning back to Sherlock. "Text her as well, please, I could use some assistance if there's any trouble."

"Can't forget about Molly." Mickey nodded. "She's been forgotten about enough, like me."

"Got it, will do." Sherlock said, tapping on his keyboard. "Should I add Lestrade?"

"Might as well, though would he come with your brother?" John asked.

"Probably. I think they're an item now, as the phrase goes." Sherlock said.

"How many people are coming to my flat?" Jackie asked. "I haven't got room for everybody!"

"Uh, counting all of us, including the Doctor, I think that makes ten. Eleven if Anthea comes as well. Better tell Ms. Hudson to bring a lot of food. Just in case." Sherlock said, his fingers flying.

Jackie groaned and complained about the crowding, but she accepted it well enough. They got the Doctor settled down in one of the bedrooms in Jackie's flat, John doing a quick examination of the Time Lord with his limited supplies as Sherlock researched the old files he had on his laptop from the first time they heard about the Doctor.

"No aspirin!" Sherlock shouted at John.

"Yes, I remember that." John told him.

Jackie, Rose, and Mickey hung out together, talking quietly, and then the doorbell shortly rang. Jackie answered, glaring at Mycroft Holmes standing on her doorstep with his assistant Anthea and Greg Lestrade standing just behind him. Between the three of them, they had carried some medical supplies and a folder of files.

"Hello, Ms. Tyler." Mycroft smiled, bowing his head and holding out his hand. "It's so nice to meet you."

Mickey stiffened, remembering the last time he had seen Mycroft face to face when the man had interrogated and tried to recruit him at the same time. Jackie grimaced as she gripped Mycroft's hand and shook it as hard as she could.

"Can't say the same, I'm afraid. I've heard all about you, Mycroft Holmes." She nodded at the others. "Detective Inspector Lestrade, Anthea, hello again. Welcome back."

Rose looked down, embarrassed with the way her mum was acting. Admittedly Mycroft was tough, but he could be a good person as well. She nodded and waved at Mycroft, Lestrade, and Anthea, not really feeling like talking.

"Hello," Anthea said, simply waving at Jackie and Rose before ignoring them for a moment as a bit of old, forgotten business.

Lestrade told Jackie, "I'm sorry about all of this mess. Sorry about last time we met, too. Didn't know what was going on."

"It's all right, I suppose." Jackie sighed and stepped back, allowing them entry. "Welcome to my flat. It's not much, but it's home."

"A nice place. Have you redecorated?" Mycroft asked as he and the others entered, bringing in all of their gear. Mickey and Rose helped out.

"You would know, Big Brother." Sherlock remarked, looking up from his laptop. "Have you got the stuff?"

"Just like you ordered." Lestrade said.

John paused his examination of the Doctor to look over the medical supplies and warmly greet Lestrade and Mycroft. He also waved at Anthea, who waved back at him.

Rose went off to check on the Doctor with no one else watching him. Sherlock joined the others, snatching the files away from Mycroft and browsing through them as he coolly, yet cordially greeted Mycroft, Lestrade, and Anthea.

Admittedly Sherlock's relationship with his brother had improved over the last few months, especially with the scare that Mycroft had gotten when he seemed to have been hypnotized. Which reminded Sherlock of the hypothesis Mycroft had come up with as to why or how he had been so hypnotized.

"Have you gotten any closer to finding out more about Moriarty?" Sherlock asked Mycroft and Lestrade. "Do you have any clues as to who he is, alien or human? Or are you still tied to the Master theory?"

"What Master theory?" John asked, looking up at Sherlock. "Are we talking about the Master, the Time Lord who tangled with the Doctor and UNIT in the past?"

"The very same person." Sherlock said, turning to John. "The methods were recognized by the Doctor, even if he didn't want to admit them at the time. Mycroft has been researching, and he thought such hypnosis fit the Master's M.O. in the past."

"God, that would be a nightmare." John said, remembering all of the stories.

"There's a very large criminal network under Moriarty's umbrella." Mycroft said. "Lestrade has been helping me figure out all the strands and block such activity. I still haven't found the leech or spider at the center of the web, but we're getting close. As to who that person is, alien or human or the Master even…well, I wouldn't discredit the theory that there's more to this person or network than meets the eye."

"No solid proof, in other words." Sherlock said.

"We're getting there, one of these days, Sherlock." Lestrade huffed, annoyed. "It would help if you were around to pick on some of these strands. We have a few leads-"

"Not right now." Sherlock said, shaking his head. "We're busy at the moment, after all, dealing with the Doctor."

"Yes, always the Doctor." Mycroft rolled his eyes. "Honestly, Sherlock, if I had known you would get so wrapped up into him, I never would have sent you those files in the first place."

"Well, I'm certainly glad you did. Thank you very much." Sherlock told his brother.

At that moment, the doorbell rang again, and Molly and Ms. Hudson came in, carrying bag after bag of food, flabbergasting Jackie.

"Hello, Sherlock, John!" Ms. Hudson cried, hugging her boys. "And Lestrade and Mycroft too! The rest is in the car." She told the others in general as they greeted her. "This is all I could bring on such short notice for so many guests! Oh, what a lovely holiday this has turned out to be, all of us together again! Where is that Captain Jack? He still owes me a kiss." Ms. Hudson said, patting her hair down.

"I'm sorry to disappoint you, Ms. Hudson, but we had to leave Captain Jack behind." John told her.

"Oh, bollocks. Just when I was getting my hopes up." Ms. Hudson sighed.

"Hello, Molly," Mickey smiled, hugging his friend he met on the way to Cardiff.

"Hi, Mickey! How's it going?" Molly asked him, and they started chatting about their lives.

"This is all you could bring? It's enough to feed an army!" Jackie cried, facing Ms. Hudson.

"Well, you can never have too much food, especially with so many people." Ms. Hudson remarked, juggling her bags. "Can you give me a hand please? Sorry to intrude like this."

"All right, I'll help. I think my gran would have liked you." Jackie said, begrudgingly smiling as she grabbed a couple of Ms. Hudson's bags. "The kitchen is this way, come on, let's set up some of this stuff."

"Good, thanks. Careful with the whiskey!" Ms. Hudson called out.

"Whiskey? Now that's more like it!" Jackie said as she and Ms. Hudson both laughed, Molly soon following them to the kitchen to drop off bags.

"Oh dear, this won't end well." John murmured.

Lestrade, Anthea, Mickey, Mycroft and Sherlock went downstairs to fetch the rest of the bags while John returned to monitoring the Doctor with Rose by his side. Rose glanced up when John came back into the room, then looked away as he checked the Doctor's vitals once more.

"Sure you don't want to…" John hesitated, not certain what to say to Rose. "Go out there or something?"

"It's all right. I'm staying here." Rose said.

"I'm sorry about everything that's happened, but that doesn't mean you should lock yourself up either." John said. "I mean, it's Christmas Eve and we're back home with our friends and family, safe and sound. The Doctor is fine enough, it's just that he hasn't woken up."

"Why hasn't he?" Rose asked.

"Not quite sure." John said. "He's stable enough. His vital signs are normal. Maybe his body is just resting after the strain he's been through. I've been checking all the UNIT logs, and the last two times they witnessed a regeneration, he was out like a light for several hours and then just woke up, no reason really, no prompting necessary. Pretty soon he was back in action, dealing with another threat in his own unique way."

"That's a relief, I suppose." Rose sighed. "I'm just worried about him, that's all, the way he is now and how he's changed. Do you think he still…likes us, I suppose? That he hasn't changed too dramatically?"

"I'm sure he does. He's still the same Doctor, just a little different." John said.

Rose nodded, a little satisfied, and she soon left the Doctor's bedside. Molly came into the room, was apprised of the situation by John, and helped John run some tests and look through files.

Meanwhile, Lestrade, Anthea, Mickey, Mycroft and Sherlock returned with the rest of the bags as Mycroft apologized to Mickey for having arrested and interrogated him several months earlier, mollifying the young man as much as he could.

Ms. Hudson and Jackie were already celebrating Christmas Eve, eating, chatting, and drinking as they set out the spread, and soon the others joined in. Within an hour, Lestrade, Anthea, Mickey, Mycroft, Sherlock, Ms. Hudson, Jackie and even Rose were eating, drinking, chatting and carousing with a couple plates and non-alcoholic beverages passed over to John and Molly in the Doctor's room.

"Oh, by the way, Mycroft, congratulations on getting Harriet Jones elected prime minister." Sherlock saluted his brother. "That's a real coup for you."

"Think nothing of it, Ms. Jones and the British people did all the rest." Mycroft remarked. "I'm certainly glad she has done so well, of course, thanks in part to my tutelage. Hopefully that Guinevere One space probe will also be a success, too. I doubt it will do much for space exploration, but now at least we have our own space probe in the sky."

Sherlock laughed and they chatted a little bit about the space probe and Harriet Jones before they went back to their own celebration. Ms. Hudson was reminiscing about the boys she had kissed in the past while Jackie shared her own saucy tales, causing them both to laugh.

Lestrade and Mycroft were making out in the corner while Anthea sent out some lurid messages, giggling as she texted. Rose rolled her eyes at the mess, but she laughed as well when Mickey started acting up and joking around.

She started chatting about their TARDIS adventures with Sherlock piping up and adding in his own anecdotes, causing Mickey to groan. John checked in with everybody, kissed Sherlock, and talked a little bit before returning to the Doctor's room. Then Molly was free to come out and chat with everybody.

"His name is Jim, lovely man." Molly told Mickey. "Met him in Cardiff after that—Riftquake, I suppose you could call it? Anyway, great bloke, very considerate and modest."

"That's nice. What does he do?" Mickey asked.

Molly shrugged. "He doesn't talk much about himself. General stuff, I suppose. I think he mentioned something about being a contractor? Anyway, he's great, love him." She blushed.

"Do I hear wedding bells ringing?" Sherlock asked.

"Shut up." Molly laughed, punching him lightly on the arm.

Christmas music was playing loudly on the radio and Sherlock shook his head, annoyed with that sort of drivel. But one song kept playing over and over again and Sherlock suddenly found himself humming along, memorizing the lyrics and melody.

"When I woke up today and the world seemed a restless place, it could have been that way for me." Sherlock half sang in a low voice.

"Hey, we need some decorations in here!" Mickey said at one point. "There's a midnight Christmas market down the road. Anyone want to come with me, get a tree and some decorations?"

Rose hesitated, but finally she said, "All right, I'll join you."

"Me, too." Sherlock said, jumping up from his seat.

He was itching to get out of the flat and stroll around for a bit. It was starting to get stuffy, noisy, and annoying with so many people here. He was starting to get bored and wanted to explore for a bit, maybe travel once more. Of course, the Doctor was knocked out, so that was out of the question for now.

"Anthea, would you be so kind?" Mycroft asked, looking up from where he was snogging Lestrade.

Anthea rolled her eyes, but said, "All right, boss, I'll join them."

"Good. Pick out a good Christmas tree, the best!" Mycroft shouted after her before he returned to snogging Lestrade.

Ms. Hudson and Jackie added their own demands and requests to Rose, Mickey, Sherlock and Anthea as Molly and John waved good-bye and blew kisses from their post by the Doctor's bedside. Sherlock waved good-bye and blew a kiss back to John as well as he left with the others.

They went out onto the streets, Rose, Mickey, and Sherlock chatting with each other while Anthea mostly texted and added in a few candid, but bored remarks of her own. They reached the midnight Christmas marketplace and split apart, Sherlock browsing decorations, Anthea examining the Christmas trees, and Rose and Mickey strolling together, listening to the band and chatting.

Suddenly, the band turned murderous and started firing and blasting into the crowd. That really woke Sherlock and Anthea right up and they rushed around, reuniting with Rose and Mickey as they called on Mycroft and Lestrade and told them what was going on while evacuating the scene in a taxi.

Mycroft and Lestrade got to work, calling on emergency response teams to convene on the scene as the others nervously watched and listened to what was going on. John called Sherlock to check up on him and Jackie got a call from her friend Bev, whom she had to reassure that everything was all right before hanging up to call Rose.

Suddenly the doorbell rang and they nervously looked up as John went to answer the door, prepared for anything to jump out at him. Instead, all he found was a Christmas tree left on their doorstep.

"Hello?" John asked, looking around the hallway outside.

"John, what is it?" Sherlock asked over the mobile.

"It's a Christmas tree." John said, examining the tree, which looked and felt like it was made of hard, sharp material. "Did any of you send-"

"No, definitely not." Anthea said, leaning over toward Sherlock inside the taxi cab, hoping she would be heard over the mobile. "I didn't get the chance to purchase and send out a Christmas tree before we were attacked."

"John, do not trust the Christmas tree. It could be from anyone or anything." Sherlock urged.

"I can't believe we're getting paranoid over a Christmas tree." Mickey said. "This is crazy."

"But it makes perfect sense. Those people or aliens disguised themselves as a Santa Clause band. What could be more inconspicuous than a Christmas tree this time of year?" Rose said, worried they were coming after the Doctor.

Back at Jackie's flat, John quickly retreated from the Christmas tree and shut the front door. "It could be a trap." He warned the others inside.

Suddenly, there was a rumbling, whirring sound from outside, and something was pounding on the front door. "Definitely a trap!" John cried out, trying to bar the door as the others panicked, trying to find shelter.

"No kidding." Mycroft said.

Lestrade and Mycroft called for help on their mobiles, Jackie and Ms. Hudson started to shove furniture around to help John bar the door, as Molly nervously stuck to her post by the Doctor's bedside. Now the tree was ripping through the front door and the furniture in the way.

"Oh, no, it's ruining everything!" Jackie cried out.

"Stand clear!" Lestrade said, getting out his gun.

"Wait a minute!" John cried, trying to get Lestrade to lower his gun. "What if the bullet ricochets? That thing is solidly built like armor, look how it ripped through the door!"

"Oh, bollocks." Lestrade muttered, lowering his weapon.

"Nice try." Mycroft told his lover.

Now they were trying to bash and knock out the Christmas tree advancing towards them as Rose, Sherlock, Mickey and Anthea returned. The quartet managed to shove their way into the flat and avoid the Christmas tree, slipping past it to join the others.

They tried to keep the Christmas tree out of the Doctor's room, knowing he was its ultimate target. But the Christmas tree kept advancing, forcing them all to pile into the Doctor's room, surrounding the bed to protect him.

"Well, this is an ignominious end." Mycroft muttered. "Slashed to death by a Christmas tree."

"How are we supposed to stop this thing?!" Ms. Hudson cried, afraid.

"We need the Doctor!" Sherlock shouted.

Suddenly, Rose leaned over to the Doctor, placed the sonic screwdriver in his hands, pleaded for help and he woke right up. He blasted the Christmas tree with a sonic vibration from his screwdriver, knocking out its remote control.

"I can't believe that little device worked and my gun wouldn't have!" Lestrade said.

"Not everything is solved by violence." Mycroft murmured. "Sometimes love and careful attention is required."

"We could have used the sonic screwdriver to turn that thing off?" John asked. "Why didn't we think of that before?"

"Blast it, this is exactly why I need a sonic screwdriver of my own!" Sherlock cried. "I could have deactivated it if-"

"No." The Doctor said.

Muttering about remote control, the Doctor got out of bed and dressed in a bathrobe. The others, bewildered and stunned by what had just happened, followed him out of the flat and onto the balcony corridor overlooking the courtyard below.

The Santa Claus band was down there and the Doctor aimed his sonic screwdriver at them. They backed off and were beamed away, probably back to whatever spaceship they came from.

"What was that?" John asked.

"Another reason why I could have used a sonic screwdriver of my own!" Sherlock cried.

"For the last time, Sherlock-" The Doctor said, turning to him and wincing.

The Doctor collapsed in pain and the others rushed forward to catch him. He explained that the Santa Claus band were just pilot fish trying to eliminate the Doctor's defenses, his friends, to procure him and his regeneration energy.

"Thanks, by the way, for trying to protect me." The Doctor managed to say.

"No problem." John told him.

"It was indeed a major hassle." Anthea muttered.

"Thank you for the brutal honesty." Lestrade said, rolling his eyes.

Then the Doctor cried out that he needed something, and suddenly everyone started clamoring out, calling out suggestions.

Sherlock rolled his eyes. "It's probably something silly and mundane like tea."

"Tea!" The Doctor cried, startling everyone before he passed out.

The others paused, considering the suggestion, before they quickly grabbed the Doctor and dragged him back into Jackie's flat and the bedroom where he was before. Then they started a frantic search through Jackie's cupboards and the bags that Ms. Hudson had brought over, searching for any remnants of tea.

"I think we drank it all!" Ms. Hudson cried, staring into the bottom of the tea pot. "Oh, I knew I should have brought more. But I thought-"

"It's all right, Ms. Hudson, we'll get some." Molly said, turning to the others. "There must be some 24-hour shop that's still open somewhere."

After a quick search on their mobiles, Sherlock, Mycroft, and Anthea came up with the closest location of a 24-hour shop that was still open on Christmas Eve. Anthea, Mycroft, and Lestrade ran out to get the tea—Anthea to purchase the tea, Mycroft to clear any possible obstructions, and Lestrade to serve as security in case they came across any more Santa Clauses.

"Thank goodness we live in a city like London with such modern conveniences." Ms. Hudson said.

John and Molly checked on the Doctor again to make sure he hadn't been too damaged by his excursion. Sherlock and Rose ran down to the TARDIS to fetch some clothes, personal belongings, and John's gun in case they needed to defend the Doctor again.

When they got back to Jackie's flat and Sherlock delivered John's clothes and weapons to him, he inched over toward the Doctor and the sonic screwdriver. John watched Sherlock, aware of what he was up to.

"Are you sure the Doctor would like you to take his sonic screwdriver away from him?" John asked.

"It can't hurt, right?" Sherlock asked. "I mean, I may only need to borrow it from him for just a little while until he wakes up again."

"Which could be a very short while if they come back with the tea soon." John said. "You don't need the sonic screwdriver right now."

"All right, fine." Sherlock huffed.

Mickey did some research on pilot fish while Jackie turned on the news, watching it along with Ms. Hudson as footage from the Mars probe Guinevere One was transmitted back to Earth. And then alien faces appeared on the screen, startling everybody watching.

"Oh god, this can't be a coincidence, right?" Rose said, glancing over at Sherlock.

"We've got to get access to that feed from Mars." Sherlock said, glancing over at Mickey. "Mickey, you still have my hacking software?"

"Yep, stored on my laptop." Mickey said, and he quickly got them access to the Mars transmission feed.

Sherlock soon got a phone call from Mycroft. "Are you seeing what's going on?" Mycroft asked.

"Yes, we have eyes and ears on everything currently happening." Sherlock said. "How is it with you and Harriet Jones?"

"Anthea has us on a conference call with her. I've told her some of what's going on with us and the Doctor." Mycroft said.

"Hello, Sherlock!" Harriet Jones's voice could faintly be heard on Anthea's other line. "How is the Doctor?"

"Currently still out, but once we get some tea in him, he might be better!" Sherlock shouted back with Mycroft relaying the message in case Harriet Jones hadn't heard.

"Shh! There's something going on." Rose told Sherlock as she and the others watched the transmission feed on Mickey's laptop.
