"But.. How?" Was all the Doctor could choke out. Sherlock now looked at both The Doctor and the Master, who had been Jim. His eyes rolling back and forth as the men seemed to be having a staring contest.
The Master was debating about whether to tell the Doctor how he came back or let him work it out himself. His idea was made up when the Doctor flicked his eyes over to the TARDIS, he obviously hoped to get it back soon, that would therefore make this a hell of a lot funnier.
"Ok, I have a proposal." The Master broke the steady silence and looked the Doctor dead in the eyes, then moved to Sherlock and looked him dead in the eyes. "You are both fairly smart, so together, you should be able to work out how I came back. Then, and only then, you will get your TARDIS back."
"This really is all a game to you?" Sherlock asked, getting quite angry. "This man has done nothi-" The Doctor cut him off.
"Sherlock, I wouldn't." The Doctor warned.
"What did you do?" Sherlock sighed impatiently, as did the Master, he clearly had better things to be doing.
"Long story, explain later." The Doctor turned swiftly back to the Master and agreed to this game.
"You have two weeks." The Mater stated, he got in the Doctors TARDIS and flew off through the skies.
The Doctor ran to where the TARDIS had dematerialised and scanned the area, his sonic screwdriver stated that he'd gone into the past. The Doctor thought it was useless and ran to grab a taxi, Sherlock and John followed quickly and Sherlock would not forget that the Doctor owed him an explanation.
They found a cab and got in, the car ride was silent for the first 15 minutes, both the Doctor and Sherlock were thinking, and John was, once again, staring out off the window.
"Why are you in such a hurry to get back?" Sherlock asked when the Doctor was tapping his fingers impatiently against the door handle.
"I left my wife and her parents alone on a planet with three suns. Amy and Rory are only young, I'm thinking about whether River can keep them safe." The Doctor said, after a confused look from both the men in the taxi the Doctor decided to give them a little bit then say that he'll tell them later, there was no time for a full-blown explanation now. "River, you know the one in the library that I told you about," The Doctor didn't pause but saw Sherlock nod so decided that he'd kept up "well, recently I met two new people Rory and Amy, a married couple. They didn't like the bunk beds and they wanted a double so I gave them that and then they spent their honey moon in the TARDIS, it wasn't there first night together in the TARDIS but for a bit Rory didn't exist, then he was plastic, then the universe didn't exist, bit complicated. But anyway, they had a baby," The Doctor fidgeted, he was like a 5 year old boy talking about holding hands with a girl "and she was called Melody, but then someone kidnapped her and renamed her River and told her to kill me, then she didn't want to so we went into a alternate universe, the only way that River would kill me was if we got married. Now, yes I probably love her dearly in my future and I love her dearly now but at the time I thought it a bit weird, we'd only been out a couple of times but, as I told you, time goes askew with me and her because her past is my future so we got married and now I left her with her parents on a planet with three suns and River is the only one that knows what to do properly if anything bad happens, and if that fails she has to call the TARDIS, but if I don't have the TARDIS then how can I know if something bad happens?" The Doctor was out of breath and breathing heavily by this point and John's eyes seemed to bulge out of his head. Sherlock sat there silently, he didn't want John to see that he didn't know everything because when the Doctor speeds off again he still had John to look after. "So, that's my life up until now, what have you been up to?" the Doctor asked jokingly.
Sherlock and John looked at each other and said "nothing." together.
"Ok, well, out we get!" Sherlock and John walked out of the cab and payed the driver before following the Doctor up the stairs to 221b Baker Street. "Sherlock, you've dealt with this man before? What do we do?" The Doctor needed his TARDIS and knew Sherlock could help get it back
"Do what he says, work out how he came back."
"Honestly? But that's so boring! I thought you were all about fast paced deductions!" The Doctor fidgeted in his chair.
"Well, what did you do to him to make him so angry?"
"Really long story! He wanted to bring back the Time Lords but I couldn't allow that, the Time War was over and if they came back then it would start again, all that fighting would continue, I couldn't let it happen" Sherlock knew all about the Time War, he'd been good at getting the Doctor to talk about things and knew most things about him. "well, I sent the Time Lords back to the time that they came from. But not without damages. He had to go with them, and I had to change." He looked at the floor
