"Can't you just pick one?" Sherlock asked as he watched The Doctor sort through the numerous bowties in his chest-of-drawers. He had moved into 221c earlier that day. It had been two weeks since they met and Sherlock hated the timelord slightly less than he had a fortnight ago.
"I have to look cool. Although all bowties are cool, really. You know all about cool, so I'm sure you will agree."
"I have no care for fashion or adhering to it."
"Yes you do, what with your cheekbones and turning up your coat collar."
"What did you just say?" asked John, who had been helping The Doctor move boxes into his new flat.
"Yes, John's said that before too. I really don't know what you want me to do about my cheekbones, though. I can't exactly get them removed."
John laughed, and The Doctor smiled. John and Sherlock were friends, that much was obvious to him- what was his relationship with Sherlock? Maybe something like frenemies.
"So can we have a look in this...box then?" John asked, referring to the TARDIS, which The Doctor was keeping in his flat.
"Of course!" he replied. He loved to show people around the TARDIS.
He opened the door for John, who stared at the insides blankly. "It's...it's bigger on the...on the inside."
The Doctor laughed. "You going to have a look, Sherlock?"
"Boring, mundane pleasantries. Sociopath, remember? Frankly, I couldn't care less about your...TARDIS.
"No, Sherlock, I think you really will want to see this." said John, who was exploring the TARDIS in awe.
Sherlock got up, knowing John wouldn't press him unless this really was something he would want to see. He looked through the doors of the little blue police box. His mouth formed a small 'O', which it hadn't done in a while. Or ever, really. This thing- awe, was it?- he hadn't felt it before. He looked outside of the box. Rectangle. He looked inside. Huge. Cavernous. Round. He ran inside, feeling the walls and spinning around, making sure it wasn't some kind of illusion.
"I think he might be broken...he's never done that before." John said to The Doctor as Sherlock ran towards the controls of the TARDIS.
"That is...amazing. I- how? What...? It's huge."
"TARDIS technology." said The Doctor. "From Gallifrey."
"And...it's a time machine. How does that...it doesn't comprehend. It's illogical. Surely even travelling through time will change the course of it..."
"Well, people assume that time is a strict progression of cause to effect, but actually from a non-linear non-subjective viewpoint, it's more like a big ball of wibbly wobbly timey wimey...stuff."
"Wibbly wobbly..."
"Timey wimey." The Doctor finished.
"Did Sherlock just say wibbly wobbly?" John said, grinning.
"I really think he's broken."
"I'm not broken! All of this is highly illogical...logic is broken."
