The instances of John encountering Sher-cat were becoming more frequent. Not that it was an everyday event but it happened at least once a week and at most three times. The length of the episodes was never a constant but John didn't mind.
John figured that Sherlock liked pretending to be a cat because he did things in that mentality that he wouldn't do otherwise. For example Sherlock always invaded others space but somehow he kept people out of his own. But as Sher-cat he went down to basic instinct. But John was the only one he chose to respond to. There was also the fact that it was quiet when Sherlock was being a cat and though it wasn't how most flatmates spent time together it was kind of a bonding time.
For Sherlock have the Sher-cat persona brought home just how important John had become. He had always been a verbose person even as a child. Words were his weapon and his shield. But when that was removed he realized just how well John knew him. With a look he could convey anything and John would understand. Not because he was fluent in the language of observation like Sherlock but because he knew Sherlock well enough to interpret his expressions.
A roll of eyes and a grin received a reply of 'I know I'm an idiot we can't all be as smart as you.' This was cheerily said because the grin meant 'but I still like you anyway'.
A twitch of the hand and rapidly moving eyes received a put upon utterance of 'if I play cluedo with you will the wall be safe?'
It wasn't just that his expressions could be read it was also like John knew what he needed and not just on cases. Without John he would most likely not eat until he passed out, (that had been the case before, not that he had told John that but he somehow suspected that the Doctor knew it anyway) he wouldn't drink or sleep in healthy quantities either.
Sher-cat altered that dynamic even more because as a cat Sherlock let John take care of him more and he was actually a bit more openly affectionate. John found it humorous that by acting like a cat Sherlock was slowly becoming more human.
The fact that Sherlock was practically feline in his actions anyway made him even more interesting when he choose to be Sher-cat.
The third instance of Sher-cat was one that John would never forget because it saved both of their lives. They had been captured for the fourth time that week. This time it was by a person that even John wouldn't hesitate to call an idiot. The man had dropped out of school at twelve to pursue a full-time career of petty crimes. The man had caught them purely by accident and now was holding them at gunpoint.
"Where is it?" the man growled in an irritating voice that gave John an instant headache.
"Sherlock what is he talking about?" John asked.
"Most likely something that I discovered in a case that I had before I met you."
"Shut up!" the man screamed in irritation because the two of them didn't seem scared despite the fact that he was the one with the gun in his hand.
After that neither of them spoke and that was driving the man, who was named Bob of all thing, bonkers. So he moved them to the basement of the building so that he wouldn't give in to the temptation to shoot them before he got his answer.
When Bob came back he was even more trigger happy than before. John was sitting on the floor petting Sher-cat.
John had never mentioned Sher-cat on his blog and the only people that knew were some of the Yarders, who for reasons not to be named had talked about it to no one. So there was no reason that this idiot would see through the plan.
John's hand never stopped petting Sher-cat but his eyes pleaded with his captor. "You have to help me. He really has lost it. He thinks he's a cat."
Bob stood still for a moment before aiming the gun at John daring him to move as he kicked Sherlock. Sher-cat hissed and swiped angrily at the man. When Bob was distracted John moved quickly taking the gun and turning it on its owner.
A/n Saved by Sher-cat what could possibly happen next?
I'll tell you this it will be kinda fluffy. ^_^
