Previously on „Sherlock"
Sherlock woke up to reality a bit confused, so he looked around to return to the situation he had been in before. As he noticed John on his left he decided to make a funny reference to let him know everything was fine without having to have a huge discussion.
„Miss me?", he asked and couldn't help but smile when he saw his John again... he thought he had lost him! This was relief.
"Sherlock, you're alright?"
John had leaned over to him, his eyes were full of worry. Of course he was worried! Sherlock looked terribly ill.
"Yes, of course I am. Why wouldn't I be?"
It was Mary to reply. Sherlock barely even listened. His thoughts were stuck on John and he was still in his own world somehow and had to concentrate hard to handle reality. Mary wanted... to take him to hospital.
"Hm, no time. I have to go to Baker Street now that Moriarty's back."
That was the clearest thought he could make. Actions were necessary now. So he got up, but walking was still hard to manage.
"I almost hope he is", Mycroft stood in the way, "If it saves you from this."
He lifted the list of drugs Sherlock had taken. It was more of an accusation, although Mycroft would have actually been glad about anything that could keep his little brother from a relapse.
"No need for that now", Sherlock ripped the paper to pieces, "I have the real thing. I've got work to do."
"Sherlock... promise me?", Mycroft insisted, almost begged, letting through a bit of caring in his voice and look. Sherlock had no idea how to react to that. Caring was not an advantage. And suddenly Mycroft broke his own rule? Sherlock had forgotten how emotions looked on his brother. He was confused and a bit tended to give in. But no. He had to shut people out. John was a risk already, but with him the emotions were so strong that he had given up the fight. Then he realized that it was Mycroft who had even brought him to this situation, to losing John, leaving home. What a great deal he had made with the government.
"What are you still doing here? Shouldn't you be off getting me a pardon or something? Like a proper big brother?"
So he rushed out of the plane, Mary following him, John trying to. But Mycroft held him back.
"Doctor Watson... look after him... please?"
Mycroft was very well aware of the impact John had on Sherlock. And although he would have preferred to do it on his own, this was the only option to keep Sherlock safe.
John just nodded, then he went outside the plane. He simply had to be with Sherlock now.
Mycroft stayed alone, picking up the pieces of the paper, just like he had picked up the pieces of his fragile little brother on his worst day, during his darkest times. Memories tortured him. And the fear that they'd happen all over again. Redbeard...
"Sherlock, hang on", John ran after his tall friend, "Explain. Moriarty's alive then."
"I never said he was alive, I said he was back."
They stopped in front of the car.
"So he's dead", Mary assumed.
"Of course he's dead, he blew his own brain out, no one survives that. I just went to the trouble of an overdose to prove that."
Hopefully John wouldn't react as he had feared... hopefully he would stay at his side... Sherlock couldn't stand John being mad at him... or even worse – losing him. And hopefully he wouldn't find out that he had been the reason Sherlock had to anaesthetise himself...
"Moriarty is dead, no question", he went on after a short look at Mary, "More imporantly: I know exactly what he's going to do next."
Sherlock said the last sentence explicitly to John and gave him a little smile. After the comment about his coat collar etc. Sherlock knew that John loved it when he was being mysterious. So he simply went into the car, the other ones following him.
The fall was over. The game was on.
