Summary: After the wedding, Sherlock is trying to put his mind at rest.
The battle is over. Sherlock removes his morning suit. Puts it back in the garment bag. Places the bag in his wardrobe. Closes the door of the wardrobe then the door of his bedroom.
Sitting in the leather chair that was in front of John's, he watches carefully around him. Why everything can look exactly the same when the world as he knows it just crumbled under his feet? The wedding decorations, invitations and other samples are still scattered around the living room. He should put that away. Put everything related to this day away. The day where he had to be the bravest version of himself. The day he gave his best friend, the love of his life, to someone else...
Lost in is thought he didn't realize he wasn't alone anymore before a soft "Sherlock" was spoken. Opening his eyes the detective looks at his brother.
"What are you doing here?" Sherlock turns to the unlit fireplace wanting to avoid the scrutiny of Mycroft's gaze.
"Do I need a reason to talk to you brother dear?" The older man says. After a pause he added "The wedding was satisfactory? I heard that you caught a killer... I am now sorry that I refused the invitation" Mycroft added with a little laugh.
"I'm alright, there's no need to babysit me. As you told me when I returned, why should I expect John to just sit in his chair and wait for me in case I wasn't truly dead? I am not that selfish and I am really happy for my friend to have found love and happiness."
Mycroft looks at his little brother with eyes full of compassion and understanding. After a quick survey of the room he comments, "I can have someone get rid of all that if you want?" waving his hands towards the napkins and the other wedding stuffs.
"No it's ok, I'll talk with Mary after the honeymoon to be certain that she doesn't want to keep anything then I will throw it all away. It can stay here for 2 weeks, I don't mind. Now. Just go please. I want to be alone... Don't worry it's not a danger night."
"You know that I worry about you constantly, it's one of my few hobbies. I will send someone right away to at least store everything somewhere out of sight. Please inform John to contact me at his return."
"Yes, yes I will" the detective says already leaving for his Mind Palace, "I just need some alone time after the last few weeks and everything will be fine. I could do with a little clean-up of my Mind Palace with all of those stupid serviette videos!"
"Ok. But don't forget that I am always there for you and will always be."
"Stop being so dramatic it doesn't suit you Mycroft. Bye and say hello to the Queen." he replied absentminded while his brother left the flat to asks Anthea to clean up the apartment of everything linked to the wedding.
Once more alone, Sherlock put his hands under his chin, closes his eyes and open the door of his mind. Once more into the breach as that old Shakespeare said... Archives of most violent criminals. Keep. List of all the boroughs, streets and alleyways of London. Keep. Redbeard is definitively staying. Let's keep the door of the 2 years chasing Moriarty's gang closed for now. There. John's room. Everything happens so quickly since his return that he lazily put Mary's stuff in his blogger's room. He opens the door slowly, not certain of what was inside. John is always so present in his mind that he almost never needs to check details in his Palace. Because if Sherlock's brain is a computer, then John's details are in the RAM and not the hard drive that is his Mind Palace!
The first thing that appears to him inside the doctor room was Mary. Mary with a confident, nearly cocky smile. Like a permanent proof that she won. He quickly dismisses her in search of wedding planning stuffs but keeps seeing Mary. She's everywhere, like if she wants to keep him away from her husband. He's the master of his Mind Palace! Sherlock virtually takes Mary's hand and pushes her into oblivion not wanting any part of her in his head. But the virtual Mary is as stubborn as the real one and she takes John's arm, not wanting to let go. With a devious smile, she pushes him with her in the deep of Sherlock's oubliette. Putting her John safely away from Sherlock, forever trapped between Madonna and the Solar System.
Sherlock wakes from his self induced trance a few hours later with a deep feeling of uneasiness. Like if something was missing, like an unsolved problem.
