It had been 2 years since Sherlock had jumped off that building and ended his life. That was due to the little Moriarty incident that had happened. Sherlock, had been your parent, your caretake for almost your whole life. This had been devastating to you. John had ended up moving out of 221 Baker St. and he took you with him. You had left everything behind. Mrs. Hudson the flats caretaker, your old flat, old room and everything else. Basically started completely new.
Now things were better for you and you were trying to live life. All your life you had been homeschooled but with the new changes, you had to go to a public school. Getting bullied a lot because of your situation was a problem. John had met a woman named Mary and they grew really close. He also grew a rather unattractive mustache.
Tonight you were alone at home. John and Mary had gone out. He was planning to propose! So you just had to wait patiently for the news when he came back.
Soon he came back home with Mary, you immediately went to ask him. However, he looked pissed. Mary looked fine however. Little did you know it was cause Sherlock had revealed himself as alive to them.
