you were the kid of a king and queen but that was before they were killed in one of Moriarty's sick games so it was just you,the royalty of London but in the night time you were a crime stopping delinquent dressing up like a commoner an became very skilled with weapons' and athletic/self-defense stuff

years later it was two days before your 20'th birthday and little did you know Moriarty had something big planned for you after several years and sherlock went to London to warn and save you

so today it was early morning after another on of your patrols saving people the butler came to wake you up as the guard notified the butler that sherlock and Watson was here
