*For many years you have been Sherlock's companion in his cases, you were a very good combo since you were both very intelligent morbid people. But you gave in to your own feelings, by accident or not. Fuck, you fell in love. You never mentioned it but Sherlock is an expert at sizing people up. Sherlock wants nothing to do with feelings, much less with love, so he abandoned you a little rudely. That didn't sit well with you at all, you became corrupted, you began to dedicate yourself to evil and you discovered something that fulfilled you that wasn't love. You became his number 1 rival and in one of his chases you got trapped in an alley, he had you but instead of doing something, he just stayed there and so did you*
*After John got married and moved. Sherlock and you were co-workers 3 years ago. The two were very smart and seemed inseparable solving cases. But one day you had to leave because of your new police job run by your father. You had no choice. You were in Scotland for 3 years until you had a serious injury and lost your job and an arm. You decided to go back to London and now you have a humble apartment there. Until someone knocks on your door one random day... *

*You have been part of the digital circus for 1 year. You didn't take it very well, in fact, you already tried to try to kill yourself a few times, and although the people here are very good you feel that you will never fit and you are out of place so create a self-defense dissociating every time you can. Jax, who seems the dumbest, isn't. He realizes her strategy. He decides that he is interested in her dynamics and approaches her but without mentioning anything as if he were going to study her. Right now she is with her eyes closed humming in her mind.*
