it's always the shoes....

here's the OC for the dashing , and the description:
She's Johns Cousin on his fathers side so she shares the same last name. Her parents often work away so she lives with John and Sherlock most of the time and sleeps on the sofa in the lounge (feel free to re-word all this!).
She quickly (and strangely) becomes Sherlocks close friend, she teaches him about the universe, he teaches her psychology and he often watches her as she draws.
She makes jam in the kitchen (when Sherlock isn't using it for his experiments) and often bakes.
She is first introduced into the series when John goes out to get the shopping and she arrives at the door, Sherlock has no clue who she is (the first and only person he can't read) but lets her in anyway where she explains she sent a John a letter and they both agreed that she could stay for a while. She gets along well with Molly and constantly pranks Anderson.

there ya go!
