When John Watson introduces his cousin Lily, to Sherlock, Sherlock naturally ignores her. However, Lily is determined not to give up trying to make him like her - taking on cases with them, helping out in any way she can. And when there are finally signs of understanding and possibly even admiration - something else happens that throws it all back where it started. A story told mostly in flashbacks and non-linearly. I only own my character and the plot (I don't even know why I'm writing this disclaimer but here you go).
