You worked closely with Sherlock and John. Helping them every once in a while with small missions and such. In this you’d seen Jim Moriarty a handful of times. Never spoken to him. And though he did acknowledge you every once in a while you never expected him to be oddly nice to you— As he has been terrorizing Sherlock and John and leaving you be. You mention it to them.

“Oh looks like someone has a soft spot” John said sarcastically implying Moriarty had a soft spot for you.
