It's a pretty open and flimsy role play in my view right now, but I'd kind of like to see some John+Molly AND Jim+Molly happening. Kind of where she loves John, and Jim likes her. It could go in whatever direction also. Depends on you guys. We could also make it so that Sherlock and John don't know about her dark side until they solve a case and she's nestled at the bottom or something, but I'd like to throw ideas out with other role players who are interested.
Give me some thoughts, and claim a character! (I'm Molly, by the way, in case that wasn't obvious enough).
