Strengths: Sally has an iron will: she won’t back down from a man (Sherlock) she considers to be a dangerous psychopath, and even goes so far as to casually taunt him. When it seems that Sherlock has committed a serious crime, she manages to convince her boss to take him in for questioning, even though he considers Sherlock a friend. She is a skilled policewoman, as evidenced by the fact that she’s a sergeant - and seemingly her boss’s second-in-command - at around age thirty, and though she was ultimately incorrect, she made several sound deductions about an intricate case based on the information presented in The Reichenbach Fall. Sally is determined to uphold the law, but she also cares about other people as human beings: she shows concern for the safety and well-being of others, though she takes care to remain detached, probably for professional reasons. She also seems deeply sympathetic and stricken when she comes across a pair of sick, abducted children. She’s good at reading people she doesn’t know very well: in The Reichenbach Fall, when someone taunts John, Sally seems to automatically understand that the remark had been past John’s limit, and looks to John in shocked understanding that he is about to overreact.
