They seemed to draw too much attention to it for it to be of no importance.

Overall a great episode. They have done a good job of showing Sherlock's gradual humanization (I doubt if he would have apologised to Molly at the start of last season). I enjoyed that this episode showed that Sherlock can be out-thought & played (and not just by one person), it's an important aspect for how this is going to end.

Roll on next week.
