Sherlock deducing John’s lips.
Like, he deduced John’s got a new toothbrush because he noticed there is something different about his lips. John’s lips. Sherlock has beenpining forstaring at those lips before.Yes. The way John’s lips are lovingly traced by the deduction. The way John’s lips look here…because Sherlock is looking at them? The bite-able quality of John’s chin. And the context of this scene.
I love all of you.
