While they'd been talking, she'd been sitting back and trying to figure out what the markings could mean. Why the heck were they on the roof of the mouth anyway? Sherlock probably knew. That had to be why he'd been grinning, the markings. He must've figured them out. Biting her lip, she tuned into what Sherlock was saying, blinking and taking a moment to get the gist of the conversation again. Giving up, she turned fully to him and asked quietly, in case it was some sort of big secret somehow, "What are the markings in the mouth?" She had no idea what they were meant to be and didn't hold any hope that she'd ever figure it out either.
