Tiredness has started to creep in at the edges -- but he has a case to finish and he won’t rest until he does so. The coffee at the precinct is absolutely vile and though he dislikes parting with cash with inadvertently supports evil conglomerates... desperate times call for desperate measures, and so he’s in like at STARBUCKS or all places. He knows what he wants... normal coffee, black, which is why he’s ( impatiently ) lifting his eyes to the ceiling and bouncing on his heels as he waits. He glances around, looks back to the front before doing a double take. He recognises her. That’s... no, surely not.
After tapping the floor with his foot for the best part of a minute he turns and, impulsively, leaves the line and steps to where she is about three people behind him. He didn’t notice that she was with a man, though, or else he wouldn't have come over. Too late now. He stops near her and parts his lips, wondering what to say,
“uhm -- Crystal?” he’s quiet for a moment, “it’s Sherlock.”
