role reversal - I got you some coffee

I'm doing a thing on my tumblr atm where you can send me a 1-3 sentence fic (word limit: 160) about a fandom I'm active in, and I'll attempt to draw something for it. 

this is 's prompt fic:

doctor!Sherlock/consulting detective!Molly (I FOUND THAT I REALLY LIKE SWAPPING THEIR ROLES??): Sherlock was used to it by now, being called in the middle of the night to have her demand that he come help her in the morgue for a few hours. It was almost routine for them; he would arrive, already alert and curious, and Molly would be waiting impatiently with two cups of coffee in her hands. They would often work past dawn and, when done, parted with the unspoken promise of meeting again soon.
