TRICK OR TREAT, THEN
Sherlock had clearly enjoyed himself.
Mycroft sighed as he finished wiping the chocolate off of Sherlock’s arms. Kids that young, especially kids like him, should not go trick-or-treating. He had pulled from Mycroft’s grasp about halfway and sprinted away, leaving him behind in the crowded streets full of children and adults alike. Mycroft had been too slow to catch him.
He found him with a group of older kids much later, rustling through his bag and smearing chocolates all over his arms. The others looked dumbfounded. Mycroft had promptly yanked Sherlock away and marched him home.
“I’m out of chocolate,” Sherlock complained once Mycroft rinsed the rag. “Stupid chocolate.”
