Chapter Text
“Sherlock.”
”Yes, Watson?”
”Mate… what’re you doing with my mug?” John asked his flatmate.
”Experimentation, Watson,” Sherlock explained.
”…right. With my favorite mug? We have like a million others!” John protested.
”We have 7 others, Watson. And why don’t you use one of them?” Sherlock challenged, not even bothering to look up from his work.
”Because it’s my favorite!” Watson all but whined again, making a grab for his mug.
”I wouldn’t do that Watson, unless you’d like chemical burns on your arms to match those of which are already on your leg and side,” the detective said, making John freeze.
”Wh-WHAT? Sherlock!” John sputtered, “what do you have in my mug? My favorite mug?” The ex army doctor demanded.
”Nothing that you would approve of, I assume,” Sherlock said dryly.
”Sherlockkkkkkk,” John groaned, crossing his arms and pouting. His bun bobbled around on his head and he sighed deeply, “and why my favorite mug?”
“Because it was closest,” Sherlock simply told his flatmate.
John looked confused, “mate, I know I don’t know my sexuality but why was my mug in the closet?”
”No, Watson. Closest,” Sherlock repeated, briefly looking up so John could see his lips. John had hearing troubles and tinnitus after the war but frequently refused to admit it. Sherlock decided one battle at a time and was still trying to convince John to take care of his leg, so he accommodated his flatmate without raising suspicion….mostly.
John sighed and rubbed a hand along his face, “ok well- can you maybe not use my favorite mug next time?”
”Oh, then shall I use the Dr Who one?” Sherlock asked honestly.
”nO-!” John said quickly, looking fearful for his mugs.
” ‘Yeah I have tons of internet kids, and?’, how about that mug?” Sherlock asked.
”Thats a present from a fan!”
”The SuperNatural one?”
”Noooooo please don’t hurt my hunters-“
”Gravity Falls? John, you must realize that’s a children’s cartoon!” Sherlock says.
John gasped comically, “NO! Not my mystery twins!”
Sherlock sighed, “then what should I use for my experiments?” The detective asked, almost irritably, as if John was the crazy one for not wanting his mugs used for dangerous experiments.
”uhhhhh science equipment, preferably,” John responded, still a bit worried about his mugs.
”Yes but…” Sherlock trailed off.
”But..?” John prompted.
”But those are boring, Watson,” Sherlock huffed.
John just blinked at his flatmate, “…Jesus- Sherlockkkkk!” He groaned for the second time, “what if we- I dunno. Put stickers on them or something?” He suggested.
Sherlock seemed to perk up a bit at this, “really?”
John just giggled and nodded, smiling, “yeah, course mate. As long as you leave my mugs alone.”
Sherlock smiled gently, “thank you, Watson.”
John nodded again, “no problem,” he said and walked to get a glass and some pop out of the fridge. Just as he put it to his lips, Sherlock called out to John,
”I wouldn’t do that if I were you, Watson.”
John looked at the glass in his hands, which was oddly warm, and frowned.
Then the pop started turning pink and-
“oH SHIT. IT’S GONNA BLOW-!”
