"Oh, you MUST be kidding me, Lestrade!" Sherlock chased after the quickly departing Inspector.
"Look, Sherlock, it's a charity thing. Every one of the Scotland Yard is signed up and so are all the employees of the hospital John works at. It's only fair that you are involved as well-"
"But I don't even work for you! OR the hospital! I'm in no way connected! I shouldn't have to-"
"It's too late, Sherlock! Your name's already on the list. You are going to help out with the haunted house, no matter what excuse you give." He shot a pleading look at John. He hadn't wanted to bring John into their scuffling-last time he had, Sherlock had held a grudge against his flatmate for a whole week- but only the army doctor could get the man to shut up.
"He's right, Sherlock. Besides, it'll be fun."
Sherlock glared down at his companion.
"I already have plans," he muttered bitterly.
"Oh, please, doing what? Taking candy from children?"
"Stay out of it, Anderson, it's none of your business." The detective looked the sour man up and down who had seemingly appeared out of nowhere. "Does either Sally or your wife know how many other women you're sleeping with? And speaking of Sally, when will she realize that she could do so much better than you?"
"You-"
"Alright, alright, that's enough!" Lestrade interjected before things got worse.
"Anderson, get back to work. You have better things to be doing than telling off someone twice as clever as you,"
Anderson scoffed and stomped off while Sherlock muttered something about being ten-times as clever.
The Inspector turned back to Sherlock.
"Now, you can either be a vampire or a werewolf."
"NO! NononononoNO!" Sherlock threw up his arms in exasperation.
"Fine we'll choose for you." said Lestrade cooly. He looked at John. "Well he's pale enough to be a vampire isn't he?"
John nodded, trying to keep from smiling.
"Jaaaaaaaaahhhwn!" Sherlock whined.
"Don't worry, Sherlock, there will be plenty of blood everywhere-" John laughed.
"And what will YOU be doing, Doctor?" Sherlock shot back at his friend.
"I'm a mad scientist," John said proudly. He snapped on the goggles he had been holding in his hands and twisted his face into a maniacal grin.
"You look more like a depraved insect- But John, how can you go along with this?"
The doctor shrugged.
"I like the idea of doing something nice for the kids. They'll love it."
"And be scared half to death!" Lestrade joined in, grinning.
Sherlock smirked and then sauntered away in a sassy fashion.
"Uh oh, I know that look…" John said. "He's gotten an idea in his head and I can promise you it won't be pretty."
"Well, we'll have to keep a close eye on him then."
Lestrade clapped a hand on John's good shoulder as he turned away to continue organizing the fundraiser.
"Maybe he should be a mad scientist himself," John mused aloud as he followed the lanky detective to the main street.
I don't know yet if I will continue this, because it sorta just happened out of nowhere. If I do though, it'll end up becoming a smutty fic. Hehehe.
