It shouldn't have surprised John, really. After all, Molly Hooper had succeeded in getting James Moriarty to sit down and watch Glee. That alone should have given us an idea as to what she could make one Sherlock Holmes do.
But still, even with that knowledge in mind, John couldn't help the roaring laugh that escaped him once he caught sight of his best friend and former roommate.
Sherlock came out of the bedroom wearing a pirate costume, complete with the eye patch. He also wore a pout that looked as if it could stay as a permanent feature of his face, all the while glaring daggers at John. Well, at least he tried to.
"Shut up, John," he snapped.
"Oh, don't be so grumpy, Sherlock," Molly chided, stepping out of the bedroom also, clad in a pirate dress that matched Sherlock's outfit. "You can relive your childhood dream for a night. I thought you'd be more excited," she added, standing on her toes as she reached out to straighten his pirate hat.
Sherlock groaned. "I should have never let you talk to my brother."
Molly smiled. "I'm glad I did. It proved to be…resourceful." Her smile turned to a grin at the end of her sentence. Oh, yes. She was truly glad she had some talk with the elder Holmes. Much like his younger brother, Mycroft wasn't exactly one to blab. But of course, her talks with him had given her some more insight on her not-boyfriend. For example, his obsession to be a pirate when he was little.
"I don't want to go," Sherlock whined. Molly waved her finger at him.
"Nope. You, Mister, are going to that Halloween party," she said with an air of finality in her tone. It worked, judging from the defeated look on Sherlock's face. His shoulders slumped and he said nothing more.
From his spot in the living room, John was watching the exchange between the two in amusement. For a man who hated sentiment, Sherlock Holmes was definitely whipped. 'She threatened to tamper with my experiments, John!' Sherlock had said, then. 'And she knows just how to do so!' he added (while there was truth to his friends' words, John knew Sherlock was slightly exaggerating). 'I was not!' came Sherlock's rebuttal (but John knew better. After all, Sherlock Holmes was his best friend).
It's not like Molly was one of those women who like to force their partners to follow their every whim. She wasn't a demanding woman. She had received an invitation to a Halloween party thrown at her friend's place a week ago, and since she didn't get to go to parties a lot (what with her work and all), she decided that this once, she would go. Sherlock didn't have to come, but then he had to get himself almost killed (a suspect shot at him; it barely missed his shoulder and ended up grazing his skin), and the next day he shaved Toby's fur for an 'experiment' because he was 'bored.' So Molly thought it would be okay to have her little revenge; give Sherlock a little punishment for almost giving her a heart attack and making poor Toby suffer in the cold weather.
She had batted her eyelashes and sent him her sweet, sweet smiles. And then she had given him some minor threats concerning his ongoing experiments in her lab at St. Bart's, still with a smile playing across her lips. It wasn't a cynical or mischievous smile; it was innocent and warm and that's what made it feel more terrifying to Sherlock.
Sherlock stared at the petite pathologist in front of him as they walked out of the building. Mary Watson was already waiting in her car, parked in front of the flat. John quickly got into the passenger seat. Remembering all the mannerisms Mummy had taught him, Sherlock held the door open for Molly. She looked up and smiled at him, her gratitude shining through her wide, brown eyes. As he looked down at her, Sherlock couldn't help but wonder how the devil could come in such a small, soft, cherry-scented sweet package.
