The Sign of Three (Sherlock x Female!Reader)

Chapter 3: Best Man Speech

You were walking around the reception area, just walking and saying hi to people. You walk up to the table where Lestrade, Molly and Tom are sitting at so you decide to talk with them for awhile.

"Hey, (y/n)." Lestrade greeted.

"Hello, everyone." You said.

"You look lovely, (y/n)." Molly said.

"Thank you." You said. "So, everyone doing alright? Having fun?"

"Oh, yeah, loads." Lestrade said, in a sarcastic tone. You laugh as you four just talk about random stuff.

"I can't believe John is a married man." You said.

"I know, right?" Molly said.

"So, (y/n)....when can we expect a happy announcement from you and Sherlock?" Lestrade asked and you choked on your drink. "Oh, goodness!" Lestrade said as he pats your back and Molly hands you a napkin.

"Sorry....didn't mean to spring that question on you." Lestrade said as you clean your mouth with the napkin.

"It's okay....it's just....I didn't expect that question." You said.

"Well, it's just....you and him seem closer since he returned...so I just didn't know if...." Lestrade said but you shake your head.

"I'm not sure if Sherlock is the marrying type to be honest, Lestrade." You said.

"Well...he might....I mean he didn't use to be the relationship type of guy until he met you." Lestrade said.

You look down at the table and think this over. 'He's right.....Sherlock did tell you when you first met him that relationships weren't his thing and look at you two now! Hmmm, if that's true, does Sherlock want to get married?' You look over across the room and see Sherlock pacing back and forth at the back of the room, talking on his phone; and from the look on his face, he was obviously talking to Mycroft.
You think this over for awhile until they announced the start of the feast and you head towards the top table and take your seat.

After everybody eats their way through all three courses and drink a lot of champagne, the Master of Ceremonies taps a spoon against a champagne glass to get everyone's attention.

"Pray silence for the best man." He said and the guest start to applause and cheer as Sherlock rises to his feet.

"Ladies and gentlemen, family and friends....and....erm....others." Sherlock said and he stops and blinks as there is a n awkward pause. "Er....w....a-a-also..." Sherlock stammers as you sit back a little, looking concerned.

FLASHBACK

​​​​​You and Lestrade walk into Molly's lab at Bart's. "Greg. (Y/N)." Molly greeted. "Molly." You and Lestrade said. "I just had a thought." Molly said as she holds a large metal bowl in front of her and Lestrade looks into it. "Is that a brain?!" He asked.

"What if John asked Sherlock to be his best man?" Molly asked, ignoring Lestrade, looking at you.

"Well, he will, won't he? He's bound to." You said.

"Exactly." Molly said.

"So?" Lestrade asked and the you realize what she's getting at.

"He'll have to make a speech in front of people. There'll be actual people there, actually listening." You said and Molly nods.

"Well, what's the worst that could happen?" Lestrade asked, tentatively.

"Helen Louise probably wondered the same." Molly replied. "Helen Louise?" Lestrade asked and Molly pointedly looks down at the brain in her bowl.
