A big small secret

part 1: Protective detective

Dating a world's famous detective with super inhuman deduction skills could be exhausting at times. It was hard keeping secrets from him, even pleasant surprises. You tried to throw him a surprise birthday party once and a minute before you walked him in and everyone was supposed to jump out with cake and presents, he told you in detail what he was gonna find in the room, and that he won't participate and act surprised. Needless to say, everyone was disappointed. 

Sometimes it felt like he was reading your mind and knowing things before you even did. It bothered you that he would never let you know anything better than him. 

So when you first started dating, you agreed that when it comes to personal matters, he would try to keep it down a notch and let you figure out things on your own. 

And that's why this discovery was killing him. 

You were pregnant. 

He was 99,9% sure of it. Naturally the most logical thing would be to tell you. But he knew you for a long time. He knew this is something you would want to figure out only on your own, without anybody's help or conclusions. You'd hate knowing he discovered something so intimate and important before you. 

But knowing it was killing him. He knew he had to protect you and at the same time act no different than usual so that you wouldn't suspect anything. He was hoping with all his might that you'll figure it out soon cause, considering the nature of his work, he knew keeping you safe will be very hard. 

- Sherlock, come on, I always go with you when we have to act undercover. You know I'm very good at blending in.  

- I do know that Y/N but this time I don't need you to. It's a small case, really, nothing of great importance. 

John and Lestrade, who happened to be in the room at the moment, gave each other a weird look. And you made a grimace at Sherlock. 

- Small case? You've been planning this for two weeks with all police forces and your brother, and now you want me to believe it's a small  case? Sherlock, what's the matter with you?

- I think - he began but, as per usual when found in an awkward situation, he started confusingly stuttering - I think - I just think that we don't need, you know, maybe someone can go instead. 

- Who, Mary? 

- Yes, why not? - he said quickly, holding onto that answer like a straw. 

You were still confused and now so was John. 

- Sherlock - he confronted his friend - Mary is waiting for us there, remember? And we agreed we'd drive Y/N with us, what is the problem now? 

Sherlock turned around the room. Everyone was looking at him with strange expressions on their faces. Bugger. He sighed. He couldn't get you out of this one. 

- No, no problem at all. Come on Y/N, time to go. 

And with that he made a tiny turn and walked out the door and down the stairs. You exchanged weird looks with Lestrade while John just shrug his shoulders. It was classic Sherlock. Not making sense. 

During the entire drive Sherlock was thinking of all ways to make you figure it out without actually telling you. His super smart mind couldn't understand how you didn't figure it out yet. You disliked the salted sardines you ate two days ago and you always love them so much. You even threw up after eating them and you still thought it was a "stomach bug" and it "will pass". Your body temperature was 2 degrees higher than usual and you were getting tired 15% more often than before. To him it was all super logical. To you, however, it was a normal Wednesday.
