Sherlock:
As soon as work was finished, you made a mad- dash to your flat. You brush your hair and put it in a nice braid, then you brush your teeth to get your lunch off of them.

You pull off your work clothes, and put on a red dress that accentuates your curves. Then, you put on some sleek black stilettos and spray a modest amount of perfume.

You check yourself in the mirror. Perfecto, you think. You grab your clutch and breeze out of your humble flat, seeing a shiny black car waiting just outside. The door opens and a man in a black three- piece suit and an umbrella is already in there.

"Miss (L/N), I am here to take you on your date with my brother," the man says. You climb into the car and sit next to the man. The ride is short and silent.

When the car stops, you get out and go into Sherlock's flat to see Sherlock there, fidgeting and warm food on the table. He smiles slightly, and the date begins.

By the end of the night, he walks you to your flat and gives your hand a kiss. "Goodnight," he says. You return the message and head inside, internally screaming.

Mycroft:
You close up the bakery and tuck the keys in your pocket.

Today's the day of your date with Mycroft!

Smiling happily, you hail a cab. Once the cabbie sets off in the direction of your flat, you compile a metal list of what you're going to wear and how you'll do your makeup.

The cab stops and you jump out, throwing cash at the cabbie, and running to the door of your flat. You put your key in the hole and unlock your door. Then, you quickly pull your work uniform off and hop in the shower to rid yourself of sweat, flour, sugar, and chocolate that had managed to splatter on you whilst you worked.

You step out of the shower and dry off. Then, you put on a wavy navy dress that falls just above your knees, and some shiny, red flats. You put on a light coat of makeup and dry your hair. You brush it out and curl it. 

You check the time.  6:45. 

The doorbell rings and you open it to Mycroft. He takes you to Giovanni's as promised. The date begins.

When you get back to your flat, you open the door and wave goodbye to Mycroft as he leaves. He waves in return, becoming officially out of sight. 

Moriarty:

Jim takes your hand and pulls you to a random person's house. You murder them and their whole family. The rest of the date is spent running from police.

(A/N- I got tired of writing everything out.)

John:

He takes you to a diner. You dress in jeans and a nice blouse with some flats.

Greg:

You dressed in jeans and a t-shirt. You go to a pub. They had really good burgers. Of course, both of your brothers crashed the date, so you and Greg left and went somewhere else.
