It´s a boy!

"John!" Excitement.

"John, dear!" Stomping on the staircase.

"John, love!" Ripping the door open.

"Why the fuck are you shouting around the flat, Sherlock? Goddammit~ it´s" John angrily grabbed the alarm clock and nearly knocked it off the nightstand in the process "6 o´clock, Sherlock! And I´ve had the evening shift!"

Sherlocks´ grin spread even wider.

He held out his device.

"Guess who´s that."

Sherlock pressed his lips together, trying to make a serious face. But failing.

John shot Sherlock an irritated look, then decided to follow the orders.

"I don´t know who´s that."

"Oh, come on, John. Try at least."

"It´s someones´ baby."

Sherlock sighed. "Right. Can´t you deduce it?"

John glanced at him angrily with an expression that said: ´After an evening shift?´

"It´s a baby, Sherlock."

Trying to put this argument to an end.

The grin reappeared.

"It´s our baby!"

"…"

"Oh don´t stare at me with this dumb expression!" Sherlock huffed.

"What do you mean ´our baby´?"

"The agency called. We´re off to Edinburgh at 2. They also sent the photo."

John grabbed the phone, gaping. Staring at the picture.

"This is…"

"Yes. He´s three weeks old."

"It´s our boy."

"Yes."

"Brilliant."

And they were smiling.
