When there was a knock on the door in 221B Baker Street, the detective was surprised. John had a key, and Mrs. Hudson had no reason to come.
When he opened the door, he was even more surprised. Seeing his brother was not the thing that surprised him, it was the look on his face. He seemed genuinely confused.
He cleared the path to let his brother enter the flat.
"What happened?"
"She… Before she came here, she… She was dating Moriarty." he spit the last words with complete disgust.
"Clearly. And?"
Mycroft turned sharply to face his brother.
"And?! She kissed him, Sherlock. Emma, my Emma, kissed him!"
"Of course she did. Didn't you realize that when she said that she did it because he asked her to?"
Mycroft's hands clenched into fists. He felt a sudden urge to hit his brother.
"What if you found out that John dated Moriarty?"
"John has nothing to do with this." Sherlock said with a dark expression.
"Oh, he has everything to do with this. In fact, why shouldn't I call him right now, and tell him you secretly dated Moriarty before you faked you own death?"
"He won't believe you." the younger brother chuckled in contempt, but his worry was clear in his voice.
"I'd bet my life that he will."
The two brothers looked at each other, as if they're in the middle of a staring contest.
Sherlock's expression suddenly changed.
"You didn't leave her alone, didn't you?"
Mycroft's expression changed as well.
He opened his mouth to say something, but then Sherlock's phone rang. As he saw his boyfriend's name on the screen, he answered the call quickly.
Mycroft could hear John's voice, as he was speaking loudly.
And his words were: "Sherlock, it's Emma. She was attacked."
Mycroft ran out of the flat before his brother even managed to hang up.
