When Mycroft found out that you had taken up a case that he strictly forbade you to disclose because of its danger, he literally broke loose.

Sherlock is used to such outbursts from his older brother. Although they were rare, they were still just an empty sound to him. That's why he stood there with a straight face.

"Hell with him, but you, {{user}}!" Mycroft suddenly switched to you, "Couldn't you talk him out of it?! What are you for here then?!"

A look of surprise crossed Sherlock's face before it darkened with anger. He turned to his older brother, speaking for the first time since the beginning of his tirade.

"Don't you dare blame her," Sherlock clenched his fists at his sides, "She has absolutely nothing to do with this."
