Sherlock: After Mycroft's Death

"As far as he's concerned, I'm his arch-enemy. Heaven knows that's all in his head."

"Sherlock! Can't you stop making Mum and me worry about you?"

"Sherlock Holmes! If you don't stay away from drugs, I may have to consider using the coercive measures available to a minor government official!!"

"SHERLOCK HOLMES! I've spent my entire life cleaning up your messes!!!!"

Sherlock looked at the gravestone before him and lowered his eyes.

He thought their relationship was one of mutual destruction, but only now did he realize that all along, it had been nothing more than his own childish antics.

This man had died because of Sherlock's childishness. And Sherlock hadn't even seen him one last time.

After Mycroft died, even breathing became difficult.
