Hello. I glad to share with you, my story about "Betrayal ".
Well the character, obviously must be Mycroft Holmes.
Why?
It's elementary my friends..
Mycroft knowing to much and hide so much behind his brother's eyes.
I believe he is hiding something grand and important that should be kept secret from Sherlock. I believe he's harboring James Moriarty ... alive. or in base of mi6 or in another country as prisoner or free man.
but he will not tell the truth to Brother until he himself finds out. this is called "betrayal."
