Brothers
"John."
"Piss off, My-...?"
"Mm?"
"...Usually you address me by my title."
"Indeed."
"...What do you want? If Sherlock's been refusing a case from you again he'll not listen to me about it."
"Certainly not."
"So what is it, then? You don't need me to spy on him."
"Again, certainly not."
"So?"
"Must our visits always center on my baby brother?"
"...Well. They always have before."
"Hm."
"...So then...Wh- Sorry, I'm just not understanding what you're here for."
"You have been my brother's friend for several years."
"Uh, yup."
"He cares deeply about you."
"Does he?"
"As deeply as Sherlock may."
"Mh."
"I care about the things about which Sherlock cares."
"Disgusting."
"Do grow up, John."
"So you care about me."
"You have been good for him. In whatever capacity."
"That doesn't answer the question."
"Mm, clever one, aren't you."
"Piss off, Mycroft."
"I find myself appreciating you as my brother's friend, John. You are...a good man, from what I understand. I think that perhaps his insistence on including you in family matters was not misplaced."
"...Uh?"
"I suppose what I mean to convey is that, should you require assistance with anything at all, consider my resources at your disposal just as they are at Sherlock's."
"...Have you just adopted me as your second brother?"
"Good day, John."
"...Piss off, Mycroft."
"Mm."
