Mycroft Holmes: Everyone Dies. All hearts are broken. Caring is not an advantage.
littleasskicker: As ever, I’m concerned about you.
I like how Sherlock can't believe Mycroft wouldn't be good with babies. Do these 2 not know each other?
Mycroft is Mary Poppins: Confirmed
Mycroft understands the struggles of introverts
Even though the pair may hate each other both know that they wouldn't last a day without either of them both
Mycroft to Sherlock. That was a well-done brother moment.
