While everyone answers to someone, Mycroft answers for someone too. He answers for Sherlock; he always will, so long as it is in his power, and power is what he’s most fluent in.
This is a great character study of Mycroft’s devotion to Sherlock. If you’re looking for brotherly love in properly dramatic Holmes-style, this is the fic for you.
Decent – Such an interesting and revealing portrayal of Mycroft.
