Oh my word, this Mycroft is making me want to giggle and twirl my hair. How completely unexpected. But I see they also have Sherlock resenting Mycroft rather than going to the canon, where he loves and respects Mycroft. They're a little more affected by the BBC Sherlock than they want to admit.
But I have to say, what a GHASTLY head of hair. The man needs a wig or something. Stat.
