The Habits of a Lifetime
Summary:
The idea of Sherlock and Eurus connecting over music, over anything, is terrifying. Mycroft has spent decades watching over Sherlock, talking about their fictional family dog and the myth of the east wind, trying to protect Sherlock from the things he doesn’t remember. He’s worried about Sherlock and stood guard over Eurus, and been worse than useless in the end. He was complicit. While he thought he was juggling both threats, maintaining enough control over the situation to keep everyone safe (mostly Sherlock, but the rest of the world as well), he had allowed the threat to escalate.
In which Mycroft is not an easy man to know and an even harder one to look after. Fortunately, Lestrade is diligent and determined, and knows how to pay attention to people. Where family comes with obligations, but it also cares, even when you don't want them around. Where life mostly goes as expected, but sometimes has unanticipated joys.
