Instinct

Mycroft is the brain behind the masterplans, the engineer behind the elaborate schemes. In many ways, he is the polar opposite to his younger brother. Where Sherlock is chaotic, Mycroft is systematic. Where Sherlock plunges into situations headfirst and careless of the consequences, Mycroft follows at a slower pace, always judging the possible outcomes as they present themselves. If Sherlock is the storm, then Mycroft is the calm before it.
