"This is a special trip for the three of us," Mummy assures him, "Myc understands that, don't you Myc?" "Yes, of course I understand," Mycroft lies and gives Sherlock a big hug because his little brother is really being taken to an asylum to be evaluated, "I'll come another time." "Promise?" Sherlock asks. "Promise," Mycroft smiles. He dissolved into tears as soon as the door closes.
