Appearances

Season Two

Mycroft surprises Sherlock and Watson with a visit to NYC in which he indicates he's opening a restaurant, Diogenes, and that an old acquaintance of Sherlock's needs his help. Sherlock and Watson discover the acquaintance is Nigella Mason, Mycroft's former fiancé who Sherlock slept with in order to prove Nigella's intentions towards Mycroft were monetary. ("The Marchioness")

Nigella Mason appeals to the Holmes brothers.

Having been stood up for dinner for several nights by Sherlock, he has dinner with Mycroft at Diogenes who gives him the keys to 221B Baker St. but Sherlock refuses them. Mycroft lies that their father is unhappy that Sherlock has remained in NYC and that he may withhold Sherlock's trust money (which he uses to pay Watson) and evict them from the Brownstone. He reminds Sherlock that he's making decisions for two now and to consider returning to London. Mycroft visits the Brownstone before he returns to London. Sherlock gives him a letter to deliver to their father with his decision to stay in NYC and, his thanks. At Diogenes, Mycroft rips Sherlock's letter up and calls an unknown person. He says his gambit to have Sherlock move back to London has failed ans since there's little chance Sherlock will talk to Morland, his lie won't be discovered. He indicates they'll have to come at "the problem" in a different way. ("Blood Is Thicker")

He's decided to stay.
