As we’ve seen in the season 2 premiere promo, Sherlock finally meets his brother, Mycroft in London. However, if you think that it’s going to be a happy family reunion, think again!
Read on for the spoilers:
It won’t be pleasant, especially when Joan and Mycroft (Rhys Ifans) decide to exchange notes on Sherlock. “Sherlock is expecting to go to London and never even mention to his brother that he’s there,” executive producer Rob Doherty says. “Sherlock has to confess to Joan that he has a brother. It’s news to her. We find out there’s some bad blood between the Holmes boys and they have not spoken in several years.”
