7. Janine Returns! - Another love interest of Sherlock's and Mary's close friend, Janine will return for the upcoming season. According to Moffat she will definitely be back and her and Sherlock will be friends. The writer told IGN:
"He likes her, though. He'll see her again. They'll be pals. I loved Yasmine's performance as Janine -- she still likes him in the end. At some point, you know, if Sherlock Holmes has to go to a function and he needs a date, he'll phone her up. Now, he'll not expect her to say no. She'll be very cross with him, but she'll show up, and they'll have a good time. They will, because he likes her."
