By the time Sherlock Holmes 3 finally hits the silver screen, it will be nearly a decade since Sherlock Holmes: A Game of Shadows came out.
A Game of Shadows explored this with Watson’s marriage to Mary Morstan, but since Holmes and Watson will have been separated for years when Sherlock Holmes 3 picks things up, who knows how that will affect their relationship.
Rather than have the threequel take place immediately after A Game of Shadows, as Jude Law told EW, the next movie will instead play off the fact that Holmes and Watson haven’t seen each other in years.
Not to mention the codependency element that Law also mentioned.
