‘Watson’ Season 2 Episode 19 raises questions as major Sherlock Holmes twist sets the stage for finale

Fans were dealt a huge blow when it was announced that CBS was cancelling ‘Watson’ due to poor ratings. Despite the news, Season 2 continues the thrilling ride that made many fall in love with the procedural drama. The penultimate episode, titled ‘The Rule of Three,’ saw the arrival of one of the biggest characters in literary history- Sherlock Holmes. Sherlock was killed off in the show after apparently falling to his death. The series kick-started around a year after the supposed death of the world’s most famous detective. Since then, Sherlock, played by Robert Carlyle, has made multiple appearances, but all of them have been speculated to be a figment of Watson’s imagination. This episode flipped the theory on its head when Sherlock arrived as a patient in ‘Holmes Clinic.’

During the show’s last few moments, Shinwell Johnson (Ritchie Coster) was called into the ER to treat a patient who had a paper with the administrative aide’s name on it. “There’s some guy down there, and he’s in bad shape. We don’t know who he is, we don’t know why he’s here, but he’s holding a piece of paper, and it’s got your name on it, and your phone number,” a staff member informed Shinwell. What awaited him in the ER was shocking. The patient in question was none other than Sherlock. “My god,” Shinwell said, walking over to the patient. “Sherlock? Guv? Are you alright?” The famous detective looked at him and asked, “Do I know you?” It seems that the detective remembers nothing about his past, so does that mean he is suffering from amnesia? Fans will have to wait till the series finale to get their answers.

The show will return for its season finale, “The Cobalt Fissure,” on Sunday, May 3, 2026, on CBS. As per TV Insider, the finale’s synopsis reads, “A seemingly random murder outside of UHOP sets the stage for the arrival of someone from Watson [Morris Chestnut] and Sherlock Holmes’ [Robert Carlyle] past.” Fans are hoping that the series finale will tie up several loose ends. Will Ingrid be apprehended? How will Watson react to Sherlock’s comeback? What happened to Sherlock? One thing is for sure: the legendary duo will grace the screens for an epic farewell.
