Watson Season 2 Story Overview
In Season 1 of Watson, Sherlock Holmes is said to be dead. In Season 2, Holmes appears again. He is played by Robert Carlyle. At first, it looks like he is really back. But later, we learn the truth. This Holmes is not real. He is only in Watson’s mind. Watson has a brain tumor, and it causes these visions.
Then comes a big twist. Near the end of Season 2, the real Holmes shows up at the clinic. This time, he is not a hallucination. He is real. But there is a problem—he seems to have lost his memory. This surprise makes the story even more confusing and exciting.
The last episode of Season 2 is called “Cobalt Fissure.” This is the final episode of Watson. The show was canceled by CBS earlier this year. This episode says goodbye to Dr. Watson, played by Morris Chestnut. It wraps up his story in an emotional way.
The finale also brings in another character from the original Sherlock Holmes stories by Arthur Conan Doyle. In the end, the show tries to give a proper farewell while connecting back to the famous world of Holmes.
The episode starts with Watson in a clinic in Baltimore. He is getting ready for brain surgery. He has a serious tumor. But he suddenly runs away. He hears that Holmes is back in Pittsburgh. Watson had been seeing Holmes in his mind before, so this shocks him.
When Watson meets Holmes, he sees something is wrong. Holmes has memory loss. He is weak and sick. The doctors do not understand his illness. They keep guessing what the problem could be. Then Watson remembers an old case. He and Holmes once chased a criminal for three days. This chase took them to a dangerous place. It was a weapons site with radiation. Soldiers there wore safety suits.
Watson and Holmes were exposed to that radiation. This caused their health problems now. Watson tests a towel used by Holmes. The results confirm it. Holmes says his body has changed. He even calls himself a “mutant.” By the end, the doctors find the right treatment. Holmes starts to get better, and his memory slowly returns.
Watson saves Holmes’ life. But he puts his own life in danger. He starts having seizures. Doctors prepare him for brain surgery. There is a big risk he may not survive. Before the surgery, his team thanks him. They are very emotional and afraid for him.
His ex-wife, Morstan, talks to him. She tells him her life changed when she met him. She says she will always be with him. Morstan tells him he will be okay. She says she cannot imagine life without him. Then the surgery begins. The show does not clearly tell us what happens next.
In the final scene, we see 221B Baker Street in London, the famous home from Arthur Conan Doyle’s stories. Watson arrives there. Morstan opens the door and smiles. It feels like his dream has come true.
