## What Happened in the Episode?

Watson visits the unrenovated section of the clinic and hears someone playing the violin. To his shock, it’s Sherlock Holmes — disguised as a hospital caretaker — who claims he traveled to Copenhagen, had brain tumor surgery, and is now ready to return to solving cases and possibly even open a London office together.

Meanwhile, the medical case involves a young woman named Hollis Pitter who urgently needs a kidney transplant. The team uncovers a disturbing fertility scandal — the fertility clinic’s own doctor secretly used his own genetic material, leaving Hollis with 42 half-siblings. The resolution comes from the doctor’s identical twin, who agrees to donate a kidney in exchange for immunity — saving Hollis’s life.

## The Shocking Ending Explained

In the final moments, Watson tries to introduce Sherlock to Detective Lestrade — but Lestrade says, *“There’s no one there,”* and the camera pans to confirm it. Sherlock simply does not exist in that room. [Cinemablend](https://www.cinemablend.com/television/after-getting-cancelled-cbs-watson-delivered-john-sherlock-twist-questioning-everything)

This twist suggests Watson himself may be suffering from a serious neurological condition — mirroring the brain tumor arc originally assigned to Holmes. The show was inspired by the legendary literary character; learn more about [Sherlock Holmes on Wikipedia](https://en.wikipedia.org/wiki/Sherlock_Holmes).

Showrunner Craig Sweeny has hinted that there are clues pointing both ways — things that indicate Sherlock is not real, and also things indicating that he is.
