How Will ‘Watson’ End? Series Finale Details Revealed

Morris Chestnut as Dr. John Watson — 'Watson' Season 2 Episode 15 'A Third Act Surprise'

What To Know

  • Watson will end after two seasons, with its series finale airing on Sunday, May 3 on CBS.
  • The network has revealed details about the last episode.

Sadly, Watson will be ending after two seasons this May. And what makes that even more unfortunate is the new information that has been released about the series finale — it sounds like this could be setting up what would have been a great Season 3!

On Thursday, April 9, CBS released the official descriptions for its finales, and Watson‘s was one of them. In the Sunday, May 3, episode, titled “The Cobalt Fissure,” the network teases, “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.”

If the words “cobalt fissure” are familiar to you, they should be: They came up in relation to Watson and Sherlock’s past adventures. However, as recent episodes have revealed, Sherlock isn’t really alive — or, well, the Sherlock that Watson has been seeing isn’t, since, after all, who knows what could be revealed still. But for now at least, the doctor has been hallucinating the sleuth, and he attributes it to the traumatic brain injury he sustained following Sherlock over the waterfall and cutting back on his meds.

But who could this person from their shared past be who pops up in the finale? Will it be a name familiar to fans of Sir Arthur Conan Doyle’s work? When it comes to seeing Sherlock Holmes characters from that this season, executive producer Craig Sweeny seemed to rule that out when speaking with TV Insider.

“I think we’re pretty full. We have this gallery where we’re trying to fight to get everybody in. I wouldn’t say we’re going to drop an arc with Henry Baskerville,” he said. “It’s nice to have those characters out there and to be able to think about them, but we’re sort of playing in the sandboxing with the characters that we have.”

But that was also in December 2025, so we’ll have to wait and see just what the finale holds. Share your predictions in the comments section below.

    Watson is not the typical medical show and does not deserve to be canceled. I look forward to watching every week

    I hate when they finally get a show with a new premise and then cancel it after only one or two seasons. Then they bring another cop show, fire station show or same old medical drama when we already have so many. I’m sad to see Watson go.

    They keep Survivor and cancel Watson? The dumbing down of television watchers is on

    This has been an excellent drama and the people playing these characters have been very good....hopefully the show will be picked up by another network and go on.

    Watson is one of the most unique shows on broadcast tv. The ensemble all work well together. Each case is better than the last.

    CBS - you have been cancelling good shows for years. Little by little, broadcast shows will all be gone- and the truly good shows will be found on streaming channels. But isn’t that what is happening now anyway?

    Like a previous poster said, I really hope another network (or streaming service) picks this up …..

    Watson was a great series , I am so disappointed it was canceled . I do wonder if the time it was on was too late at night and didn’t get enough people watching it. I wish Watson would get picked up by another network. It’s been my favorite show to watch.

      I agree that perhaps it was shown too late and would have done better at an 8 o'clock or 9 PM time. I always looked forward to Sunday night so that I could watch Watson. It was indeed one of my favorite, must – see shows. I really hope that the show returns.

    I am so sad!! Every single actor was perfect!! Maybe another station will pick it up?!? Ingrid is the best!!

    I just hope Ingrid calls out the hateful jerk who's messing with the other doctor (he's trolling her pretending to be her birth other in China). it will be extremely hurtful to the young woman, but she needs to know what happened.

      She not only calls him out, she kills him.

    I always hate when they cancel a TV series after one season or end it with an open ending/ cliffhanger. That’s why I only watch TV series either when it is completely finished or if the season does not end with an unresolved ending. Otherwise, too frustrating and I felt like a loved one died suddenly without any last words especially if I enjoyed the series. Though I cannot prevent someone from dying, I can control my frustration from the cancellation of a TV series, especially when it is an undeserved cancellation.

    I truly hope this drama gets picked up by another Network. I have enjoyed watching it weekly and have been excited the new introductions to real life illnesses.

    This has been one of my must see shows. Can't believe CBS canceled it. It is so different than most of the medical dramas. I for one will really miss it. CBS, you made a great big mistake.

    So upset the show is getting cancelled. I also wish that another network would pick it up, Like Netflix.

    Please don’t cancel Watson! It is one of the best shows on TV! It is well written with a great ensemble of actors. What a shame to cancel such a truly wonderful show. The Sunday night 10:00 time slot is terrible for any show. Sport programs run late from the afternoon, therefore the prime time shows start late. Watson use to be on another night making it a more desirable time. This cancellation is truly a mistake!

      Watson aired on Monday night opposite Monday Night Football, then went back to Sunday.

    This show is so interesting it NEEDS at least one more year. The characters have become SO interesting....

    This has been an excellent series. The actors and the stories have all been great. Loved it so much I purchased the first season. Disgusted and disappointed in the network for cancelling it, but not surprised. CBS as a network, in my opinion, is horrible. They seem to prefer big box series like _____country, etc. instead of ones that are thoughtful.

    Sad to see this show cancelled. I’ve watched every episode and looked forward to it each week. Great actors and actresses. I’ll be watching less and less tv as the few shows I enjoy go by the wayside. I’m sure there are plenty of us who watched that weren’t accounted for in their “low ratings!”

    They're always canceling my favorite shows😖

    I'm sad to see the series ending. it was one of my favorites, the cast worked well together to make the show very entertaining.

  22. S

    Shaun

    Well if the show would had more if Watson and Sherlock together. In the storyline. Not just drop Sherlock in and one episode. Then fews episode later come up. Even if Sherlock there or not. Was worth seeing Robert Carlyle herr as Sherlock

  23. J

    The real Sherlock is going to show up

    CBS stinks for cancelling Watson. You put on Marshall's to succeed and cancel a good Medical show. I'll find me another network to watch.

    They cancel Watson, but keep the series Marshalls, to go along with FBI, CIA, NCIS and that every disgusting show SURIVIOR and what other letters they can come up with. CBS SUCKS!!!! Here is your shocker, CBS is letting go of just about all of the journalists on 60 Minutes.
