Watson Season 1 Ends With A Crucial Fatality — Read Finale Recap

Watson's Season 1 finale starts with two key players on the edge of death and ends with someone dying in dramatic fashion. But is the fatality the character you're thinking it is? Read on for the highlights of Episode 13, "Your Life's Work Part 2."

WHICH BROTHER GETS THE VECTOR? | The situation has only gotten worse since we last checked in with Watson & Co.: The Crofts are still comatose, they're now intubated (aka not breathing on their own), and there's still only enough of Watson's treatment to save one of the brothers. It's an impossible choice, and the team struggles with what to do. "Fate has to decide here," Watson says, pulling out a coin and noting that it's something Sherlock would do. "Hopefully, Sherlock's wisdom guides it." He tosses it in the air, but we don't know who it favored until after the vector is administered (via shooting it directly into his brain) and the patient wakes up.

"Where's Stephens? Is he OK?" Adams asks, revealing himself as the twin that fate saved. Stephens isn't dead, but he's still in a coma and it's not looking good. Adams argues that they should have revived his twin; Watson says they still have a few days before the virus kills Stephens. But given the lesions growing in his brain, even if things go well, "what's going to be left of him when he wakes up?"

SHINWELL IS BACK! | Watson calls Shinwell and tells him that he doesn't care if he feels guilty: "If you think that you can help, we need you. Stephens needs you." So the Brit returns to the hospital, where Watson observes that he seems unwell. Shinwell brushes that off and say there may be a play they can use. So he reaches out to Moriarty's lady agent/fake pharmaceutical rep, offering her sick daughter treatment at Watson's clinic if she cooperates.

The rep's daughter, Ashleigh, is 9 and very ill with a brain tumor. Shinwell takes the rep aside and asks her to grab some of the antidote to the sickness that pushed Stephens into a coma, because the mad scientist must have some lying around. "It's suicide to cross Moriarty," she points out.

The good news: There's a chemo-based treatment for Ashleigh, and it has a 90% survival rate. The bad news: Her weight is too low to be able to tolerate the strong chemicals. "If we can put 15 lbs. on Ashleigh Burke, we can save her life," Watson explains to Ingrid and Sasha. Just then, Ashleigh's oncologist, whose name is Laila (played by The Haves and the Have Nots' Tika Sumpter), shows up. She's skeptical of Watson and his clinic, given how often charlatans give false hope to families of terminally ill children and squander the kids' final days by chasing treatments that will never work.

INGRID FULLY GOES TO THE DARK SIDE? | Moriarty intercepts Ingrid while she's hanging out at her sister's physical therapy session. He gives her his card and contact information: "This isn't about orders anymore," he says. "It's a collaboration now."

Sasha slips into Stephens' room to tell him how much she cares about him. "I hope that you can hear me now, and I hope that you remember this," she says, bending down to kiss him on the forehead — which is when he starts to have a seizure. Ashleigh has one at the same time.

Ashleigh's seizure, at least, gives the docs some important intel: Something other than the tumor is causing her weight loss. After some tough words from Sasha, the rep starts to talk. "Moriarty won't kill many people," she says. 'He'll kill the right people." OK then! Using what she tells them, they start to zero in on where Moriarty's lab is. And when Watson finally gets Shinwell to let him examine him, he sees that the older man's back is torn up with rash, but Shinwell won't submit himself to any medical help until Stephens is better.

Ingrid contacts Moriarty and indicates that she's done playing nice at Watson's clinic. "They know about your lab," she says, advising that he get anything important outta there quickly. He talks about extending one's will into the universe, and how only a few people can do it. "Welcome to the only club that matters," he says, and she seems pleased.

SOME GOOD NEWS | Watson figures out that Ashleigh's body can't process some ingredients in the meal-replacement shakes she's been served; using an older formula will help her gain weight.

The rep tells Shinwell that her real name is Hannah (or Anna? Damn that beautiful British accent!), and she looks very scared as she prepares to go into Moriarty's lab and steal the vector. But it doesn't matter, anyway, because the mad scientist has acted on Ingrid's warning, and his goons show up ready for a fight. Just then, Watson calls them back; they narrowly escape.

Watson tells Hannah that Ashleigh will be able to have surgery as soon as she gains weight; she gratefully leaves when he adds that he doesn't need her anymore. A stymied Shinwell wonders what's up, and that's when Ingrid starts telling all kinds of truth to her teammates. In quick succession, she admits that Moriarty came to her, too; that she killed her father after he grievously injured her sister; and that she ruined the vector. "The reason Stephens is barely alive, the reason he may have brain damage already, is me," she says, crying. Watson tells them all that Ingrid told him everything the night before, and they laid a trap for Moriarty, who's on his way.

Ingrid explains that when Moriarty came by and gave her the stuff to mess up the vector, he also inadvertently gave her some cuticle skin. Watson used it to cook up a substance that would make only someone with Moriarty's DNA really sick; Ingrid arrived at the meeting hours ahead of time to coat every surface with it, practically ensuring that Moriarty would fall ill afterward.

"He knows that I'm the only person on the planet that can keep him alive," Watson says... and just then, Moriarty shows up. "What did you do to me?" he asks. "I can't see!"

WHO'S ON TOP NOW? | Moriarty tries to negotiate, but Watson isn't having it: "James Moriarty, you want to die today?" he wonders. And since Moriarty brought the vector with him, they immediately get to work.

Both Stephens and Moriarty undergo their respective procedures. Stephens wakes up, un-brain-damaged, to find his brother waiting by his bedside. Adams apologizes for dating Lauren, calling the move "selfish," but promises that they're really in love. Stephens understands and says he's happy for them both. Then Sasha stops by: "I kissed you when you were sick." Then she does it again.

Eventually, Ingrid stops by. He thanks her for helping him live, even if she was the reason he got sick, "but I can't work with you. You have to go." So she does.

'YOU ARE THE HARM' | When Moriarty's eyesight has returned, Watson comes to his room for a reckoning. Holmes. The Crofts. Drugging Watson himself. What was the point? Anyway, Watson says the cure didn't work the way he hoped and "I'm concerned you may have a stroke in the very near future." Moriarty realizes that the "cure" Watson gave him could be the reason he winds up dying, and points out that doctors take an oath to help the sick. "'First, do no harm,'" Watson says. "You are the harm, James Moriarty. I treated you, but for the good of the word, I'm glad you are not going to be walking out of here."

Oh, wait, he means Moriarty is going to kick it NOW. "So you're going to die with your secrets, eh?" Watson says as Moriarty starts to struggle. "What else do I have left?" Moriarty chokes out, then has a seizure and dies while Watson watches.

Two weeks later, Watson and Laila are on their third date; she's cooking for him at his place. He folds up Moriarty's "Always & Everywhere" polo and puts it in the box marked HOLMES that he slides under his bed.
