After most of a season of suspense, CSI: Vegas revealed the Silver Ink Killer — but also proved he wasn’t acting alone. “We All Fall Down” ties together the last threads of that mystery, starting with poor Molly Tate being dumped in a shopping cart while Maxine Roby runs into her ex-husband Daniel. Silver Ink’s accord intentionally leaves his fingerprint so the team can identify him as Ronald Winter, whose plan is quickly revealed. “He’s using her body to poison all of us,” Max declares when coroner Sonya Nikolayevich collapsed shortly after finishing Molly’s autopsy.
Sonya is rushed to the hospital, and after Max calms down Sonya’s brother Jack, Folsom questions her plan to interrogate Ted Hester since she’s the person he’s always wanted an audience with. Max is undaunted, so she and the underutilized Catherine Willows visit Ted in prison. He’s as smarmy as one expects, while Jack and Allie Rajan re-examine Molly’s body using Sonya’s autopsy notes. The two are able to determine how Molly was poisoned and extract a sample. Allie has no clue how big a part she’s about to play.
At Molly’s home, Folsom and his girlfriend Serena Chavez easily deduce how she was abducted and dragged to her eventual death. Just as they find a piece of cloth on the scene, her mother arrives and Folsom is unable to console someone for once. He returns to the crime lab to find that Allie hasn’t been able to identify the poison, but as the search goes on, everyone answers an unexpected call from Winter. He says he’s not acting on Hester’s orders — he’s working on something “much, much bigger” and wants to “lighten” [their] workload.” Winter’s father appears in the crime lab shortly thereafter, and Max shows his son’s overly wordy texts. Could they be useful?
A frustrated Jack lashes out over the lack of forward progress, smashing a beaker against a wall. Allie promises him that they’ll save his sister. CSI: Vegas contrasts a quiet moment between friends with another tense one between Max and Daniel. He apologizes for changing and gives her keys to his place in Henderson as an attempt to protect her from Winter. After finding out Sonya has been put into a medically induced coma, Max and Catherine want to interview Hester again… only to find out that he, too, has been poisoned. Winter wasn’t kidding about not being Hester’s lap dog.
Jack and Allie examine Hester’s corpse and confirm he was poisoned via cupcake, while the former makes a reference to the prison break from The Shawshank Redemption. Winter offers another deadly dessert to his dry cleaner to further cover his tracks, then decides to call the crime lab again. This time, Allie answers and he seems to be particularly fond of her, telling her she’ll like what he has planned that night. Conferring with the rest of the team, she identifies the poison as thallium. Sonya gets the antidote for heavy metal poisoning, while Max logs in to Winter’s favorite online game to figure out what he was hinting at. She decodes that he’s going to aerosolize the thallium in order to poison the entire population of Mountain Vista Psychiatric Hospital: 293 people.
The whole CSI: Vegas team rolls up to the hospital, determined to find Winter’s dispersal device. They don’t know that he’s also in the hospital, literally just steps ahead of them. It’s Catherine who finally recognizes him when he walks by her, setting off a pursuit. Folsom is the one who tackles Winter — but there’s less than a minute left on the thallium device. Beau Finado thinks very quickly and contains it in a giant plastic bag. On his way into custody, Winter refuses to tell Penny Gill what his secret code meant, but does stop to talk with Allie and is upset that she doesn’t subscribe to his philosophy. The episode — and the story arc — ends with Sonya coming to in front of her brothers, Allie and Josh, though she still has a “long road” to recovery ahead of her.
CSI: Vegas airs Thursdays at 10:00 pm on CBS. New episodes return March 30.
