Apple TV‘s hit sci-fi series Dark Matter ended its gripping sophomore season with an eventful finale, a devastating loss, and a heartbreaking cliffhanger that will leave viewers fearing for the fate of several fan-favorite characters.

When we last left Dark Matter, Jason 1 and Jason 2 (Joel Edgerton) met face-to-face and hashed out the past. Charlie (Oakes Fegley) hopped in the box solo and traveled to a world where he could meet his late twin brother, Max. Daniela (Jennifer Connelly) went on her own adventure, hoping to find Charlie. Agent MacNamara (Chris Diamantopoulos) took his first and final spin inside the box. The OG Jason and Ryan (Jimmi Simpson) reunited in the same world, as did Blair (Amanda Brugel) and Amanda (Alice Braga). And as Leighton (Dayo Okeniyi) started seriously second-guessing the technology after seeing the destruction it caused in alternate realities, the four friends devised a plan to shut down the OG box before Leighton got his Pyramid online.

Dark Matter Season 2, Episode 10, “No Quiet Life,” promised “a high-stakes gambit [that] leads to unintended consequences.” And boy did it deliver! Did Jason and friends shut down the OG box? Did Leighton get his pyramid online? Did Ryan and Amanda find a cure for their plagued Chicago? Did Daniela find Charlie? And will there be a Dark Matter Season 3? Decider’s Dark Matter Season 2 finale recap has answers. Just be warned, Dark Matter Season 2, Episode 10 ending spoilers lie ahead.

Dark Matter Season 2 Ending Explained: Dark Matter Season 2, Episode 10 Recap “No Quiet Life”

Dark Matter‘s Season 2 finale picked up on the heels of the penultimate episode’s shocking end. After Daniela and the Jason she was traveling with return to the box, he asked if she remembered when Max got scissors and cut Charlie’s hair. As she was fondly reminiscing, he opened a door, led her to a happy version of their world where Max was still alive and he believed Charlie went, and let her go. Daniela headed to her house, grabbed the spare key, and started looking around only to come face-to-face with the version of herself in that world.

Meanwhile, Ryan and Amanda met Oluko at Velocity Labs and recieved the cure and vaccine for the Black Iris Plague, the same disease Leighton found in his grandfather’s world. The two then headed to the box and met up with Jason and Blair, who devised a plan to shut down boxes everywhere by traveling to the OG box’s world and installing the hacking multi-tool Blair created. The technology would upload a nasty code and implement Jason’s disentanglement scenario. Then? The boxes would be dead! The group grabbed stopwatches and ampules, then split up and agreed to meet at the Village Tap in an hour. Jason and Blair gave Ryan and Amanda a head start to deliver the vaccine to the plagued Chicago, but Oluko sent his colleague Sandra to stop Jason and Blair from getting in the box. After Sandra shot at them, the trio fought inside the box and found themselves in a dangerous world full of burning buildings, explosions, and soldiers attacking them. Dark Matter went full-on action movie as Jason, Blair, and Sandra narrowly evaded death and returned to the box, only to open the door to another dangerous wold that ultimately took Sandra’s life.

In a calmer twist, after Daniela’s introspective journey these past few episodes, she finally found what she was searching for as she sat opposite herself. She explained to the other Daniela that she wanted to be in her marriage if Jason and knew they could find each other again like they always did. The other version of Daniela told her, “Jason’s the only one I’ve ever talked to about our childhood,” to which the OG Daniela admited she never talks about her traumatic past with her Jason. “You have to forgive yourself,” new Daniela told the OG. “Someone came into your home, threatened you and you family, you protected them, and you protected yourself. You fought back. And this isnt Jason saying this to you. It isn’t papa. It isn’t a therapist. This is you talking. Forgive yourself. For everything. Go live your life with your beautiful family.” When Charlie returned, content with his time spent in the world and happy to see his mom, the two headed back home. Before they left, Daniela even got to share a sweet moment with Max. But this is Dark Matter, so naturally, chaos awaits!

After Leighton’s eye-opening detours, he finally returned with the part needed to bring his Pyramid online. But along the way, he had a change of heart. In an honest chat with Jason 2, he recounted the horrors and devastation he witnessed — all negative consequences of the box — including a version of him that let millions of people die of a plague for money. “This thing has brought out the most terrifying aspects of who we are. Blair’s right. We can’t control it,” Jason 2 said. “We can’t change what’s happened, but we could stop the Pyramid from going online ever again.” Leighton agreed and revealed he’d installed an emergency kill switch in the Pyramid. The two decided to kill their big tech dreams together and embrace a different kind of life, like co-owning a bar!

Back in the box, Blair and Jason raced to recover from the time wasted fighting Sandra, while a stressed Amanda and Ryan struggled to find the plagued Chicago. Before disabling the Pyramid, Leighton went to share the new plan with Okulo, who was largely unphased by the horrors that led to Leighton’s epiphany. “Consequences of inventions are always immense and unpredictable. But they pale in comparison to going backwards,” Okulo argued. “The difference is this time around I’m the one responsible. Just because I invented this thing doesn’t mean I get to decide what’s best for other worlds,” Leighton concluded.

The two fought over their differing opinions, and when Okulo learned that Leighton already talked things through with Jason 2, he snapped, hit Leighton in the head, and tearfully strangled him to death. (NO!!!!!!!!) While it’s ironic and errily fitting that Leighton — by way of the dangerous technology he made, and a literal version of himself — was responsible for his own death, we’re still devastated to see him go, partially because we were looking forward to an iconic redemption arc, but also because Dayo Okeniyi is so incredible in the series! Agh!

As Okulo raced to get the pyramid online, Blair and Jason arrived at the OG box, input the code, and started the 10-minute countdown clock. Seconds after they smashed the “EXECUTE” button, however, armed guards rushed the lab to investigate the breached box. Though Amanda and Ryan finally made it back to the plaged Chicago to deliver the cure, guards held them at gunpoint as the clock ticked. With less than 10 minutes left in the countdown, Jason and Blair made a run for it and successfully entered the box. And after Leighton arrived on scene to review the vaccine, he let Ryan and Amanda go as well. Meanwhile, Jason 2 faced off against Okulo and managed to take the pyramid offline — but not before Okulo made his escape to another world. As Jason 2 found Leighton dead in their offices and mourned the loss of his friend, Blair and the OG Jason made it back to their world with 58 seconds to spare! Amazing, right?! Think again!

Ryan and Amanda’s fate was still unknown. But in the midst of all the chaos, Jason — and possibly even viewers! — forgot about Daniela and Charlie. In Jason’s defense, he assumed they were still safe and sound in his world and had no reason to believe otherwise. But in reality, Daniela and Charlie were just getting ready to leave the alternate Max world they visited. After they took the drug and Max went to open a door in the box, however, Jason’s alarm beeped and the boxes were successfully “dead as a doornail,” leaving Daniela and Charlie trapped lord knows where!

After Blair and Jason made it back just under the wire, she headed to the Village Tap, where (an alive!) Ryan and Amanda were waiting, while Jason stopped home. After he tore down his I’m Obsessed With The Box wall, he finally found the note Daniela left him, which read, “Jason, Not sure where you are. I think Charlie went in the box looking for Max. I’m going in after him. I love you. Daniela x” A distraught Jason, realizing he’d just trapped his wife and son in an alternate reality with potentially no way to return, headed to the bar and poured his emotions out to Amanda.

As Simpson teased in his pre-finale interview with Decider, “Just like life, you make these great, fantastic plans, and they’re all coming together. But then there’s this one unexpected reality that you couldn’t even possibly prepare for.” From the start of Dark Matter, we’ve watched people use the box to pursue ideal scenarios, only to be unhappy and unfulfilled when they arrive at their intended destination and achieve those ambitious dreams they thought would fix everything. The latest example is utterly heartbreaking.

After Jason, Amanda, Ryan, Blair, and even Jason 2 breathed huge sighs of relief ahead of disabling the OG box and Pyramid, they’re about to be filled with a familiar — albeit heightened — sense of dread and a new, overwhelmingly massive, life-altering problem to fix. The stakes feel higher than ever for Jason. So what exactly happened to Daniela and Charlie when the boxes got shut down?

Before the end credits rolled on Dark Matter Season 2, we got a glimpse of Daniela and Charlie opening the door of the box, breathing shakily, and taking in the mysterious world outside. What exactly they saw, and whether there’s any chance of them reuniting with their Jason down the line, is unknown. What we do know is we need a Season 3 renewal ASAP, Apple TV!

While we wait for more updates, here’s everything we know about Dark Matter Season 3, including hopes from star Jimmi Simpson.

Dark Matter Season 2 is now streaming on Apple TV.
