WARNING: If you don't want to know what happens in this episode, don't read this photo recap!
We open with a flashback of Holden and Ade's meet-cute, where she repeats her mysterious final line in the previous episode, "There's something you should know ..." Before Holden can reflect on this, he snaps out of his dreamscape and is plunged back into harsh reality ...
... namely, the debris from the destroyed Canterbury pummeling the Knight. Alex's expert piloting keeps the crew from being obliterated, but the shuttle takes a beating nonetheless.
The crew's situation is pretty grim, as they have a dead radio, only about four hours of oxygen and not nearly enough fuel to get to the nearest space station. And with the airlock breached, they'll have to vent the ship to repair the outer antenna.
Holden and Amos do a 'spacewalk' in an attempt to fix the antenna as everyone dons spacesuits to be able to breathe on board the shuttle.
Soon, Alex starts going hypoxic. Shed quickly hooks up breathers to share his oxygen with Alex even though there's not nearly enough for both of them.
Shed ends up passing out as Holden fixes the antenna the old fashioned way: by kicking it. As the cabin is re-pressurized, Holden revives the heroic medic.
During the salvaging to conjure a makeshift amplifier with which to send a distress signal, Naomi notices the beacon they found aboard the Scopuli is actually top-grade military tech courtesy of the Martian Congressional Navy, which leads almost everyone to suspect that Mars nuked the Canterbury.
The crew's suspicions become stronger when they receive a response to the Knight's distress signal … from a colossal Martian warship known as the Donnager. As the Donnager prepares to jam the Knight's communications, Holden sends a message proclaiming that the Canterbury was destroyed after answering a bogus SOS from the Scopuli, from which they recovered Martian Naval technology. He hopes this information being broadcast will serve as "insurance" and keep them from being killed by their captors.
It's unknown whether the message got out as the Knight is pulled into the Donnager and the crew is taken at gunpoint by Martian soldiers.
Meanwhile, on Ceres Station, Detective Miller infiltrates Julie Mao's apartment, finding a message from her father in which he threatens to sell her racing ship, the Razorback. "It's time to come home," he says. "I'll make everything right again."
Miller and Havelock then visit the Administrative Plaza of Ceres, where a representative named Joon shows them an area of the gardens where the grass has turned brown. Joon assumes a group of local Belter gangsters known as the Greigas are once again redirecting and stealing the water for themselves ... and sarcastically presents Havelock with a gift of a small cactus.
Miller and Havelock descend into the depths of Ceres on board a conduit elevator, surrounded by pipes that feed the lifeblood of water to the station. They find the pipe to the Southeast corner of the gardens has indeed been sabotaged with the water being diverted to a warehouse.
At the warehouse, Miller and Havelock confront young Diogo and his fellow teenage "gutter punks," who have stolen the water … and claim the Greigas have left their turf to them. Respecting their survivalist defiance (but wondering what happened to the Greigas), Miller lets them go with a warning: Stay away from the awkwa.
Later, Miller visits the Docks in the hopes to find a lead on the Razorback. The Dock Master remembers Julie Mao from her teaching a rude dock-jock some manners and reveals that she was a passenger on a dumpy old transport called the Scopuli. If you've been watching, you'll remember that The Scopuli was the abandoned ship whose distress call Holden and The Canterbury replied to (only to have a hidden stealth ship blow The Canterbury up).
After going through Julie's profile on a dating site, Miller finds that she went out with a guy called 'Nightbandit31.' Is he somehow connected to her disappearance … and that of the Scopuli?
Speaking of dating, Havelock's been holding on to a little cactus given to him by Joon … and gives it to Gia, the prostitute Miller questioned in Episode 1. She accepts the gift with a smile and they disappear into Gia's quarters.
Meanwhile, at the United Nations Building in New York City on Earth, Chrisjen Avasarala has her prisoner, Heikki Sobong, put into 'the Tank,' a small saline-filled Plexiglass cell that alleviates the crush of Earth's gravity on Belter bodies. Speaking through a full-face breather mask, Heikki insists he's not OPA (the Outer Planets Alliance, an unsanctioned group fighting for Belter independence) but simply a "meaningless courier." But how — and why — was he in possession of restricted stealth technology?
Chrisjen has Heikki Sobong sent to Luna (the station on Earth's moon) for further interrogation, believing the OPA is trying to obtain stealth weapons to form an alliance with Mars. "The Cold War is over," she tells U.N. Undersecretary-General Sadavir Errinwright. "This is something new."
Later that night at her Westchester home, Chrisjen is told that Heikki Sobong killed himself en route to Luna by rejecting the high-gravity injections from his crash couch. "Earth's gravity - we used it to hurt him," says the U.N. executive assistant on the phone. "He threw it back in our face."
