In " Safe", in the aftermath of the Eros station disaster, Naomi and the crew of the Rocinante are once again on the run, this time with a sample of the protomolecule, the extrasolar lifeform responsible for all of the havoc on Eros station. Alex and the others vow to find Dresden, the lead scientist who is responsible for locking down Eros to use its population as an experiment for the bioweapon. Moments before Dresden, the principal culprit for the genocide on Eros, escapes, Alex manages to record an encoded transmission being broadcast from his stealth ship. Alex and the crew escape via the Rocinante. Eros goes on lockdown, and Miller deduces it is the work of the same people responsible for the bioweapon. Both parties realize that the trails they’re following point to the bioweapon that made its way from Phoebe. In " Critical Mass" and " Leviathan Wakes", Alex and his crew compare notes with Miller. The crew traces the Anubis’ shuttle to Eros, where they meet Miller and escape UN Undersecretary Errinwright’s team of assassins, only to discover the agent they’re looking for – Julie Mao - is dead and infected with the same strange substance. They realize the Anubis was the stealth ship that blew up the Canterbury, and is filled with a dangerous substance that must have killed the crew. In " Salvage", Alex and the crew find the Anubis at the coordinates provided by Lionel Polanski. They discover Avasarala’s spy, Kenzo stowed away aboard the Rocinante. elude detection by a Martian warship thanks to Alex’s experience in the Martian Navy. In " Windmills", on the way to retrieve Lionel Polanski, the person that can reveal who destroyed their ship, Alex and co. Fred reluctantly agrees, and Holden, Naomi, Alex, and Amos decide to stick together until they get answers. Holden agrees to lend the ship if he is part of the crew, as Lionel might be able to reveal who really destroyed the Canterbury.
DOES ALEX DIE IN THE EXPANSE BOOKS CODE
He tells Holden he needs their ship, the Rocinante, to go find the Scopuli’s sole survivor – code name Lionel Polanski. In " Rock Bottom", Alex and his crewmates arrive on Tycho, where Fred Johnson reveals that he was the one that chartered the Scopuli, the ship whose distress call starts the chain of events that destroyed Alex's ship, the Canterbury. After much debate, given Fred’s reputation, they decide to take him up on his offer, shortly before disguising the ship with the new name of the Rocinante. They receive an offer of help and refuge from Fred Johnson. In " Back to the Butcher", Alex and his crewmates escape the Donnager’s destruction through the fighter ship, the Tachi.
Though Shed is killed, Alex pilots a Martian attack ship, the Tachi, to safety away from the exploding Donnager, saving Holden, Naomi and Amos and regaining his crew's trust. The crew realizes this indicates Mars’ innocence.
In " CQB", the Donnager comes under attack by a fleet of stealth ships just like the one that destroyed the Canterbury. In his defense, he focuses on the suggestion that Naomi is OPA. Given that Alex was part of the MCRN for twenty years, he is treated better than the rest, creating distrust among his crewmates regarding his motives. In " Remember the Cant", the Martian navy detains and interrogates Alex and his crewmates over Holden’s public accusation that the MCRN destroyed the Canterbury. The message goes out just as a Martian warship, the Donnager, approaches the shuttle. Jim Holden broadcasts a public message that implicates Mars in the attack, thus ensuring he and his crew won’t be killed by Mars, for fear they’ll look more guilty. They theorize the Canterbury’s destroyers were Martian, since the distress call transponder was of Martian Naval origins and since it used stealth technology. In " The Big Empty", with oxygen dwindling, Alex and the surviving crew of the Canterbury struggle to stay alive in their shuttle. Shortly thereafter, the small crew watches as a ship with advanced stealth technology blows up the Canterbury, killing the rest of the crew that wasn't on the smaller Knight. Once aboard, they discover the distress call was planted.
In " Dulcinea", a small crew from the ice hauler Canterbury – Alex, Amos Burton, Naomi Nagata, Shed Garvey and Jim Holden – respond to a distress call from a seemingly abandoned ship, the Scopuli.
