Ashford knows and has history with Camina Drummer, with both of them having worked on the docks on Ceres in the past. It is suggested multiple times by Drummer that Ashford spent a large majority of his life as a pirate.
Closely aligned with Anderson Dawes faction of the OPA, he is given the rank of Commander in an attempt to formalize the OPA Navy to appear legitimate, and is also said to be responsible for designing the "work in progress" navy uniforms. In his new position as a commander, he is shown to have become acquainted with Diogo Harari.
Throughout the series Edit
In "Delta-V", Ashford boards the newly christened OPAS Behemoth, alongside several other Belters (including Diogo Harari) sent by Anderson Dawes. Meeting with Captain Drummer, he announces that he has been sent to act as her first officer and second in command, with intent that his allegiance to Dawes faction of the OPA will help balance out Drummer and the majority of the Behemoth crew's allegiance to Fred Johnson's faction.
At the command deck, he briefly clashes with a member of Drummer's crew, based on old grievances. He admits to Drummer he believes he should be the one in command, but concedes that it is now a matter of "politics and perception", and is happy to serve under her. When Drummer decides to discourage the crew of the Behemoth from taking narcotics (after one skiff pilot dies) by spacing a main supplier of Pixie dust, Ashford discourages her. He tells her that if they and the newly established "Belter state" want to be treated as equals by the United Nations and Martian Congressional Republic they must treat people with and abide by the rule of law. Drummer reluctantly relents, and instead forces the workers to place any narcotic material they have in the airlock, for it to be spaced at a later time. After Clarissa Mao frames James Holden as a terrorist acting in the name of the OPA, Drummer fires the Behemoth's torpedo at the Rocinante, leading to the retreat of the Roci into the Ring.
When fighting aboard the Ring Station causes the speed limit in the Slow Zone to change, he and Drummer are pinned by a shifting excavator. After nearly crushes herself with the excavator in order to free at least one of the command staff, he takes command of the Behemoth. Knowing that the only way for the flotilla's many injured to survive is the Behemoth's ability to create spin gravity, he orders the ship's enormous colony drum spun up.
Ashford believes the best action during the slow zone incident is to destroy the Ring from within, which would strand everyone still in the slow zone. Not factored into his decision is this very attempt would also trigger a supernova of Sol. In turn, this action would end up killing all humans within the solar system, the very thing his plan is meant to prevent. Amos, Alex, Monica and Anna manage to convince the rest of the flotilla to follow Holden's advice to shut down all of the ships' fusion reactors. When Holden and Naomi surrender and plead to him, Ashford orders their execution and attempts to fire the tight beam communications array turned laser cannon. At that moment, having a change of heart, Clarissa Mao unleashes on Ashford and manages to force a reactor shutdown.
- The adaptation of the third novel in the series, Abaddon's Gate, was greatly abbreviated to fit within 7 episodes. It was anticipated that Syfy would not be renewing the show and the creators wanted to ensure that the story closed with a reasonable conclusion as opposed to a cliffhanger.
- Many of the character traits and plot points were redistributed among the characters.
- Sam has in general been replaced by Camina Drummer in the TV series overall. Naomi Nagata took on many of Sam's engineering responsibilities and served as chief engineer.
- Parts of the the Slow Zone Incident with Ashford were de-emphasized and many of the events in the book will be condensed. The recommendation that the Behemoth fire on the Rocinante was given by Ashford to Drummer as opposed to Bull and Michio Pa to Ashford.
