Throughout the seriesEdit
Diogo and several other youths tapped into Ceres' water supply stealing the liquid in order to sell in the black market. However, since they were stealing so much water, it quickly became noticeable to authorities. During a police raid, Diogo was captured by Miller who stated that Diogo should be imprisoned for 2 years before releasing him.
Diogo is on his uncle's ship, Xinglong, prospecting Ice when they're boarded and inspected by Martian Navy soldiers. The inspection reveals the ship's licence to be out of date and the Martian's proceed to shut them down. As Diogo was sleeping, his drunken uncle woke him, threw him in a airlock with his suit then, into the vacuum of space and, finally, proceeded to fling his haul directly at the Martian vessel that had previously boarded them. In response to the violent act of civil protest, his uncle Mateo's ship was targeted by a torpedo then destroyed while Diogo watches helplessly.
When Fred Johnson rallies the OPA factions into attacking a space station, Diogo joins the assault team. En route, Diogo mocks Miller for his lack of EVA experience. Upon boarding, he is hit by an enemy gel round, but is unhurt. Diogo is commanded by Miller to protect and extract the last remaining scientist in the Thoth Station terminal room, Cortázar.
Upon their return to Tycho, Fred Johnson commands Diogo to escort Cortázar and other Protogen prisoners to their holding cells. Diogo knowing that Miller killed the leader of the station, Dresden, gains a newfound respect for the former Ceres police detective and not only promises to throw him a party but also offers him a place to stay in Diogo's own quarters on Tycho Station.
Diogo is with Miller as they plant the explosives on Eros. Miller warns him to keep his mind open, realize the OPA is still a big band of gangsters, and that Belters will never be free from oppression. Ulimately, Miller takes the bomb with a defective detonator from Diogo after they survive a passing debris cloud from the destruction of Marasmus
Diogo stands guard outside Cortázar's cell when Fred asks the former Protogen scientist how to stop Eros which at that time has taken a high speed trajectory toward Earth.
Diogo rallies the crowd around a mural painted of Miller next to an OPA insignia. Diogo later proclaims "Miller, I do this for you!" as he leaves the Blauwe Blome bar with the same belter waitress, Tina, who had turned him down earlier.
The teenage Diogo enters his own home quarters to find Anderson Dawes there. Dawes uses charm to stroke Diogo's vanity in a ploy where he extracts information from Diogo about what was at Protogen Station. Dawes is attempting to learn about Fred Johnson's secret weapon. Dawes seduces Diogo with Belter pride so the boy turns against Johnson and enlists in a plot to take Paolo Cortázar from Tycho Station. Diogo serves as a decoy that Alex along with Naomi desperately and unfortunately chase down. Meanwhile, the actual getaway skiff boat that transports Dawes' prize escapes from another Tycho dock amidst the commotion despite an ordered lockdown.
Fred Johnson confronts Diogo over his part in the re-capture of Cortázar is defiant and unfazed.
