We finally get to the truth of what happend to Julie Mao. The episode gives us the events of from prior to the beginning of the series, as Julie is flying the crew of the Scopuli as part of the OPA, trying to intersect the Anubis, knowing is has come from Sophie Station, carrying a "weapon". Julie knew about what was going on on Sophie because the Anubis belongs to her father, the Mao Corporation.
The Anubis crew takes the Scopuli, using it as bait for the Cantebury in an effort to start a war between Earth and Mars, in order to divert attention from their plans for Eros Station. Shortly after, the crew of Anubis is killed by the samples they picked up from Phoebe. We lope back to the opening sequence of the series as Julie finds the crew dead and the blue stuff devoruing the corpses. Knowing that this may be a bioweapon, she hides the stealth ship and heads out to Eros, looking for safety (and an OPA rescue).
Once on Eros, Julie hides away in the rundown hotel, waiting for salvation, but her fate had been sealed when she had touched the blue stuff. It was only a matter of time before it ate her up.
Love how the show bookends with Julie, first planting the questions in the pilot and with the 2part finale, giving us answers to the fate of the infamous Ms. Mao.
Poor Miller, trying to save Julie, only to discover her body. She died alone for a cause that pretended to love and cherish her. In reality, it used her, like it uses anyone it can. For Dawes, and the OPA, she was only a pawn to a larger game.
With the samples of the blue goo, or protomolicule, the Mao Corporation moves forward their plan for Eros: inject the population with the protomolecule and see what happens when it grows.... they are using the station as a giant lab experiements and the belters as their lab rats, infecting them via fake vaccines.
Meanwhile, Christen is trying to figure out who has stole stealth tech from Mars and what are they using it for. She doesn't know it will lead her to the Mao Corporation, the pinacle of money and power in the system. At the same time Johnson releases the information from Donager ship, its info on the stealth ship that attacked them, the Anubis was built on earth. This is the breadcrumb that will lead Chrisjen to the Mao and Phoebe station.
Finally all the pieces of the puzzle are being pulled together: Mao Corporation, Julie/Miller, Phoebe station, The Cantebury, and Chrisjen. We finally we the big picture and it's incredible.
