Complete story — includes the ending
A team of Belters, sent by Marco Inaros and led by his and Naomi's son Filip, attacks a science vessel near Venus, killing all aboard. Holden and Naomi are stationed at Tycho while Rocinante is undergoing long-overdue repairs. Holden is contacted by Monica Stuart about protomolecule research she has heard about and confronts Fred Johnson about that. Naomi gets word that Filip is on the asteroid Pallas and makes plans to go there alone. Amos is going to Baltimore, Earth, to settle affairs of an old friend and is met by Avasarala during his stop at Luna. On Mars, Bobbie is working for Avasarala to investigate the ongoing Martian weapons trafficking but feels that she is running out of time. Alex arrives to Mars to try and make amends with his family but gets a cold welcome; Bobbie meets him at the bar afterwards but their conversation does not go well. On Luna, Avasarala starts investigating the possible involvement of Inaros in the science vessel attack.
