The Expanse

Returning to Tycho Station, Holden and Miller butt heads about how the raid was handled. Meanwhile, Naomi and Alex deal in different ways with the post-traumatic stress of the incident. Holden and Amos interrogate an affectless scientist. Avasarala reaches out to an enemy to forge an unlikely alliance.

It's a race against time as the Rocinante chases an asteroid, now hurtling toward Earth. As Earth prepares for the worst, Avasarala is surprised to learn Holden is still alive and that the Rocinante may be Earth's only hope of averting a cataclysmic disaster.

Holden crosses his own ethical boundaries in order to sneak into the war zone on his hunt for the Protomolecule and the people behind it. Bobbie becomes a pawn in the political struggle between Earth and Mars, but Avasarala recognizes her chance to expose the enemies of humanity on both sides of the negotiation.
