Season 2, Episode 9
A slow episode again. They haven't started exploring the secrets of Ganymede yet, it took them the whole episode just to get there.
Some new developments regarding Venus. We found out that both Earth and Mars sent a ship there, and that "there is life present in the air around the crater, despite the fact that temperature is high enough to melt led".
Biggest news was Draper admitting to Avasarala that she saw an unknown entity on Ganymede (before correcting herself). So, now the Earth also knows what was going on there during the battle. As Avasarala later said, "Eros changes everything. Just like a soldier on Ganymede without a suit."
