The Expanse season 5 episode 5 is coming this week on Amazon Prime Video, with the title "Down and Out." Marco Inaros (Keon Alexander) remains to be the biggest adversary here. He is capable of doing whatever he wants, especially now that he's seemingly more powerful than others.

Earth and Mars are one of the major concerns in The Expanse season 5 episode 5. It can be noted that Marco and his Free Navy can control the protomolocule now. They were able to grab it as a part of their plan that resulted in Fred Johnson's (Chad L. Coleman) death.

Fans have been anticipating Marco and Fred's ultimate showdown, but many were shocked when the Tycho Station leader dies early this season. In episode 4, the traitorous Belter fatally shot him, leading to his demise. Marco has no problems in hurting those who oppose him.

He will do whatever he can -- and willing to kill -- to get what he wants. In fact, he's done something devastating to Earth and Mars to send his message to the people. He is capable of killing whoever comes his way to make his vision happen.

What makes Marco an even more dangerous villain is that he believes his ways of doing and dealing with things are right. In The Expanse season 5 episode 5, he's going to further with his goal, and he won't stop until he achieves it. The most challenging part here is finding a way to stop him.

Everyone must be careful with their actions. While they're determined to take Marco down, one wrong move could lead this villain to unleash the protomolecule in a more devastating way. The Roci crew needs to reunite to stop this from happening, though this wouldn't be entirely easy.

Most of them were still separated from one another in The Expanse season 5 episode 5. For instance, James Holden (Steven Strait), Amos Burton (Wes Chatham), Alex Kamal (Cas Anvar), and Naomi Nagata (Dominique Tipper) have already been in different places.

Then current installment saw the crew being separated most of the time, which may continue moving forward. They recognized that they need to reunite to stop Marco once and for all. But before the reunion happens, the crew needs to deal with the challenges and chaos coming their way.

The Expanse season 5 episode 5 airs on Wednesday, Dec. 30, on Amazon Prime Video.
