Warning: This article contains major spoilers about season 4 ofThe Expanse.
That meant the earlier introduction of a key villain from book 5, Marco Inaros.
Naomi’s former lover, and the father of her child, Filip.

And you do that only to then make us later mourn his death.
Why decide to kill off that character and make him one of Marco’s early victims?
Yeah, I’m just glad it worked out the way it did.

You end the season by sending that giant rock hurtling towards Earth.
Can we expect a similar result from what happens in the book?
Here, we also get to see really what stealth technology is.

We talked about it for years.
That’s a serious thing.
Now we see why it’s so serious.
You extended Ashford past where we saw him in the books, so what about Murtry?
Is his story on the show complete and is this the last we’ll be seeing of that character?
Yeah, Murtry was always that way.
He’s certainly in the world, so who knows?
You never know who’s out there.
And is this the end of Miller (Thomas Jane)?
“This is the end for me.”
Now, the protomolecule is a hive mind.
It’s like one part of it communicates with all other parts of it.
Does that mean there’s no Miller at all left period?
I don’t know.
You talked about bridging into season 5.
I have to assume that’s going to be a major story moving forward, right?
It certainly is setting up that way, without question.
And that’s a big deal.
It’s interesting because you show how fractured parts of the OPA are here in season 4.
What does that mean for the OPA moving forward as Marco’s plan is carried out?
Well, it’s a fundamental problem with how they’re trying to form a government.
It’s hard to unify that kind of a group.
A big part of Amos' story in book 5 takes place on Earth.
Will we see any of that in season 5 or do you have different plans for Amos?
That storyline is continuing.
Holden’s had this thing in his head, and it looks like it is finally out.
What does this mean now for that character moving ahead?
He’s been hanging on to this for a long time.
So, it is a good question: What is Holden’s next step?
What Holden and his guys have proven is that these worlds are safe, right?
Well, they’re safe so long as there’s no protomolecule to turn things on.
