"The Expanse" is on Amazon Prime Video right now and you should watch it immediately. If you don't stop for sleep or sustenance, you might just make it before the end of the series.

The actors of "The Expanse" talked to Space.com.

The drummer is a serious character. She had her spine crushed while commanding the OPA Behemoth during the Slow Zone incident and she had to deal with the death of her friend and mentor. The wind out of your sails will be taken out by either of those two things. She is riding the storm with the wind at her back. How does she prepare for the change from reality to role?

She says she dives into the drummer first every chance she gets. It is a gift to be able to transform so completely, because they give us these brilliant words to say and her voice and makeup.

From the moment she joined "The Expanse" back in February of last year, Camina Drummer made an impact.

Alexander's role is not a picnic. To deliver a performance as convincing as Alexander has, you have to wonder if it's difficult to let go once you're in that space.

I feel like I'm still deconstructing some of the ways that he's intertwined with me. He is obviously there. Alexander bristled when people used the word "evil", because it made him feel like the traps of narcissism and the extents to which the ego will go if it's not restrained in all of us. It has been an interesting process to step away from him.

The sixth and final season picks up with the solar system engaged in all-out war, as Marco Inaros continues to launch devastating asteroid attacks on Earth and Mars. Both Alexander and Gee joined the story after it was already airing on syfy, the former in "Doors & Corners" and the latter in "Retrograde" in 2019. They must have taken something from the show to remember the experience.

Alexander said to Gee, "You can tell them..." She took Marco's underwear. She freed Marco's underwear.

If you want to hear more about that story, you need to watch the video above.

Amazon saved 'The Expanse'.

Marco's appearance in late 2019? sent shockwaves through the Solar System.

It's sad to think that the show is coming to an end, but we will get to see Naomi Nagata, Jim Holden, Amos Burton, and Clarissa Mao.

Maybe it's time to re-watch a series.

Amazon Prime Video is ending this season. The events in book 6 are brought to us by the authors Daniel Abraham and Ty Franck. There is a 28-year gap between the events of "Persepolis Rising" and "Babylon's Ashes" so this seems like a natural place to break. "Leviathan Falls" is the ninth novel in the series.

The season consists of just six episodes. The sixth and final episode is on Amazon Prime TV.
