The bulk of shooting on the fifth season of Amazon’s “The Expanse” has wrapped with the crew gathering earlier this month to celebrate the end of work.

Photos from the wrap party and from the cast and crew in recent weeks have hinted at some things to come, from the rise of Keon Alexander’s Marcos Inaros (and his son played by Jasai Chase Owens) as a major threat, to the return of basically all the major cast across the season. Check out Newsweek.com for pictures (WARNING: SPOILERS).

The fifth season is based primarily on “Nemesis Games,” the fifth novel in the series by Daniel Abraham and Ty Franck (penned under the name James S.A. Corey) and an entry considered one of its best. Solar system politics come back heavily into play next season, along with an even more ambitious scale and actions that will have major consequences.

Actor Wes Chatham said on Instagram he’s seen half of the season so far and “it is hands down the best thing we have ever done. It blew me away”. The fifth season doesn’t have a release date, but will likely to premiere on Amazon Prime around year’s end. No word as yet on a sixth season renewal though signs are good.
