On this week's podcast, Ars Technica's Jonathan Gitlin talks with actor Wes Chatham about his character Amos on The Expanse. Wes talks about being a fan of the books before being offered the role on the show, how he approaches this unusual character, and the discussion veers off into Blade Runner territory (which version is Wes' favorite?). Jonathan also recaps season 2, episode 9: the Roci crew commandeer a ship to Ganymede, Bobbi Draper takes her first trip to Earth to be grilled during the UN/Mars peace talks, and a crew travels to Mars to find out what happened to Eros.
