On this week's podcast, Ars Technica's Jonathan Gitlin is joined by linguist Nick Farmer who created the spoken language of Belter for The Expanse. Last year, Nick was our first Ars Live guest at Oakland's Longitude bar, and he's back to speak with us one-on-one. Jonathan also recaps season 2, episode 7: as the UN leaders argue about what to do about Mars, the Roci crew helps refugees from Ganymede on Ceres, Bobbi Draper tries to recall what happened to her crew, and Anderson Dawes challenges Fred Johnson's leadership.
