The season-long plot nears its conclusion—but this is “Discovery,” so there’s still time for a heart-to-heart while wearing Breen helmets. Jason and Scott have an oil bath to get to, but before they do, they break down the penultimate episode! Saru’s back! Vulcan flower holders! And the most dramatic scene of a man sitting in a chair that we’ve seen in years. Scott McNulty and Jason Snell.
