“Infested,” directed by Saul Ruiz and written by Amanda Rose Muñoz, explores the Bad Batch’s criminal underworld home base in an inconsequential but competent episode. Cid (Rhea Perlman) gets a well-deserved stint as a main character in an adventure that feels like a side plot, with choppy bursts of classic Star Wars action not really adding much to the story of the clones as clones. While not every story can be (or should be) as hooked in to the rest of the franchise as Hera’s was last week, “Infested” left the Bad Batch feeling more generic than when it started.

What actually happens is that the clones return “home” to discover that their benefactor/client Cid has been deposed. In her spot sits Roland Durand, the original owner of the pet lizard the gang recovered in a brief intro earlier in the season. He’s a gang member trying to live up to the criminal aspirations of his mother, starting with taking over Cid’s place. What follows is a twisting plan to get the cantina back, involving an expedition into a mine filled with deadly insects who don’t like visitors.
