Warning: Storyline and character spoilers ahead for the “Nailed” episode of Better Call Saul. This penultimate episode of Better Call Saul’s second season would have made for a fine, cliffhanger finale, but the primetime gods have smiled upon fans and we’ll have one more Season 2 installment to further the major storylines that ramped up in “Nailed.” BCS co-creator and showrunner Peter Gould, who wrote and directed “Nailed,” talks to Yahoo TV about Chuck McGill’s very serious accident — which made one of the most cringe-inducing sounds we’ve ever heard, how Chuck has become a more sympathetic character this season, and how Mike Ehrmantraut’s happy day turned so ugly, so fast. Gould also chats about Mike’s “low-tech” formidable skills, how Kim has been brought down to Jimmy’s level in the Mesa Verde saga, and offers this preview of the season ender: “I think you’re going to see some sides of Jimmy and the other characters that you haven’t seen before.” I am haunted by the sound we hear at the end of this episode, poor Chuck’s head hitting that counter.
