Fresh off the “Better Call Saul” series finale, Rhea Seehorn joins us to delve into the show’s last twists and turns and to give insight into her Emmy-nominated portrayal of ethically flexible attorney Kim Wexler.If Kim and Bob Odenkirk’s Jimmy McGill character were to get a do-over, how far back in time would they have to travel to put themselves on track for a happily-ever-after? Probably all the way back to the beginning of the series, when they worked together in the mailroom, Seehorn muses. “They would go out with each other, fall in love and then get really, really great therapists.”In this episode of “The Envelope,” she also discusses her efforts to balance gratitude with confidence in her skills, how her father’s alcoholism shaped her as an actor and the scariest day on the “Better Call Saul” set: when Odenkirk suffered a heart attack right in front of her. To read a full transcript of this interview, please visit the episode page at latimes.com.
