1) “Cupertino,” 10 p.m., CBS. Last week, we started to meet Bo, who insisted (to a skeptical response) that he’s an AI creation, wanting guardrails. We also met the law firm’s potential investor (Busy Phillips, shown here). Today, she nudges the firm toward a personal case. That one is fairly interesting, but the ongoing story of Bo — one of TV’s best characters — is fascinating.
2) “9-1-1,” 8 p.m., ABC. It’s tough to shrug off a sinkhole, when it gobbles neighborhoods and sparks a volcano. Now that crisis continues; as lava spreads, squads try to rescue trapped and frightened people.
3) “Grey’s Anatomy,” 10 p.m.,, ABC. This hospital show suddenly has a college storyline. Bailey (Chandra Wilson, 57) is back in school to study public health; administration. Soon, she and Blue confront a crisis, involving fraternity hazing.
4) “Eternally Yours” and “Elsbeth,” 8:30 and 9 p.m., CBS. Two popular supporting actors have guest roles. First, it’s Jeff Hiller, the towering (6-foot-5) Emmy-winner from “Somebody, Somewhere”; he plays a vampire official, wary of the new initiate. Then it’s Christine Ebersole, who was great as Bob’s mom in “Bob (Hearts) Abishola”; now she’s Elsbeth’s mom.
5) ALSO: A week from its season-finale, “American Horror Story” (9 p..m, FX) finds the coven approached by a handsome stranger; another episode, at 9:44, finds the Coven bracing for its toughest foe yet. And the “Family Guy” marathon (7 p.m. to midnight, FXX) includes an hourlong episode at 8, with a re-telling of “Return of the Jedi.”
