Warehouse 13

LIE TO ME (Monday, 9/8c, Fox)
It's a mini-Shield reunion when a half-dozen former cast members appear in guest roles—an homage courtesy of Shawn Ryan, who created The Shield and is show-runner for Lie's summer season. Look for David Rees Snell, David Marciano, Catherine Dent, Benito Martinez, Cathy Cahlin Ryan and Kenneth Johnson in this episode, which finds Lightman and ex-wife Zoe witnessing an execution and wondering if they sent the wrong person to Death Row.

WAREHOUSE 13 (Tuesday, 9/8c, Syfy)
A bionic treat awaits fans of this fantasy adventure, as former Bionic Woman Lindsay Wagner guests as the Warehouse's in-house doctor, who looks after team members as well as the Regents governing body. In this episode, she's called in when Artie gets sick while Myka and Claudia investigate puzzling deaths on a college wrestling team.

SOUTH PACIFIC (Wednesday, 8/7c, PBS; times may vary)
The Tony-winning Broadway revival airs Live From Lincoln Center, with Kelli O'Hara and Paulo Szot returning to the tuneful and timelessly topical Rodgers & Hammerstein classic as Nellie Forbush and Emile de Becque. (Trivia note: Glee's Matthew Morrison was the production's original Lt. Cable.) At home, you're allowed to sing along—because the score is bursting with standards.

CSI (Thursday, 9/8c, CBS)
This repeat of an enjoyably change-of-pace episode, focused on lab rats Hodges and Wendy (and co-written by Wallace Langham and Liz Vassey), finds the CSI techs leading a group of high-school CSI Explorer Scouts (including High School Musical's Lucas Grabeel) on a field trip where things get out of hand. It's one of your chances to enjoy Vassey, who's leaving the show next season.
