In light of this weekend's terrorist attacks in Paris, which left communities worldwide mourning the loss of at least 132 lives, CBS has decided to pull the "Supergirl" episode the network had scheduled to air Monday. Instead, viewers will see a holiday-themed installment that had previously been slated for the following week.

"How Does She Do It?" the episode CBS opted against, was to see Kara defend National City from a series of bombings, but with real-life coordinated attacks on innocents dominating the headlines, CBS will instead air "Livewire," a Thanksgiving story featuring Helen Slater as Kara's foster mother that sees the introduction of Brit Morgan as a new supervillain. The switch was announced via press release, and though it made no mention of this weekend's events, a CBS source told TVLine that the scheduling decision came "out of sensitivity and respect to the events that occurred."

No replacement date for "How Does She Do It?" has yet been announced, whose original, official episode description read:

KARA IS PULLED IN OPPOSITE DIRECTIONS WHEN SHE BABYSITS CAT'S SON WHILE TRYING TO STOP A SERIES OF BOMBINGS, ON "SUPERGIRL," MONDAY, NOV. 16

"How Does She Do It?" - Kara's two identities are stretched thin when Supergirl must protect National City from a series of bombings and Kara is tasked with babysitting Cat's son, Carter. Also, James is conflicted when his ex-girlfriend Lucy Lane seeks to rekindle their relationship, on SUPERGIRL, Monday, Nov. 16 (8:00-9:00 PM, ET/PT) on the CBS Television Network. Levi Miller guest stars as Carter Grant, Cat's son, and Jenna Dewan-Tatum guest stars as Lucy Lane.

"Limewire," which replaces what was to be the fourth episode of the season, has the following description:

KARA'S THANKSGIVING MAY BE RUINED WHEN HER FOSTER MOTHER COMES FOR A TENSE VISIT AND A VOLATILE CATCO EMPLOYEE IS TRANSFORMED INTO THE VILLAINOUS LIVEWIRE, ON "SUPERGIRL," MONDAY, NOV. 16

"Livewire" - Kara's Thanksgiving may be ruined when she suspects her foster mother, Dr. Danvers (Helen Slater), who is coming to town, disapproves of her new role as a superhero. Also, when an accident transforms a volatile CatCo employee into the villainous Livewire, she targets Cat and Supergirl, on SUPERGIRL, Monday, Nov. 16 (8:00-9:00 PM, ET/PT) on the CBS Television Network. Brit Morgan guest stars as Leslie Willis/Livewire and Helen Slater guest stars as Dr. Eliza Danvers, Kara's foster mother.

CBS made another change to Monday's schedule, pulling an ISIS-themed episode of "NCIS: Los Angeles." Titled "Defectors," it will be replaced by "The Long Goodbye," which had been intended for December 7.

"Supergirl" airs Mondays at 8 p.m. Eastern, on CBS. In some languages, the "S" she bears on her chest means "Hope."
