CBS has decided to air a different episode of Supergirl on Monday, Nov. 16, because the storyline was too close to the terrorist attacks in Paris.
The episode originally scheduled for Monday had Kara dealing with a series of bombings in National City. According to Variety, the swapped-in episode is called 'Livewire', and it revolves around Kara's relationship with her foster mother, played by Helen Slater (who played Supergirl in the 1984 feature film).
