SUPERGIRL
CBS, 8:00 p.m. ET
It’s established, thanks to last week’s episode, that the main villain in Season 1 will be played by Laura Benanti, who appeared in the premiere episode as the doomed Kryptonian mother of Melissa Benoist’s emergent Supergirl. That’s possible because Benanti is playing not only Supergirl’s late mother (and continuing to play her, in pre-recorded holograms from outer space), but the mother’s evil twin sister. How did alien auntie survive the explosion of Krypton? She was one of the villains banished to the inter-dimensional limbo of the Phantom Zone – and, like other Zone prisoners, now arrived on Earth to wreak havoc. Or, at least, to congregate while deciding how best to wreak.
