Kara and Mon-El have more to worry about than just a malicious alien in a sneak peek from Monday's midseason premiere of "Supergirl."
In the sneak peek, Chris Wood's Mon-El has followed Melissa Benoist's Supergirl through a portal to Slaver's Moon. However, he quickly learns from a bleeding Kara that the planet has a red sun, like their native Krypton and Daxam, which means the two superheroes no longer have powers. The obvious solution would be to immediately exit Slaver's Moon the same way they came, but the pesky portal doesn't want to cooperate.
Kara (Melissa Benoist) is moved by the story of a missing woman named Izzy (guest star Harley Quinn Smith) and decides to investigate despite Snapper Carr’s (guest star Ian Gomez) order to leave it alone. Kara takes Mon-El (Chris Wood) with her to the last place Izzy was seen and the duo find themselves thrust through a portal to another planet, Slaver’s Moon, where the downtrodden are sold as slaves. The leader of the trafficking ring is none other than Roulette (guest star Dichen Lachman). To make matters worse, Slaver’s Moon has a red sun, which means Kara and Mon-El are stripped of their powers and stuck on the planet with no way home. Meanwhile, back on Earth, Alex (Chyler Leigh) blames herself for Kara’s disappearance, fearing she’s become too focused on her new relationship with Maggie (guest star Floriana Lima) and too complacent in watching out for her sister.
Directed by Kevin Smith, "Supergirl Lives" features guest stars Ian Gomez as Snapper Carr, Harley Quinn Smith as Izzy, Dichen Lachman as Roulette, Floriana Lima as Maggie Sawyer and Brit Morgan as Livewire.
Airing Mondays at 8 p.m. ET/PT on The CW, "Supergirl" stars Melissa Benoist, Mehcad Brooks, Chyler Leigh, Jeremy Jordan, David Harewood and Chris Wood.
