Supergirl Season 2 Episode 20 “City of Lost Children” Promo

Here is the promo for the 20th installment of Supergirl season 2 titled “City of Lost Children”. In this episode of Supergirl, Lonnie Chavis guest stars.

When an alien attacks National City, Supergirl (Melissa Benoist) and the DEO learn the alien is a Phorian, an otherwise peaceful race with telekinetic powers. Guardian (Mehcad Brooks) gets a lead on the Phorian’s address but instead of finding the culprit, he finds a very scared boy named Marcus (guest star Lonnie Chavis). Marcus will only trust James so it is up to Guardian to stop the attacks on the city. Rhea’s (Teri Hatcher) plan escalates.

Supergirl “City of Lost Children” airs on May 8 at 8|7c on The CW.
