Supergirl Season 2 Episode 20
City of Lost Children
When an alien attacks National City, Supergirl and the DEO learn the alien is a Phorian, an otherwise peaceful race with telekinetic powers. Guardian gets a lead on the Phorian's address but instead of finding the culprit, he finds a very scared boy named Marcus. Marcus will only trust James so it is up to Guardian to stop the attacks on the city. Rhea's plan escalates.
