Preview Clips for Tonight’s New Episode of “Supergirl” Season 4 Finale “The Quest for Peace”

The 22nd and final episode of Season 4 of “Supergirl” will air tonight.

The CW has released two preview clips for this episode…

Jon Cryer spoke to about a scene in tonight’s episode in which Lex has a family reunion with his mother Lillian and sister Lena… in the oval office…

“It feels like those awfully tense scenes that all families go through, except one of them is maybe about to be a mass murderer,” jokes Cryer, adding that the finale paints Lex as “a lethal manipulator of human emotions. The stuff he does to both Red Daughter and his family members is just remarkable. He should give a TED talk. It’s kind of jaw-droppingly evil, and it’s of the things I was really excited about doing he’s hard to top. He has a history of being evil in pretty grand ways, but it’s the little interpersonal evil this finale reveals.”

Titled “The Quest for Peace” this episode is scheduled to air on The CW in the USA on Sunday, May 19 at 8.00pm ET/PT.


Lex Luthor (guest star Jon Cryer) descends upon Washington, DC and summons Lena (Katie McGrath) and Lillian Luthor (guest star Brenda Strong) to the White House. Supergirl (Melissa Benoist) realizes she has one last chance to stop Lex and turns to the power of the press to help her.

Jesse Warn directed the episode with story by Robert Rovner and Jessica Queller and teleplay by Rob Wright and Derek Simon.
