Lex Luthor is coming to Supergirl, and the longtime Superman villain is out to reunite with his younger sister, Lena.

The CW has released official stills from the DCTV series' upcoming 15th episode of its fourth season. Titled "Oh Brother, Where Art Thou?," the episode has guest star Jon Cryer's Lex Luthor furloughed from prison due to his failing health. Under the supervision of the Department of Corrections, Lex travels to National City to speak with his sister Lena to help him find a cure for his ailment and save his life.

While a suspicious Lena contends with her brother, Jimmy Olsen has a family reunion of his own with his sister, Kelly (guest star Azie Tesfai). Supergirl and Martian Manhunter confront Manchester Black over his unchecked, out of control vigilantism.

The episode is written by Derek Simon and Nicki Holcomb, and is directed by Tawnia McKiernan. The episode is scheduled to air on Sunday, Mar. 17.
