The CW has released the promo photos for Supergirl episode 4.18, titled “Crime and Punishment,” featuring our titular heroine and Lena working together as they try find clues on how to defeat Lex Luthor. The new episode is scheduled to air on April 21. Check out the full photos below!

The episode is directed by Antonio Negret from a story written by Rob Wright and teleplay co-penned by Lindsay Sturman and Aadrita Mukerji. Its official synopsis reads:

“WILLIE GARSON GUEST STARS – Supergirl (Melissa Benoist) and Lena (Katie McGrath) head to Stryker’s Island to search for clues on how to defeat Lex. At the prison, Supergirl tries to befriend a nosy prisoner, Steve (guest star Willie Garson), who may have insight into what Lex was doing, but he and all of the prisoners regard her as a traitor to the country and refuse to talk to her. Lena realizes Lex left behind clues for her and deciphering them could be the key to his whereabouts. Meanwhile, Kelly (guest star Azie Tesfai) encourages James (Mehcad Brooks) to talk to someone about his PTSD, and Alex (Chyler Leigh) faces off against Ben Lockwood (Sam Witwer) after he storms the DEO and acquires some powerful weapons to hunt Supergirl.”
