The CW has released the official description for the 12th episode of Season 3 of “Supergirl”.

Titled “For Good”, this episode is scheduled to air on The CW in the USA on Monday, January 29 at 8.00pm ET/PT.


Someone tries to kill Morgan Edge (guest star Adrian Pasdar) and he barely survives. He accuses Lena (Katie McGrath) of being behind the attempt and vows to destroy her. When Lena fears her hatred for Morgan will take her to the Luthor dark side, Kara (Melissa Benoist) steps in to help her friend. Meanwhile, after Sam (Odette Annable) realizes she’s losing time, she confides in Alex (Chyler Leigh) who decides to run some medical tests to see if she can find out what’s going on with her new friend.

Tawnia McKiernan directed the episode with story by Robert Rovner and teleplay by Cindy Lichtman and Alix Sternberg.

I’m glad that Lena will have an episode. Time will tell if she will follow in her brother’s foot steps. I’m hoping she stays good.

The same here. But this Edge/Luthor war is getting tiresome.

If she goes bad then she’s just reduced to being Rule 63 Lex IMO.
