Nellie Andreeva for deadline.com

Lena Luthor will be sticking around. Katie McGrath, who has recurred on Supergirl this season, has been made a regular for the upcoming Season 3, which was recently picked up by the CW. McGrath plays vixen Lena Luthor, the baby sister of Lex Luthor, who came to National City to get out from under the shadow of her notorious brother.

This is good news. I think she's been a great addition to the cast.
