Even though we wish we could have her back full-time, Calista Flockhart will be back as Cat Grant this season. Flockhart’s character will first be seen in the season premiere titled “Girl of Steel” and her return has been teased to be “very clever”.
But it sounds like we may get a little more of Cat this season compared to Supergirl Season 2. Flockhart is reportedly going to recur throughout the season. The last we saw of her was in the season 2 finale where viewers discovered that Cat knew about Kara’s super-secret.
