Earlier this month it was announced that Azie Tesfai, who plays James Olsen's sister Kelly on The CW's Supergirl,will co-write the twelfth episode of the series' sixth and final season expected sometime later this year. It's the first time an Arrowverse actor has written an episode of their own series and with Arrow star David Ramsey directing, it's something of an Arrowverse family affair. Now, Tesfai is opening up about the experience and says that the episode is "epic" for her character while also teasing big things for the season overall.
