According to The Hollywood Reporter, Baccarin who has been guesting as Dr.Thomkins since last week's episode was brought on board with an option to become a regular member of the cast if the series gets a second season. Asked what she thinks of the possibility, the star of such cult favorites as Homeland, Firefly, and V, said: "I was excited by the possibility. I feel like, it's one of those things that you have to wait and see how it works. You bring on any major new character, and you have to see how all the moving parts and going to hold together. But I think there's a lot of possibility for her to stick around for a bit." Incidentally, Baccarin is also already on another DC Comics-based TV series. She is the voice of Gideon, Dr. Wells computer at STAR Labs in The Flash.
