The Supergirl premiere found Kara Zor-El taking her first flight. After a great deal of self-doubt, she embraces her powers and becomes the superhero she is destined to become. Although her confidence is low when she starts off, a new threat forces her to push her doubts aside in episode 2 titled Stronger Together.
According to the synopsis for the upcoming episode, Kara will face another prisoner from the Kryptonian jail. "When Kara's attempts to help National City doesn't go according to plan, she must put aside the doubts that she - and the city's media - has about her abilities in order to capture an escapee from the Kryptonian prison, Fort Rozz."
Other than Hank Henshaw (head of a secret agency) only a few people who know Kara's real identity are - her sister Alex, and her co-workers Winslow "Winn" Schott and James Olsen. In the upcoming episode, Kara's boss Cat Grant will pressure James to use his connection with Superman to get her an interview with Supergirl.
The premiere episode revealed that when Kara crash-landed on earth from the Phantom Zone, it also brought along a Kryptonian maximum security prison full of criminals who are now looking to seek vengeance on Supergirl, as her mother was the one who imprisoned them. The episode ended with a twist - it turns out that her mother's twin sister Astra (Laura Benanti) is the leader of all the villains, and is hell-bent on ruling Earth and making Kara pay for the sins of her mother.
Executive producer Andrew Kreisberg talks about adding the new villainous twist to the classic DC Comics tale. He told Entertainment Weekly, "Her name is Astra. She's a character that we've created for the show, who doesn't come from the comics. On all the other shows, whenever the big bad has been personally tied to the hero, it's always been that much more evocative — certainly you look at Slade Wilson (Manu Bennett) and Malcolm Merlyn (John Barrowman), and, in a lot of ways, Harrison Wells (Tom Cavanagh). We thought it was really exciting that the villain be part of Kara's family that Kara thought was dead. "
The producer also explained that fighting Astra, her mother's twin sister, will be more emotional for the new superhero. "Even though it's not her mother, the big bad of the year wears her mother's face. That's certainly going to create emotional issues for Kara when she's placed in situations where, perhaps to save Earth, she's going to have to end her aunt's life."
Supergirl moves to its regular time period, for its second episode airing next Monday, 2 November at 8pm ET/PT on the CBS Network.
