The second episode will find Kara fighting another escapee, Hellgrammite, from the Kryptonian prison, while seeking James Olson and Winslow Schott's help. A sneak peek shows James Olsen and Schott together in a secret area. When Supergirl appears they awkwardly greet each not knowing if the other knows about her. Then they both look at Kara and ask in unison, "He knows?" Supergirl replies, "James already knew, and Winn is my friend."

She explains, "If I am going to be a hero, and prove to everyone that I know what I am doing, I need to practice. Start small, get better. And to do that I need your help." Olsen and Schott both agree to help. Fans should watch out for a love triangle involving the three of them in upcoming episodes.

Another promo shows Hank Henshaw testing Supergirl's abilities in a series of tests. Kara begins to ask if the tests are mandatory for everyone. Henshaw cuts her off and says, "Not because you are a woman, Miss Danver. The DEO [Department Of Extra-normal Operations] requires rigorous physical and psychological evaluation for all our respective field officers."

He says superheroes can turn out to be liabilities sometimes, and he needs to know if they actually are in full control of their powers, stamina, strength and speed. We then see Kara flying faster than speed and Alex exclaiming, "My sister just broke the sound barrier!"
