AVClub: Supergirl doesn’t need training. She’s got super strength, laser eyes, powerful lungs, and the ability to fly—what more could she need? A lot more, it turns out, when she tries to save an oil tanker from exploding but ends up creating a minor ecological disaster in the National City harbor. As her sister puts it, Kara has the strength but not the technique. So she decides to go back to basics and generate good will with small-scale heroism (robbery thwarting, ambulance transportation, snake rescues, etc.). By episode’s end Supergirl realizes that if she wants to be a proper hero, it’s going to take some time. The same can be said of Supergirl as well.
