The Test

Lex Luthor has had enough. He wants to reveal Supergirl for the incompetent attention whore that she really is. He's tired of people elevating her when he knows she's no hero. He sets up a series of tests coinciding with three bombs. He hires a thug to coerce her to a predetermined location, and once there, he rolls cameras for the populous to finally see the truth. He spares no mercy while humiliating and torturing Supergirl and breaking her body and her will, demonstrating to the world that she is not the hero she claims to be. Torturing her will and ending her sanctimonious life is far more enjoyable.
