"I don't... know... how to fight this one. And I should be able to stop her, but—but then she makes her way into my mind and... and forces me to relive the scariest moment of my life. It's... it's torture. How am I supposed to deal with that?"
"Well, by remembering that... your fears don't define you. You know who you are is Supergirl. Who you are is Kara.
