Kara: You spent years trying to be open and trusting. Even when everyone expected you to be like your family. Even when everyone in your life let you down. Even when I was weak and lied to you knowing that all you ever asked for was the truth. You were always better. Lex took advantage of my weakness and used it to manipulate you. He wanted my mistakes to change you. He wanted you to become him. But, you are nothing like him. Nothing. Don't let my mistakes turn you into something you're not. Lena: I am good. And I always was. Lex didn't change me and you didn't change me either. You just exposed me to the ugliness of humanity. You did me a favor Kara. I learned what kind of deceitful person you really are and that's what inspired me to do this.
Alex: Your choice to conceal your identity wasn't born out of a place of maliciousness. It was born out of love and compassion. You were just trying to protect your family and you were trying to protect Lena from people who could use that information to hurt us. And look, I love Lena too. I am deeply upset by what's going on. But, this isn't just two friends who are in a fight, this is someone who has turned a corner. Kara: No, this is not her, this is not our Lena. Alex: Well who is our Lena? I mean, she knew that Lex was out of prison and she said nothing. She kept Sam Arias locked in a sub-basement at L Corp knowing that she was Reign and she said nothing. She knows how to make kryptonite and she kept that hidden from us. Lena is leading her own double life. Kara: You are making her sound like a Luthor. Alex: Maybe that's because she is one. We can't put our faith in some distant hope that she is going to do the right thing. And, when every single action that she has taken up until now points to the contrary. Okay, we have to stop her Kara. The safety of the world depends on that. Kara: She is not Lex. I will not treat her like a villain. Alex: I know you won't. That's why I have to.
