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.
