Alex: Give me the device.
Lena: Alex, I hear what you’re saying, but I have to bring Kara back. You see, it’s my fault. It was my brother who sent her to the Phantom Zone. It was my experiments that empowered him. It was my war with Supergirl that started all of this. So if this is my only chance to make it right, then I have to do it.
Alex: Okay, Lena, listen to me. Nobody blames you for this. Kara doesn’t blame you for this. You two already forgave each other for everything that happened in the past. So it’s time for you to forgive yourself. And all that really matters is that you do the right thing today.
