Supergirl, Season 4

Lena:
I'm sorry I was so short with you. You were just trying to do your job.

Kara:
Friendship is the most important job, and I was so focused on my article, I forgot what really matters.

Lena:
No, Kara. The truth is, even if you'd been standing right next to me when Lex escaped, I really wouldn't have let you be there for me.

Kara:
What do you mean? Why?

Lena:
Because I'm the one that's keeping secrets. Eve wasn't the only one working with Lex. I... [her emotions begin to overwhelm her] I was working with him, too. He contacted me four months ago. He knew I had the Harun-El. He had cancer and he was afraid to die. He's my brother. And in my heart, I knew he was manipulating me, but I believed him, and I helped him and he betrayed me. And I was weak, and I will never forgive myself for that. I can only imagine what you think of me, Kara. I don't blame you.

Kara:
[hugging her as Lena cries] No, no. You are not weak. You are a brilliant, kind-hearted, beautiful soul. Your brother asked you for help, and in life and death situations, you help family. No one can judge you for that. I'm so sorry you felt like you couldn't tell me.
