Supergirl, Season 2

Eliza:
[comes to Alex who is working on the computer] So, what is it?

Alex:
I've got the mainframe breaking down the virus on a molecular level.

Eliza:
No, I mean I know you've been trying to tell me something.

Alex:
Oh, no. No. [collects herself] How?

Eliza:
Keeping a secret disagrees with you, sweetie.

Alex:
This isn't like that, Mom.

Eliza:
Does it have anything to do with Maggie? You mention her a lot. Oh, my beautiful Alexandra, why is it so hard for you to tell me?

Alex:
I feel like I'm... letting you down. Somehow.

Eliza:
Why would your being gay ever let me down?

Alex:
You always wanted me to have a regular life.

Eliza:
Alex, look at the life our family has led. Look at me, look at your sister. I don't think you believed that I ever expected you to have a regular life. You were always gonna be different, Alex, because you were always exceptional, and I love you however you are. Come here! [hugs Alex]
