Supergirl, Season 5

Alex:
You know, I, um... I-I realized that my spiral this morning about the blueberries wasn't... wasn't really about the blueberries.

Kelly:
What do you mean?

Alex:
We haven't been together for very long, so, you know, it just made me realize how much we still don't know about each other. And, you know, I really frickin' like you, like, a lot. And so... that scared me.

Kelly:
Alex, you're safe with me.

Alex:
I know that now. Earlier when I... when I touched her hand, I knew that wasn't you. Because you can't fake how that feels. Just like you can't fake being who you are. So, on that rooftop, when you made that very selfless choice, I knew exactly in that moment which one of you was my Kelly. And I might not know every little detail about you yet, but I know you.
