Supergirl and Steel in “Unfinished Business”

Supergirl

I'm worried about them, Steel. I'm worried about my cousin.

Don't be. Everybody in the League is good at their job, but those seven? They're the best ever. Not because they're the most powerful - they aren't. Not all of them. And it's not just because they were the first. It's because they're special. They've proven it time and again. They make the hard choices, they set the example. They do what's right, not what's easiest. And they always come out on top. They're gonna be okay, Kara. We all are.
