Supergirl, Season 3

Maggie:
Are you sure you want to give up on this? Sure you want to do this, give up on something tangible and real? Some... us, it's us. For some notion of being a mom?

Alex:
It's not some notion. Ever since I was little, when I would see a mom and her kids, this thing would happen to me, this recognition that I would be a mom too. And it wasn't some you know... "I want that" or "I hope someday that I have that". It's just something that I've always known. Even when everything else, when it was boyfriend, girlfriend, whatever, when that was blurry... The part of me being a mom, that's always been crystal clear. And if I deny that, I'm gonna feel it forever. I wish I could change the way I feel, but I can't.
