Levi Miller plays Carter Grant, Cat Grant's son, in a new clip from "How Does She Do It?", the next episode of "Supergirl." Kara keeps an eye on him as he hangs out by his mother's office, and he expresses some strong feelings for Supergirl -- which her best friend Winn (Jeremy Jordan) mirrors.

"Supergirl" airs Mondays at 8 pm EST on CBS. Developed by producers Greg Berlanti, Ali Adler and Andrew Kreisberg, the series stars Melissa Benoist, Calista Flockhart, David Harewood and Chyler Leigh.
