In a new clip from "How Does She Do It?", this week's episode of "Supergirl," Kara accuses Hank Henshaw of spying on her with an advanced drone, only to find out there's another culprit behind it (via ComicBook.com). Alex determines that the technology is definitely human in origin, which means someone is on to Supergirl. The episode was originally scheduled to run last week, though CBS shifted the episode order out of respect to the Paris terrorist attacks.

"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.
