KREISBERG: We don’t want to say too much because we’re doing our own version of Mon-El. Obviously, he’s a character from the comic books and he’s much beloved, and we’re putting our own spin on it. What’s interesting about Mon-El joining the show, from Kara’s perspective, is that Kara has spent her whole life as someone who’s been mentored, first by her mother, and then by the Danvers and Superman and Cat. She’s always been somebody who’s been taken care of, in a way. Now, with Mon-El, he’s fresh off the boat. As far as he’s concerned, living on another planet happened yesterday, and suddenly, he’s on Earth and everything he knew was lost, just the way it was for Kara, but she’s had 12 years to process it and he’s struggling with it. So, Kara is now the one in the mentor position. Ironically, she even says in an episode, “I was sent to Earth not to be a hero. I wasn’t sent here to be Supergirl. I was sent here to protect Clark and take care of Clark. Now, in an odd way, with Mon-El here, I’m getting to fulfill that original mission that I had.” So, it’s a big change and a big growing experience for Kara, this season
