Kara and Lena’s new dynamic will cause some tension between them.

At the end of the Season 3 premiere of CW’s “Supergirl,” Lena (Katie McGrath) decided to buy CatCo Worldwide Media after finding out that ruthless real-estate developer Morgan Edge (Adrian Pasdar) was planning to take over the company and use it to advance his interests. With Lena’s acquisition of the media conglomerate, the L-Corp CEO is now Kara’s (Melissa Benoist) new boss. While that means more interactions between the two characters moving forward, Lena and Kara’s new dynamic as boss and employee is going to put their friendship to test.

“Well, there’s going to be some bumps, which we really like,” executive producer Andrew Kreisberg told Comic Book Resources of how Lena and Kara’s new dynamic will impact their relationship. “I mean, there’s a great line in episode 2, where Kara says, ‘I’m not used to having my friend be my boss,’ and Lena says, ‘Well, I’m not used to having friends.’ It’s going to take a little bit of time for them to settle into those roles.”

While it remains to be seen whether Lena and Kara’s new roles will break or make their friendship, Kreisberg said that the little conflict between the two is part of the show’s plan to “see the relationship between all of these women and this sort of group of friends [develop].” “Kara and Alex (Chyler Leigh) are obviously sisters and best friends, but how Lena fits into that and how Sam (Odette Annable) fits into that?” Kreisberg teased. “Watching them grow closer and, at times, apart, it’s a primary focus of Season 3.”

Meanwhile, McGrath couldn’t be more thrilled with the CatCo twist, as it allows her to get to work with more of the cast than last season. “It’s funny because when we were at [San Diego] Comic-Con, the No. 1 thing I was asked was what I would like for the next season, and I always said I’d like to find a way — this is actually before I even read the scripts — for her to interact with the rest of the cast, because my storyline was very Kara-dependent, which was great, but you can’t maintain that for more than one season,” McGrath told Entertainment Weekly. “It’s nice now to be in situations and dealing with new characters. What they’ve managed to do this season, which is amazing, is to make it more ensemble. Everyone’s storylines are all interconnected.”

“Supergirl” Season 3, episode 2, titled “Triggers,” airs on Monday, Oct. 16 at 8 p.m. EDT on The CW.
