The excellent on-screen chemistry between Ms. McGrath and Melissa Benoist has led to some fans reading their friendship as a romantic one.  The people involved in making the show do seem to be aware of how strongly fans feel about the Kara/Lena relationship, too. “I’m pretty sure the producers weren’t expecting this, as I wasn’t [originally] signed for that many episodes, but here I am,” Ms. McGrath says. “What’s nice is that they’ve responded not only to how Melissa and I are together but also to how the fans like it. They’re very intuitive and very involved with the feedback and what they see online. They’re responding to something, so here we still are!” Supergirl Season 3 premieres on October 9.
