A lot of fans love the addition of Lena Luthor (Katie McGrath) in Season 2 of Supergirl. In part, she replaced Maxwell Lord (Peter Facinelli) and gave Kara Danvers (Melissa Benoist) a best friend. And while some folks even began shipping the pair — coming up with the ship name of SuperCorp — a lot of people were watching closely to see just when she would turn evil. She is a Luthor, after all, and the episode where they showed how she joined the family demonstrated how she is more intelligent than her half-brother Lex.
If it's going to happen, don't expect it to be like a light switch. She won't go from being a good person to suddenly evil in the blink of an eye. It will be more gradual, as executive producer Andrew Kreisburg explained to EW.com:
"Lena and Kara's friendship will continue to grow. There's a lot of Lena-Kara adventures early on in this season. The most interesting thing about Lena is that she is so good, and so moral, and believes in second chances, but she comes from this family of truly evil people. As people are going to realize over the course of this season, it doesn't take much to make you bad. People don't just turn evil. They do one small bad thing and then that leads to another, and then to another, and so any time you're watching Lena, you're always wondering, 'Is this the moment when she does the one small thing?'"
One, small evil thing. When will it happen? Or has it happened already but it was so small and evil that we missed it? Maybe she illegally parked and now it's all down hill from here. The bad apple doesn't fall far from the Luthor tree. Kreisberg makes it sound like it's a matter of when, not if.
Supergirl Season 3 will debut on Monday, October 9th at 8 p.m. ET on the CW.
