Melissa Benoist Teases Reign's Transformation on 'Supergirl' Tonight

Supergirl battles it out with Reign in the middle of the street in this new still from tonight’s all-new Supergirl.

Melissa Benoist teased how the dynamic between the heroine and villain would be like with TVLine.

“I think Reign is going to surprise people,” she shared. “She’s pretty spectacular to behold, and she will give Supergirl the fight of her life. What sets her aside from the Big Bads that we’ve seen up to this point on the show [is that] she has a really surprising back story that gets you really invested in who she really is fundamentally.”

And remember, Sam (Odette Annable) isn’t just Reign aka the Big Bad…she’s also Kara’s friend!

“You see how close Kara, Sam and Lena are getting, I can’t imagine that it isn’t going to become difficult with Sam essentially being Supergirl’s arch-enemy and all three of us being friends,” Katie McGrath shared. “It’s got to come to a head somehow.”

Supergirl airs TONIGHT @ 8PM ET/PT on The CW.
