VANDERVOORT: I was so excited, because I really had a good time shooting season seven, and everyone would ask me after then, “When are you going to return?” It started becoming a theme, where the answer would be the same: “I don’t know, they haven’t asked,” and then they called.
VOICES FROM KRYPTON: Stepping back to Smallville, did the experience feel different than it had back on season seven?
VANDERVOORT: It was a little strange, I hadn’t played her for almost two years. I had returned in season eight for an episode, but it was so brief, so it felt a little strange getting back into Kara. But once you get there, it’s not too difficult. I was excited and she’s almost a different character in season 10 than she was in seven or eight – she’s more mature, and she sort of figures out who she is. The tables have kind of turned, with her and Clark – in the past she would mess up and Clark would give her a lecture, and teach her about her powers, and when she returns the tables are reversed. She’s come back with more knowledge, and she’s teaching him things and giving him ideas about who he could be in the future. She definitely plays a huge role in his becoming Superman.
VOICES FROM KRYPTON: What kind of role does she play in helping him become Superman?
VANDERVOORT: She’s in the red and blue, semi-Supergirl uniform, without the S, but she does do the brunette wig and glasses, which teaches him that he can have an alternate identity. He can have a face to the red/blue blur, and still be able to walk among the people with another identity. She kind of gives him that idea. I saw the photo – so I guess it is public knowledge that she wears that – but the second part of the reason, the producers told me, about wearing that, was to give him the idea to do it, to have the courage to show his face as the red/blue blur.
