Supergirl: “The Last Children of Krypton” Preview Trailer

Who was that lady at the end of tonight’s episode of Supergirl?

That was actress Brenda Strong and who knows, hopefully we’ll be learning more about her mysterious Cadmus-related character in the October 17 episode of Supergirl, which is titled “The Last Children of Krypton.”

Superman continues to guest star — yes, we do want him in his own show sometime — and you can find some official preview images underneath the trailer which aired on The CW tonight. Now updated with an extended version… and you can see some screen captures here.
