Today comes the report that next season, Clark will not be the only survivor of Krypton to make it to Earth. 

While no one has been cast yet, The CW announced today that the show’s seventh season will begin with the arrival of Kara, Jor-el’s cousin. 

From the article at Zap2It:

“One of the joys of creating ‘Smallville’ has been our ability to reinvent and reinterpret classic DC Comics characters,” says executive producer Al Gough. “Miles and I believe that Supergirl will give our series the mythic jolt that it needs as we head into our seventh season.”

She will show up with an early start versus her cousin…she already has the ability to fly.
