Dana Walsh: Affected by Shady Past on 24

When 24 returns in January, Annie Wershing says her character of Renee Walker will be "pretty damaged."

As for Katee Sackhoff's Dana Walsh, who debuts on the show's upcoming eighth season? The actress spoke on this character to E! News.

"I play Dana Walsh, the head data analyst for CTU, and she's engaged to Cole Ortiz (Freddie Prinze Jr.). She's got a shady little past, and we'll see how that affects her," the actress said, adding:

"It's the same usual 24. They're used to having new characters coming in. There's so many new castmembers this year that if it is the last year, they'll go out with a bang."

If it's the last year, let's also hope Jack Bauer dies at the conclusion of the season. It's the only proper way to end 24.
