Tricia Helfer to Guest Star on Criminal Minds

The gorgeous actress who played Number 6 on the reimagined Battlestar Galactica when it aired between 2003 and 2009 has revealed that she will be playing "a bad character" in the 2 hour long seventh season finale, which will focus on a bank raid which ends up in a hostage situation featuring several of the main cast’s characters.

The finale will also see Paget Brewster exit the show, probably permanently this time, after she was dropped in June 2010, only to return for season 7.
