Well would you look who it is? Only Ms Patricia Arquette herself. She is guest starring tonight in an episode of CSI as Agent Avery Ryan, and would you believe her character is based off an Irish cyber-psychologist called Mary Aiken who is also the inspiration for a spin-off series of the show called CSI:Cyber starting next year. How cool is that? This episode is pretty much the show's way of introducing this new series to us, as they bring in Avery tonight to assist in an investigation into the murder of a wife of a casino mogul. Kind of expecting Arquette to have psychic powers similar to her character in Medium.... but we're sure that's not the case, well, pretty sure.
