Now he has the opportunity to talk to her in his new role as prison psychiatrist. Carrie is up for parole and he's going to be responsible for reccomending it or not. Her presentation changes every time they meet and Ethan isn't sure who the real Carrie is underneath the masks she wears. What is she hiding from and why is she so reluctant to talk about what happened to those children? Is it the shame of someone guilty of a horrific crime, or is she protecting someone else? Carrie is known to lie as easily as she breathes, but what if the truth is hidden inside those lies? Can you work out who is telling the truth?
