Lie To Me - Funhouse

This was the second in a two-episode run and was the better episode of the two.  Emily has a friend that needs her Dad's help.  He is being held in a mental hospital and she believes he is getting treatment he doesn't need.  Cal is happy to help and goes to see the father.  Is the doctor just over-medicating to milk money out of the father's sister?  Cal sends his team to meet the daughter at the sister's house (her Aunt), the Aunt says she is not there, but they know she is.  Cal goes instead and while there tries a freshly baked muffin.  "That night, Cal goes back to the hospital and assaults an orderly and is then locked up and sedated.  Cal starts to see his dead parents.  Has he lost his mind?  Who is doing this to him and why?  A good episode giving some great background to the character of Cal Lightman.
