Savannah Chrisley's complicated relationship with her brother Chase has gotten even worse... On the newest episode of The Chrisleys: Back To Reality on Tuesday, the 28-year-old daughter of Julie and Todd Chrisley expressed how scared she is of her brother's mental and physical health. She said in a confessional: "As hard as I am [on him], there is some fear in me that something's going to happen to Chase and it's very valid. I mean, just in the way that he looks. Chase is not Chase. It's literally, like, a blank shell. You can tell it in all the weight that he's lost.
