I guess Violet did die after taking those pills ... Another revelation (at least for me) was that Larry wasn't a ghost like the others. I was starting to question his nature when he would just constantly pop in and out of the house.
I felt that Constance really owned this episode, thanks to Jessica Lange's fine performance as usual. She was indignant when the two detectives suspected her of Travis' murder when she felt like a victim after having lost Addie and now, Travis. Best line: "Those Koreans. They're so suspicious now, especially after Hiroshima
." Then she accidentally dropped the kitchen knife she used to threaten Larry in front of the cops.
God, I love that woman!
