I thought she had a real cat too and then when they showed her talking to it today, I looked at it and said to myself, "WTH???? It's a fake cat????" Bizarr-o.
They way she sort of freaked when she saw Paul, Nikki and the Father Corbin (:LOL) character, made me realize that she is/was Patti. That and the fact that Paul has been intrigued by her lately.
