Will Delia clear up the mystery?
I'm not surprised that Denise is Denise and not Ava. I wonder if Delia had twins and they were both given up for adoption. That's really the only explanation that makes sense. I don't imagine that Delia had two children with Ava's father.
The emergence of Denise is a good thing. It brings back Maura West in what promises to be a very colorful role.
