I don't think Mrs. Hubber knew about any killing-I think she was too smart to blackmail over something that serious. I ran the tape back and this is what they said after Paul showed her the note that was given to Mary Alice.
Paul "Don't you feel any remorse, whatsoever?"
Mrs. Hubber, "Why should I? You're wife didn't kill herself because I wrote a note, she killed herself because of what she did to that poor baby. I'm praying for Mary Alice-after what she did, she'll need all of our prayers."
Then he whacked her in the head.
Later, when Zach escaped the hospital and went to Julies house, he said after his mother died , he remembered a few things, like when he was 4 yrs. old and he was upstairs, he heard someone screaming Dana and his name (Zach) he went downstairs and his parents were wiping up blood, but he didn't see Dana. He told Julie that he killed his baby sister Dana, didn't remember it, and that his parents would never talk about it. He said his mom took him upstairs and told him it wasn't his fault.
Was there a baby sister named Dana? Was Zach really Dana, as Hubbers sister said, "Will Marcia and John ever get back together" For the answers to these and other questions, tune in next week to " As The Stomach Turns"
Sorry, couldn't resist!!
