Sorry, late to the party. Took me a while to shower and spritz myself with Axe to wash off the BO .
First off, I fell in love with Gaby for perhaps the first time on Sunday. She was always a hottie, but that episode with her and Carlos... heck, I fell in love with him too.
Now on to the mystery of Dave. Just how much of a leap are they going to ask us to make? Are they going to ask us to believe that Mike was involved in the death of Dave's brother in prison, and in a completely separate accident the death of his wife and daughter? Too much coincidence for me.
We need to understand why Dave had a parole officer/psychologist. We know the wife and daughter died about 5 years ago. He might have been sad and angry, but wouldn't have gotten a psychologist that he had to check in with regularly unless he had done something bad. And away from Springfield (or whatever the name of the town where Wysteria Lane is) since the doctor had to travel to get to WL?
I agree that the next piece to the puzzle will come from Mrs. McClusky and her sister. I even wonder if maybe Dave grew up in the neighbourhood, and there is some childhood event adding to the pain.
I have no spoilers on any of this, so all just my speculation.
