I don't think the writers intended this, but the one mystery on Desperate Housewives that is consuming my thoughts while watching the show is the ever decreasing size of Lynette's family. Now, in the pilot she stated that she had been pregnant three times in four years. I thought that was odd since her eldest looked older than four. But, soon after we were told that the twins were 6. Then her youngest son mysteriously disappeared two weeks ago. Now, her infant daughter is MIA.
Oh, and Zach? That kid is terrifying the hell out of me.
