I felt bad for Elizabeth when Matthew admitted that yes, there was a body, and yes, it was Bill Malloy. Even though it was obvious that something serious must have happened to dependable Bill, she had to have been hoping that it would all turn out well. At this point in the series, death is pretty final. And Liz was so happy when she said good morning to David!
When Elizabeth caught David eavesdropping, she said "You know better than to listen at doors!" Since when?
Elizabeth called Constable Carter by his first name, indicating familiarity, and now she calls the new sheriff by his first name, indicating familiarity. I'm having trouble keeping up.
Meanwhile Vicky's having trouble keeping up with David, even though he stays in the same place: fixated on dead people. If he's interested in dead people on rivers, she should have him read Tennyson's The Lady of Shalott.
