The neighbor couple: loose end?
We early on are made to suspect that there is something suspicious about the couple living next door, especially the husband. When David brings the apple pie over, the wife breaks down and talks about how her husband is 'struggling' and that he is making things so 'hard and painful' . She then refuses to elaborate. What was that all about? It would seem that scene would have some sort of purpose or meaning? Or was it just put there to distract and mislead us from the upcoming twist?
Would like to be filled in if anyone caught up on anything I happened to miss.
