I think the girl on the couch didn't say a word because it was based on JDs memory/idea of the ideal woman, whom he's never spoken to.
Did backpack guy shoot his real wife?
This season is shaping up better than the first, and the six episodes make it tight with no real room for filler.
The only complaint I have with this show (and most SyFy shows) is that their HD cameras seem to be about 10+ years old. There are dark scenes where the quality is so bad and pixelated it looks like someone upconverted a standard definition signal. It's distracting.
