It's wrong that Angela has been able to talk to Garth, no fairness in the "game" at all. Maybe more entertaining, but makes a mockery of the concept of the game. So much for "who wins? You decide"...
You know I have just thought of the reason why they have all the camera runs with glass angled so they “project the pattern below the box onto the glass. It allows the producers and camera crew to be in there and NOT seen in any of the reflections. If you notice there are no reflective surfaces that could show someone aside from the bathroom mirrors.
Even though I like visually how they look better, it’s another tactic they could have used to hide the fact the producers were in the house with them.
