Good catch. I like Jack and Dave, but Dave is what make the feeds entertaining. Who else in the house would talk to the cameras?
I'm sorry I can't volunteer to monitor the feeds. I'm moving to Nashville this weekend.
Best of luck with the move. I should also point out that apparently the infamous "Expect the Unexpected" message (the one that showed up right before last years big twist which led to Amy returning to the game) showed up on the plasma screen in the living room, but none of the houseguests noticed it.
There is a lot of speculation that an ex of a remaining houseguest (Jack, Nathan, or Dana) might be joining the game, or that this coming week will not be an eviction week to make up for Scott's unexpected exit a few weeks ago.
