The pack is starting to sort itself out. The Smart Ones have figured out their only road back to a life of happily never paying your own bills is to take whatever they're force-fed here and choke it down. To that degree, they're going to at least give some effort in the various tasks, although they may dodge out of it whenever possible -- witness the issues visible in the initial housecleaning. For most, this is 'fake it until you make it': the lessons are unlikely to sink in and the whole experience will be treated as cramming for a course whose only purpose is a graduation requirement, where total forgetting of material takes place at the exact second of handing in the final -- but at least they'll try to give off the illusion of reform.
The Stupid Ones are exemplified by Gia. (She's hardly the only one -- just the worst.) The world exists to do their bidding, and this situation is a momentary aberration. They will continue to act as they always have because this experience has to end eventually -- and once it does, things will go back to their normal with no concessions on their part. To concede anything, much less change in any way, would mean descending to a level they only acknowledge the existence of at a great distance. So they'll wait. And then they'll go home. Followed by taking vengeance.
But those divisions are what existed before they were told what the goal of the program was. Now that they've all heard that they're actively working back towards their old lifestyles -- well, to continue down the Stupid path is going to require a sense of entitlement that, luckily enough, you'll already find in the house. In quantity. They should all realize they've at least got to fake it now -- but...
Other notes:
I don't like the VIP position. Maybe you do need a reward system with this group because it essentially comes down to training purse dogs, but they were clawing at each other before the perks appeared. Too many queens in the hive -- at some point, the stingers are going to come out.
As far as Voldy's appearance goes: you had to figure she lived like a pig. (Sure, production could have wrecked the house on purpose. I choose to believe otherwise. Voldy would understand: after all, believing otherwise is all she's ever done.)
It might have been better to tell the massage receivers about the celebrity endorsements after the experience. Say, at the end of the series.
Too much fighting, too many insults, and welcome to Total Drama Household: you won't be staying long. No one could stand to stay for very long. Well, maybe if they offered you Gia's rejected (and theoretical) cleaning million...
Gosh, what a fun shopping trip. I hope some of their furniture is edible, because that did not supply nine people for one week. Innocents abroad in a place with no grocery bagging. Which isn't a problem, because most of what they purchased didn't look like groceries.
Does anyone in the house have a T-Bird? I'd like to see their daddy take it away.
