Who came in last was no surprise to me either. At least they did not have to worry about others taking care of their busineess left at home for long.
Karen, I can't figure out who you mean by the whiny husband and his poor wife. Terence is whiny but he and Sarah are not married.
I like the brother and sister, Nick and Star. I also like the geeks and the mother and son team although I don't think the later will be able to make it to the end.
