Question: Why did Terry and Erin put the kids in one bedroom at first? They had another room anyway, as is revealed when they suddenly make the new bedroom for Ruby, before the social worker visits. And if they want the kids to trust them, it would make sense to give a teenage girl her own room.
Question: When Ruby is talking to the woman from Child Services, she says "You're writing everything down, now everything will be written down twice". But when was the first time that stuff was written down?
Answer: The first time the information was written down was more than likely when Alvin Begleter (the trust attorney) initially contacted the Child Services rep, as it was through him that she found out about Ruby and Rhett's situation in the first place. At the time, the social worker would have written down what Mr. Begleter was telling her so that she could a) have something to refer to when she later visited Ruby and b) so that she could compare the two versions to make sure there were no discrepancies between the story she got from the attorney and the version from Ruby.
Question: Was Terry attracted to Ruby? There were a number of times when he acted weird, like staring at her when she got out the pool in her bikini, reaching over her to put her seatbelt on, etc. If he wanted her to trust him, why did he act like such a creep? Wouldn't it have just made her more suspicious?
Answer: My theory is that Terry deliberately acted like a creep to make Ruby uncomfortable around him. If she accused him of being inappropriate, he could deny it, making her look like the "troublemaker." She already has a history of being in trouble at school and sneaking to parties/raves. And he set her up for another accusation of plagiarism. He probably wanted to get rid of her because, unlike her brother, she was not fooled by him and Erin. He later points out that they only need one of the children in order to get the money.
Answer: Terry told them when they first moved in that it was only going to be temporary so that they would think that they would eventually get separate rooms, but I think they always intended to keep Ruby and Rhett together in the same room so that they could easily monitor their movements. The only reason they quickly knocked up a second room (for Ruby) for when the social worker came, was to carry on the charade of being responsible guardians for them, and they knew if the social worker saw that a teenage girl and her younger brother were sharing, it would raise red flags, and they needed everyone to believe that they were responsible enough guardians, so that they could keep the kids and eventually get their hands on the trust.
