Joe was shown to bond with Anita as primary user, and Toby as "one of the" secondary users. Other members of the family were not shown to be getting bonded. As the bonding is likely to be done in the first introduction, the non-stop progress of scenes doesn't leave any scope when the mother, elder daughter and younger daughter got bonded to Anita. That means the three were not authorized users of Anita, thus, Anita should not accept any commands from them, that she does. Something got amiss in between.
Why make Odi wear a sweater? He cannot find temperature uncomfortable. It is okay if Synths are to wear some clothes so that they wouldn't appear naked, but when it was having a shirt and pant, why add a costly sweater? A Synth doesn't need inner-wear also.
