I know putting Kim in the attic rooms is to humiliate her, but... if Frank truly cared about the baby's welfare would he really want her having to go up and down those narrow stairs? She just came out of hospital and she's miscarried before, so... does this really make sense in the long run? I'm not sure I'd trust her not to cause a miscarriage. What of the nursery rooms Nick was staying in? Wouldn't that be better suited for her needs? All he'd need is one of those cameras placed outside the door to monitor her comings and goings.
