Hiya I'm a long time lurker but finally joined because I'm not sure if anyone has suggested this.

I know it's unlikely, but so are a lot of the other theories like her already being pregnant, an illness when no details whatsoever have been given etc.

So I'm guess that it is either a fix. That she is the new power housemate and for some reason it is being covered up completely. Or Steven's crazy controlling behaviour finally got too much, the psychologists were worried about her and removed her for respite.

Very weird though!
