So if Jess is in prison but they left Quebec to return to her family, she'd have to have to have been deported with a reciprocal arrangement to serve her sentence in the UK.
Why would she rather be in a prison near her parents, with Rob in Ambridge, than in Canada, where Rob could have kept his lovely job? If indeed this is a choice that can be taken. Doesn't quite seem to add up, unless deportation was automatic.
So, if she did something criminal related to his scars, drunk driving?
I'm not sure about prison. I do wonder whether, rather than being obsessed with her job and tied to looking after her father, he is looking after her and she is in some sort of institution, perhaps a secure hospital? I still think Mrs Rochester is more likely than, yet another, more or less likely, more or less criminal (Clive, Susan, Roy, Tom, Matt, Susan's other brother).
He's drawn to Helen's sensible practicality and strength and may not know about her anorexia, Greg's suicide or Pat's depression after John died. So, one would hope, that if it turns our he's treating a mentally-ill wife terribly, Helen should be outraged, disgusted and repelled.
But where's the long-term opposites attract, mega / mini dairy familial tension and fun in that?
