I don't see Helen as unwilling Merlotgran but unable. She has been thinking in a way that seemed to protect her and Henry and she has believed much of the picture of herself that Rob has painted for her. I hope too that what Tom has said may trigger some memories and then she can talk but I also hope we hear she is getting some psychiatric help.
I am glad Helen isn't real - luckily the actor can walk away but the real Helen's live with this sort of thing for the rest of their lives and the triggers to feeling fear will now remain close to the surface for the rest of "Helen's" life - a form of PTSD. No doubt there will come a time when other characters will say they think she should have got over it, and even blame her for the way Rob treated her (victim blaming is a hobby in this country
) or that he was just a bit old fashioned, but I hope the SWs just have in the back of their minds that this will never go away - it will continue to effect her, Henry and the baby; let's hope for some good as well as otherwise but it would, if she was real, have a continued effect.
Now about Miranda ...
... and thank heavens for the lighter story lines
