I am still thinking that Helen will be found guilty of the lower charge. They will have (I think, does anyone know?) to take into account the time she has already been in prison on remand and, if they have got the message about Rob's behaviour towards her, have to balance that too - although not too sure about that.
As she will have no were else to go, she will live with Pat and Tony when she gets out so it seems reasonable that the family court look at Henry going to Pat an Tony as well. It isn't, after all, just between Pat & Tony, Rob or Helen. As I understand it they could all be found unsafe and he could be fostered.
Alternatively, even if Helen gets off both charges, she will still be living at the farm and I have no doubt Rob will have brought up the Otto incident to show it is unsafe whether Helen is there or not.
