I have done my best not to give anything away that would spoil enjoyment but read with care.
There comes a point in the story where credulity is stretched to breaking point. In my view there is no way that Angela would behave in the way she does at the crucial point (in my view the dramatic needs of the scriptwriter(s) are not sufficient). Her stated reason (protecting Jane) holds as much water as a colander. Just ask yourself what you would have done in the circumstances. And then ask yourself how on earth there would be a way back for the affected party particularly affected by Angela's behaviour notwithstanding the final outcome.
