Suzie it's an interesting dilemma - "reporting" or intervening.
I will never forget years ago a young war reporter/photographer took an "award winning" photo in the Sudan of a starving child on her knees, surrounded by vultures sitting patiently waiting. That photographer later committed suicide, having been heavily criticised for recording the scene and not intervening (and probably because of having seen one horror too many).
I shan't be watching the programme, too depressing. It is extremely common for women addicts (especially injecting drug users) to be under the control of their partner.
