I was waiting for the part of the documentary where the journalist switched the mother's medicine with equivalently sized capsules containing only sucrose and fructose. Of course the mother doesn't know that they have been switched, so she thinks she still giving homeopathic remedies to her child and herself.
The journalist checks in a few later and notices that the child isn't home. Upon further inquiry, the mother reveals that her son had in fact died in the intervening times between visits. The journalist begins to consoles the mother in a her best attempt to conceal her own guilt. However, before any condolences can be uttered, the mother continues to say that her son had died in a car accident.
¯\_(ツ)_/¯
