Clive is complicit.

If Clive found out at the hospital that she was lying about having cancer, then he helped create Belle into a much bigger monster by enabling her. I was so disgusted by that party scene when she faked a seizure. I mean, we don't know if this happened in real life but this is so fucked up.

When my dad had leukemia, we also got so many alternative medicine tips. I remember my dad going home with a box of medicinal tea. This all brings back so much pain for some of us who went through it.
