Patsy and Cancer Returning

We heard John say for the first time that he made the decision to stop treating Patsy’s condition.

Anyone see this as a huge red flag???

First bc he could make a decision like that and lie to her about it. But also he said the cancer was starting to affect her brain. Perhaps metastasizing to her brain?

Was he worried that if her cognition began to go downhill she might reveal things that they had spent decades trying to cover up??
