This is kinda a stretch but I have some evidence for a prediction about Butcher and Sage

Is Sage gonna cure Butcher’s cancer? There are multiple references to Sage being smart enough to cure cancer like her story where she claims she could cure her grandma’s leukemia and Butcher seems fucked up beyond repair with a brain tumor. Butcher should obviously die in season 5 (in my mind he already has) but If the writers are really going for a happy ending or a sage redemption arc Sage could theoretically fix Butcher.
