[Well, that's interesting. If whatever pathogen or abnormal growth this is were only centered at her brain, it'd be unlikely that it could cross over into the rest of her body from there. Maybe it started off in both the intracranial cavity and in the lungs. That would be one heck of an onslaught.]
