Todd Allison & the Petunia Violet/WMG

Violet is some sort of spirit or mind control entity that takes over people's bodies
Eventually, something will happen that will cause the entity to posses/control Petunia, adding an extra serving of drama. (Note: By mind control entity I mean a personality that is written over someone's existing personality)

Todd will get a relapse of TB
He's never been a healthy person. And it's happened before.
