Perhaps JB shouldn't have have given a dead man speaking lines. In my book that is over and above "normal". Had he treated him as a normal dead parent we wouldn't be having this conversation.
So him being recruited as a ghost the same as say, Carmichael or Papa Murphy was, means that he had to be magical in life???
And we had at least two good people who weren't special, Butters and Murphy. JB evidently hated it so much he turned Butters into a KOTC.
IMO That had less to do with him hating 'Normals' and more to do with him loving Butters a little too much.
I shudder for Murphy. Good people(especially women) end up dead in Harry's world.
I mean the real problem as far as Murphy's mortality is probably the fact that she's just gotten into a relationship with Harry, which... historically has not gone well.
Elaine: Mindraped into servitude by her Adopted Father.
Susan: Infected by the Red Court and then used as a living Sacrifice.
Luccio: Entire relationship was a lie caused by severe mental manipulation.
So far we're 0/3 on Harry having a healthy romantic relationship, and I doubt that's gonna change, it's too good a source of Drama for Jim to let drop with that many books left.
