Heh. It took me a minute to figure out what wife and son you're talking about--they've become such non-entities to me.
Yup, that sounds about right. After all, it's all Pandora's fault in the first place for not stopping Abbie before she ran off with the shard. And for goading Abbie into destroying it. Forget the fact that she went to an awful lot of trouble to bring that ungrateful, whiny bastard into this realm in the first place. I really hope Pandora's the one who gets to kill him.
If I remember right Hawley found them a Shoshone (?) cure but after Crane recited the spell/cure they didn't think it took but then Abbie's bond to Joe is what finally made him change back to human? Maybe?
