I think there's a distinction here because Petigrew and Crouch Jr aren't major characters/ family to us or Jo. I, again, don't think Jo would mess with family like that - she shouldn't!
Another point that just occurred to me is that both Peter and Barty Jr were seen in a good light that only became black with their 'rebirth' into the story. I hope you're not suggesting Dumby was a bad man under the illusion of being good??!!
No. Of course you're not!

If this "they pretend to be dead but then come back for the sake of a plot twist" scenario HAS to be played again, it'll have to be RAB but that would be VERY lame I reckon. I don't think it'll be Dumby. Why should it??? What would that add to the story??
