which one? because the quest to return your own soul to you suggest you do need your own soul back, and no one else will do. The same is true for a special value of Opening A Bundle Of Oddities - it is your own soul which is delivered to you, not some random replacement[/quote]
That could be just something to do with your infernal contract (you want that to end too, and it won’t end if your soul is still in possesion of somebody else?). Or the nature of the deal you get for getting your soul back through that storyline ("Go on then. Mrs Plenty says if yer finds it, yer welcome to it." - lightly implying that you are not welcome to grab just any soul, only the one that formerly belonged to you).
Coats are also interchangeable, but I would rather have mine than somebody else’s, if I can tell.
