they would both definitely not because juno is so over ghostly bullshit (one of his cases involved the occult and honestly he's Really Not About It).

but i think that sounds awesome :> maybe a fetch quest-type errand for a ghost who's lost an heirloom weapon of some kind on the battle field - and while they're on their way they find a nasty soul who wants some straight up vengeance because ghosts are inconvenient like that...............?
