I don't understand the rules of the body/soul swap and where Diavolo was hiding during the soul swapping shenaniegans of Silver Chariot Requiem.
Was Diavolo apparently hiding inside King Crimson who was attached as a summonable stand of Trish (along with Spice Girl)? If so this raises many other questions for me of such as
Why is it that King Crimson attached to Trish? Could King Crimson have happened have been attached to Trish, but could've been attached to anyone else as well? I would have assumed the stand to have been attached to the mind/soul as has been the case for the other swaps.
Why is Diavolo's "soul" inside King Crimson , a stand rather than a regular physical body like the other swaps (albeit Polnaroff is in a turtle transport macguffin that has stand...?)
Why didn't other souls get put into stands e.g. Giorno is inside Foo Fighters the airplane stand? My memory is foggy but I feel the question could be asked about how chaotic you want to make your swaps, does every bullet in Sex Pistols count of a potential body then?
Or is it the case that split personality thing made it so Trish and Diavolo mind/soul was in the Mista physical body she was inhabiting, and that King Crimson just has an innate perk of letting Diavolo inhabit it?
