okay so as we know, benny was brought back from the dead from purgatory and yes some beings have the power to probably resurrect monsters but lets face it, every monster in purgatory probably now knows of that method:

so we know-

one episode appearing monsters, and reccurring like lenore, gordon, Alpha Shapeshifter, Ellie

but the question is can Eve, Dick and the other dead leviathans come back from the dead?

first off, if a leviathan was killed by a human with a righteous bone, could they be sent to purgatory like dean or is it just the head leviathan that works on?

second off, could they be ressurrected? Eve presumably still has a body in Crowleys lab, dicks body and the other permanent dead leviathans(not neutralized like chet and edgar), could they come back from the dead without a body?
