"Disclosure."

That stupid file was first mentioned almost two years ago, in "Housesit." And it may have only been a joke at the time, but after multiple episodes of people showing up to steal it (and S.H.I.E.L.D. running a sting to pick up criminals trying for it) I had an idea for what was in it. Namely, that having Kurt's name in it but scratched would be dramatic. Wolverine's name is in there as well, but I believe his corpse is encased in adamantium somewhere; even if you knew where it was, it might be problematic to get.

I'm pretty sure Peter David gave Multiple Man a pretty satisfying ending when X-Factor wrapped, so of course that was crapped all over in the recent crossover Death of X. Which I won't recommend, even if Cyclops is killed off. Still, Multiple Man has had dupes killed all over the place, there's probably more out there; but trying to keep track of his corpses would be a job.

But what would someone do with mutant (and superhero) corpses? And genetic material...there's a few answers, coming up later!
