@Nobodyman:
Sasuke: Oh, hey guys, look at this. All the materials I need to resurrect Orochimaru have all been conveniently gathered in this indistinguishable place in the middle of nowhere.
Suigetsu: Oh, well…it must be a very arduous process that requires a shitload of chakra or a sacrfice or something, right?
Saskue: Nah, I can do it in, like, two seconds.
Sasuke sticks a thing in a thing and pulls Orochimaruo out of Anko's neck
Sasuke: Well, that was easy. How's it hangin' Oro?
Orochimaru: Oh, you know, suspended in perpetual limbo in the consciousness of my former student, while still being totally aware of the outside world around me, but unable to do anything.
Sasuke: Yeah? How was that?
Orochimaru: Actually, compared to having to be around you again, it was pretty damn enjoyable
you know how Itachi killed Orochimaru by having him jump out of Sasuke's neck and now Sasuke revived him by bring i ng him out of anko's neck. Does that mean that there could be as many orochimaru's as people that have that curse seal on them?
How many people are there with that? Can more than one orochimaru be revived at once? If 100 people had that seal and Sasuke went to them all, would there be 100 REAL orochimaru's? This kind of feels like harry potter with he who must not be named sending his soul into like different objects to gain immortality.
In that thinking, if someone revived Voldermort with those seals what happens if more than one is unsealed at a time? Would there be multiple voldermorts running around then?
