I mean, let's look at all the revelations we are currently
not inflicting on Hazou.
- - He doesn't really know his mother and he probably never will.
- - He's the kind of person who's fascinated by Orochimaru's horrors even as he's disgusted by them.
- - He's pretty OK with people dying so long as they aren't people he knows.
- - He's actually still the kind of person who thinks of others as "skinwastes".
- - He weaponizes things instinctively.
- - He's socially terrible in a lot of ways and doesn't know how to relate to others.
- - He'll never be able to have expressions just flow from his heart rather than be things he chooses to wear, like clothes.
- - He doesn't know what he's doing and he's not really in control.
- - He comes up with brilliant ideas but can never depend on them, they just kind of happen to him.
- - There is a part of him that considers no price too high for the world he desires.
- - He's simultaneously too old and too young, a creature that doesn't fit in society and can't really relate to anyone.
- - He talks a big game, but still has issues actually caring about people. He seems to treat everyone as cute pets, not people worth listening to.
- - Like Keiko, he uses intellectualism as a defense mechanism.
- - He wants to speak his heart but he's become a liar to do it.
- - He's scared shitless of a lot of the things he's done to himself.
- - He's seen the Out and it feels in some ways more natural to him than life in this world.
Etc, etc. I could go on.
Let me go through those:
1, 2, 5, 11 aren't things the clone should have a different perspective on compared to the original.
3 has a good chance to not be relevant to the first meeting
4, 10, 12, may be the types of hypocrisy visible from the outside
if it comes up in conversation.
6 is definitely something he'll notice.
7 will screw over the first clone
massively. But that won't be something the clone will use against us, it will be something that the clone will try to deal with while Hazō (who due to us will have planned for this eventuality) does his best to help.
8 might be noticed the first time a clone gets told to do something by the original. Especially if they happen to disagree due to, say, having a slightly different balance of plan votes. Or however that works.
9 May be
massive. Not to mention
interesting. But it heavily depends on how the QMs judge the hivemind to work in relation to Shadow Clones. If it is simply
gone like Frozen Skein or other Bloodlines and if, on top of that said lack is imminently noticeable as more than just being objectively less creative in a subjectively opaque way, then Hazō will literally believe to be possessed by an Out entity.
13 isn't something I noticed and I'm not sure I agree now that you've pointed it out.
14 I don't know if the clone will notice or what it might do about it. Hazō will definitely see through all kinds of bullshit. Similar to 4, 10 and 12 I guess?
15 Maybe clone Hazō will call meat Hazō a massive idiot, for catharsis. But this isn't something unknown to Hazō.
16 The Out is a massive question mark. As it always is. We can't really speculate as to how that whole shizzle will interact with the Shadow Clone jutsu. Neither can anyone else. Which is a good reason for our clan to not allow us to learn the ability in the first place. Also, see my answer to 9.
To recap: Hazō's first clone will literally be handicapped. He will be able to see through most of Hazō's deceptions and hypocrisies, but not necessarily through his self-deceptions if they don't visibly come up. This may get overshadowed by the massive question marks that are Out/Hivemind related stuff.
Also, that other Hazo? He'll be distracted by trying to quickly learn how to breathe and stand up straight while simultaneously remembering to clench his sphincter muscles. He'll be half-immobile, defenseless (emotionally as well- no poker face to hide behind) and probably at least a bit scared of dying (Prophet or not).
I don't think it will be quite as bad. Hazō is able to (terribly) play the flute without his bloodline. So the clone may be almost as skilled as a civilian child at physical tasks if we are lucky.
