Alicornutopia

Let's assume it's Vorkosigan-verse and thus advanced biological techniques exist and are probably mentioned in the notebooks. The clone either gets identical scars or gets a plausible explanation of how the healing treatment after their horrific accident would have also healed away scars (not entirely sure if Vorkosigan-verse is quite good enough to duplicate scars, so probably the latter?). As for mental tweaks, I mean like, slight differences in sensory processing, processing speed, or something on that level, which might propagate into their preferences but is not a change directly to their preferences. Let's say everyone the Bell knows is in on it - they are the subject of very top-secret level biomedical experimentation or something.

By valid I mean like - if they notice that their notebook says they should be one way, and they are in fact some other way, and they don't know of anything to account for that, do they go "my mind has been tampered with" or "my notebook has been tampered with" or just like, assume that their mind has since changed for unexplainable reasons and update their notebook accordingly, or what?

They can totally duplicate scars or Mark could never have passed.

Bells expect to change over time and wouldn't necessarily notice something up if they used to enjoy brussels sprouts and then stopped, or something. The quality of the security on their notebooks would affect how readily that possibility would come to mind.

Unless the healing treatment in question was "your brain was transplanted into a clone body", faking the scars would probably be easier than inventing something that could supposedly erase them...

...of course, "your brain was transplanted into a clone body" could in effect be the thing that happened, except instead of a brain transplant it's, heh, a notebook transplant XD

Cryorevival has the amnesia effect.

Yes, yes it does. And now I'm imagining somebody close enough to a(n irretrievably) dead Bell to know about the notebooks and unscrupulous enough to have the dead Bell cloned and then have the clone frozen and cryorevived - probably after never letting the clone gain consciousness on their own, because somebody this unscrupulous would have read the notebooks and would realize that any clone-life memories sneaking in would blow the whole scam near-immediately. XD I cannot fathom why this person would want to revive a dead Bell in this way, however.

I haven't gotten to the parts with Mark yet and have been actively avoiding info about him, so :P

But, yeah, part of what I was wondering about was to what extent a notebook-transplant would act as a mind-transplant, assuming the actual physical substrate is mostly similar. The other part I was wondering about was how Bells identify that they/their notebooks have been tampered with and how they react to that. (It sounds like that one is going to be heavily contextual even in the case where both things are possible.)

I have no idea why someone might do this to a Bell! I'm currently reading Ethan of Athos and there was a bit where they were talking about things you can get done on Jackson's Whole and something basically like that was one of them (clone the dead person, age them up, pass themselves off as their former selves with them none the wiser). And they were talking about 'reconstructing the mind' based on information about the person and how they could tweak it if there were things you wanted changed about the person, and I was thinking about how Bells have a lot of information about themselves in the form of notebooks, and wondering how that would work and if they would notice that someone had changed things about them (or even just if the cloning process hadn't been perfectly precise).

Reading old notebooks and reconstructing the thoughts behind them takes time. If the dead Bell did ciphering or had complicated access codes for the notebooks all bets are probably off. But yeah, heavily contextual. Closest case is probably the Cycle crowd but they have the dreams too.

(It is worth create a template in Miscellanea for this?)

While, I know that it is logistically impossible, but I am curious about what would result if we had "all" templates in a single highschool AU of sorts (which means they would either go or possible work in the same highschool in a very Earth-like setting excluding some due to parental relationship) and how the relationships would develop. Like, Aestrix said that Zevis would think that Jokers are "the best thing ever", but at same time Mathildas might be friends with the Joker for different reasons, and I am not sure how the two friendships would affect one another Zevis-Mathildas don't seem likely friends albeit they wouldn't really be enemies either...

There is also the matter of the Edward template, which is supposed to only show up when there is no love interest. For Science! I am sort of curious how things would shape up in a non-metacasual way... Would Edward be able to compete with Adarin, Sherlock and Joker?

Or how would the three Swan Siblings friendships shape up? Maybe Emma would be friends with Alex? and Soph with Jenny?

Soph/Jenny friendship sounds great, I'm less sure where an Alex would gravitate. I think if there's only one Bell in the school they'd be most likely to go for the Adarin over other possible love interests, although an Edward could make a fair showing and depending on initial setup / timing of Adarin shyness could 'win', and so potentially could some purples if they actually tried instead of being sort of - passively enthusiastic in the way that purples are often inclined. The Bell and Matilda would probably be best friends less whoever the Bell is actually dating.

If I put a lot of purple templates into the same high school AU, they would form a giant polycule and the local Bell and Adarin would be free to hook up. Unless the local Libby got to the Adarin first. In which case I guess Bella gets to default to Edward.

So much of this depends on who meets whom in what order, though. XD
