I'm writing an isekai story where a girl pops into a video game, but she sort of takes over the body and mind of a very conveniently-placed pre-existing person in that world. They have similar if not identical personalities (like I said, very convenient) but different memories and experiences. Over time, these two different "perspectives," if you will, sort of meld and grow together seamlessly. Right at the start though, IRL!Tiffany sort of "takes over" since she understands whats going on so much better and has a framework to understand and contain Game!Tiffany's perspective. I also have at least one occurrence of IRL!Tiffany having a panic attack about having to do something that Game!Tiffany is very familiar with, so Game!Tiffany takes over and sort of conveniently pushes aside all of IRL! Tiffany's memories to take charge.
And I realized it reads as plural just slightly, like different alters fronting, so I was wondering if you have any thoughts or advice on how to portray that as NOT plural, or how to lean into it if that might work? or if you might have any advice on how the whole growing/melding together might work? Is that a thing systems do or am I way off-track here? Also her twin sister is going through the same thing but I'm not writing from her PoV quite yet.
Additionally, the IRL!Tiffany is seventeen and the Game!Tiffany is twenty-four, so IRL!Tiffany is sort of going to rapidly age up during the melding process (which will take a few months to a year, so she's just going to slowly get more and mature as the story progresses, which works because I'm writing it while growing up myself and this explains why the quality and maturity goes up too).
But it also means that while IRL!Tiffany is sort of the main perspective for the story currently (i.e. isekai'd girl with in-universe memories to help her blend in / make decisions / roleplay essentially), Game!Tiffany has way more experiences/memories, plus it's her world they're living in, so the end result is going to look a lot more like "Game!Tiffany with extra memories from this other world that happen to include some knowledge of the future" since she has seven years more of memories. Although ultimately it likely won't matter at all.
Anyway yeah any thoughts welcome! It's not exactly plural, but I wrote Game!Tiffany taking over yesterday and realized you might have some insights.
I wouldn't know how you could write this as not plural because it sounds inherently plural to me. In some ways, it's a little like soulbonding, which is when someone from another universe joins your system
Looking at this from a plural perspective, however, the issue is with the melding. The reason that's an issue is because in a lot of plural stories, the plurality is seen as a problem which is fixed in the end by merging and becoming a singlet. Ending with final fusion isn't always bad, because some systems do want to achieve final fusion and would benefit from it, but those kinds of stories often ignore the option of healthy multiplicity and its benefits
So, my question is, do you need your characters to meld together, or could they happily remain plural? If it is necessary, maybe lean into the fact that melding means they'll lose each other and no longer be able to switch out and such. Even if they might be looking forward to having each other's memories and skills and being a singular person, there would still be some amount of grief there
Final fusion is also usually not something that happens naturally, but rather through a lot of work. Although, depending on how the system formed it could maybe be possible, and in that case you could lean into how maybe they don't want to meld together and lose their individual personhoods, that it's out of their control
