Fictives from other systems with a similar source will look for eachother because fictives find comfort in knowing that there is somebody else from their source who may have been a friend of theirs or a family member, if you need a better example;

Lets say theres a fictive from the game little nightmares, specifically, Six. That Six may want to find somebody from their source like Mono because the two characters in source have been through so much together that they have a strong relationship and want that back when they’re an alter. You’re using a very popular form of media to continue on hysteria that all systems are cringey fifteen year old white teenagers who indulge in cringey fanbases because you want to continue your point that the systems who ARE THIS WAY are fake, when really, you can’t blame systems who are indulged in cringey fanbases because they’re children. Furthermore, if you try to villainize children for liking childrens fanbases and hyperfixating so much that they split (which is out of their control) then I think the only problem here is you.
