My thoughts are the obvious, it's selfish, sad, dysfunctional, and/or not nice or very cruel depending on the details. It also kind of seems like there are a few people engaging with someone else's false identity knowingly, like an unspoken roleplay, like they're both in a shared escapism prison and are both gonna claim to be victims when it's all over. And I sort of wonder if they come out the other side of that bonded through the weirdness they created, or just fully hating each other.
