A desperate, lonely person, facing mortality, does what they can to see people she loves but isn't allowed to visit due to estrangement? That's "super weird" to you?
it does point to a pattern. Both me and the rest of my real family don't talk to our bio families anymore and this kind of stalking behavior is something I'd expect out of one of one of those boomer assholes! objectively its super weird though, and also not strictly legal.
