Where did this stuff about isolating her to such a degree come from? Did I just miss it earlier in the thread? Also wasn't she being employed in some capacity to work for his business as a streamer? She didn't have internet access and a computer at that point?
The isolation bit, if true to the extent you said, does explain the weird messages earlier in the thread where Ralph was communicating with her parents seemingly for her. I thought it was just petty teenage drama which Ralph was mediatingāit was really strange though, and it makes more sense if he was the only way to contact her family in California. The more this situation unfolds, the more psychopathic Ralph looks. Any one of these things (grooming a teenager across state lines, impregnating a teenager, bringing a teenager in a clandestine tryst across the country in the middle of the night, preventing a teenager from communicating with her family or the outside world, not providing for a teenager's basic clothing and health needs, assaulting a teenager, heavily pressuring a teenager into a threesome with two authority "adult" figures, and so on) he has done is bad, but putting it all together turns into Onision-tier cult behaviour.
Maybe Ralph does deserve to be arrested.
