^ Thanks for explaining everything!
About the "sociopatic" thing, I think that for so long she wasn't able to enjoy normal life because she was super famous and couldn't even go out like a normal person that she kinda became someone that enjoys being alone or surrounded by person she already know and trust and in her house. Maybe she can't chane that mindset. The weirdest thing for me is that her yoga coach lives at the house?? Or you mean the same building as her? lol
I felt the same way as you about them being careful with her. During the impersonators act it really seemed like they were affraid that she would not like it.
