Ok, so that scene of Hugh Grant at the hospital last episode WAS a flashback - seems like a cheat, making it seem like he was there at that time. Now I know this is the kind of show where I can't trust what they show us, which is annoying. They should have made that more clearly a flashback.
Yes, once the lawyer friend had taken his case, she's bound by privilege, but is she bound by privilege if he asks her to take his case and she says no? Why would she ever say yes to representing her best friend's husband without her best friend's knowledge, especially on a sexual misconduct charge? Isn't it part of her job to avoid such obvious conflicts of interest? I hope that is going somewhere - like the lawyer friend did the murder, or was having an affair with the husband - rather than just being a bizarre inexplicable choice by the lawyer friend (what's her name?).
Nicole Kidman going down to the police station all alone without a lawyer or purse or anything, on the spur of the moment at night, was ridiculous. At least she eventually summoned her knowledge of things like custodial situations but she should have started by saying she'd be happy to schedule a meeting with them and her lawyer the next morning. How did the police know to find her at her father's house?
The credits with a little girl and blood seem like maybe there was some murder buried in her childhood which she has repressed memories of, or something along those lines...
If she believes her husband probably just beat a woman to death, one he was sleeping with, then she should be afraid of him and trying to placate him and calling the police once his back is turned, not confronting him to his face all alone with no witnesses or protection. And she should probably have had some kind of protection at the beach house, given how rich her father is.
