OMG they showed her going to the bathroom?? And being HBO they can show everything, not just imply what was going on.
Off topic, but, is there any reason to show bathroom functions??? We hear about gratitious sex in movies, but sometimes it is actually germane to the plot. I have a hard time thinking of any situatikn where characters doing their business is important to the storyline.
I need eye bleach.
There was no relevance that I remember - just to add "grunge" and "reality" I suppose. My conclusion is that she is mentally disturbed.
