I watched it like two nights ago, very disturbing.
I find that Bear never really was in love with Nikki. I would call his attraction more of an infatuation. He cared only to fuel his own selfish ideals; he didn't truly care about her well-being (up until the end).
I loved the scene with the plant pot. It was so fucking creepy; she moved sporadically like a ghost.
I also loved the bit where he called customer service, and you could hear the real Nikki screaming. It sounded like she was in hell, yikes.
