I guess I didn't really feel like Emily was all that sympathetic towards Sophia. I mean, in the previous episode she was bitching about the police wanting to talk to them instead of understanding that they were trying to investigate a girl's suicide. Not very sympathetic.

In the second episode there's this scene where she's crying over the flowers that have been left for Sophia, but that comes right after she found the picture of Naomi and Sophia in the prospectus so it seemed like she was crying over that instead of her death. And then she proceeds to lie to Sophia's mother so she can poke around in Sophia's things and steal stuff from her! I'm sorry, but just because she's decided to play detective that doesn't make it okay. It's not her place to rifle through Sophia's life like that.

I didn't think Naomi was cold, I thought she was scared and desperately trying to stop Emily from finding out. It doesn't mean she wasn't affected by Sophia's death.
