I do believe Lee's confession that she killed Mason, but someone had to help her. Remember when she was being interrogated by the police and she questioned the cop if he believed she could have hung up Mason alone? I also think the twist in the story will have something to do with Emily...the little child Lee had that disappeared, prior to Flora. Emily has only been mentioned once and I feel it is somehow part of the Mason murder, Lee, Flora, and everything else going on.
I agree with the PP that hates Hostel and all the 'torture porn' movies. They are terrible, awful, and horrible. But I don't think last episode crossed the line into that territory. If it had, I wouldn't have been able to stomach it.
Audrey is my favorite character, she cracks me up. And I would've killed Mama Polk just like she did. If someone tied me up, fed me pieces of someone else, and tried to kill me; you better believe I'd do them in if I could before they could come after me again.
