I don't think Dizi is in love with Ivory, I think she lust after him when she is drunk. Both times she was with him she was drunk, when she is sober she pushes him away. I think she only does what she does to stay in VV. I only hope she has learned by Tanya's experience with Tver to stay clear of the porn stars. They don't care about her only what's between her legs.
Petra is the brains behind Tver and all she is concerned about is money. I never understood why Tanya and Dizi would ever listen to her. The only thing I cam think of is maybe they look at her as a motherly image.
She was looking at the contract with Phil yesterday, it look to me like she was looking for something in the contract. She later was on the phone talking to someone about the contract. I really don't think she is happy in VV however it puts a roof over her head. I have a feeling she isn't going to around long.
These are just my opinions.
