Ray feels that he was conned by Steph's display of self-pity into voting for Nush - or "sacrificing" her, as I think he described it. I agree. In his mind, Ray thought he was being kind by bending to Steph's distress, trying not to upset her more. Right motive, wrong decision, Ray.
Steph comes across as a self-serving little madam who plays the game as much as anyone. Notice that she's never thanked Ray for saving her @ss this time round, or even acknowledged it. She even complained of all the attention being on Nush after Nush had been nominated! What a moo!
In a way, I'm glad that Cameron wasn't up against Steph this week as she'd have been bound to go. At least with Nush, there's a (slim) chance that Cam might be voted out, and
then wouldn't the group dynamics be interesting?
I have no favourite. They all have their pros and cons - more cons than pros. But I'd like to see the painfully smug Cameron out this week as I think it would reveal more truth about the remaining HMs and perhaps point to a potential winner, someone I'd actually want to pick up the phone for. Not holding my breath, however.
