Normally, one would expect a level of privacy. However, if all the participants agree to reveal what’s going on in the sessions, as I’m sure is the case with their contracts with VH1, I don’t think there’s any reason why they can’t have cameras in there.
It’s clear Danny’s melt-down is getting worse every week. From the previews of the upcoming episode, it looks like he’s going into rehab next week. I’m not sure if that’s when the filming stopped (that we’d heard about before the show went on the air), or if that was referring to last week’s episode when
Danny tried to commit suicide.
