It sounds to me like Shelley was questioning someone who likely isn't very serious about their treatment. I didn't watch the show so I don't know. But addicts need to be confronted about their garbage a lot. A lot of addicts have learned to be extremely good manipulators doing what they have to to pass and saying the right stuff. I'd be surprised if all these guys were not very treatment savvy and know what to say and when to say it. It takes someone like Shelley to jar them out of that pattern and maybe get through.
