'Intervention': Donna Must Confront The Addict's User Mother Before The Intervention Can Begin (VIDEO)

For an "Intervention" (Mon, 10 p.m. EST on A&E) to be successful in the long-term, the family support structure has to be strong and on board with the system in place to help the addict stay sober. That meant that Donna needed to address Mom Lisa's problem before she could even begin to have an intervention for her addicted daughter, Dallas.

So while the family was awaiting the intervention, she asked Lisa how she intended to support her daughter as a positive example if she's used with her in the past. At this point, Lisa became defensive and even started lying about what she had and hadn't done with Dallas.

"It's time for you to get honest with yourself," Donna told her. "If she sees you drinking. If she sees you doing all the things that you do, why should she stay sober?" Donna's reality check that Dallas is prostituting herself to make money for her addiction made her Dad break into tears, but only pushed Mom out for a cigarette break.

However, Mom was in place and played her part in helping Dallas through the intervention, and Dallas agreed to go into treatment right away. Later, it was revealed that Lisa also went into treatment for her own addiction problems, which is a great outcome. Perhaps the women can now find a way to have a better relationship that supports sober futures for both of them.

"Intervention" chronicles new stories of struggling addicts each Monday night at 10 p.m. EST on A&E.
