'Intervention': Kaylene Borrows Money From Her Kid Sister To Buy Prescription Drugs (VIDEO)

Kaylene was clearly delusional about what was going on, even as she was in the depths of her addiction to prescription medication on "Intervention" (Mon., 10 p.m. ET on A&E). When she was strapped for cash, the camera crew caught her asking her kid sister if she could borrow her money, lying and saying that it was for gas.

Even though her sister's entire life's saving was in pennies, Kaylene wanted it. "That's what I want," she told her sister. "Your pennies."

She promised to give them back, and maybe a part of her in that moment believed that she would. But anyone watching, or familiar with addiction, knows she would be far more likely to spend any future money on more drugs than repay her sister.

Despite that, she thought she was a great big sister. "I'm always gonna be there for her. I would have been blessed when I was her age to have a sister like me."

But her little sister, though she clearly loved Kaylene, was not so young and naive that she didn't see what was going on. "My sister is addicted to medicine and I'm not happy about it," she said.

Luckily, the intervention proved successful for Kaylene, who left for a nine-day stint in rehab and then returned to North Carolina where she started methadone treatment. According to the show, she's been clean since the intervention, which means maybe now she's finally being the big sister she always thought she was.
