It was "too soon" for Amy to have "figured out" her bank account had been drained by her "friend" KC? KC rips Amy off over a period of 3-4 days, right up until the hours prior to picking Amy up at the airport. Amy never knew all that time what KC had done to her, and your opinion is that it is suspect to you that Amy noticed as "quick" as she did?
Amy's what, 22 or 23 years old? That's the average age of the young people I work with, and if you told me more than 2 of them had $1400 balances in their bank accounts for more than a week, I'd be very surprised. KC depleted all of Amy's money to the point KC couldn't pay her $500+ cell phone bill. So we know Amy's balance fell below $500. Did it occur to you that perhaps the way Amy had to "figure out"she was financially raped by KC was perhaps Amy was denied a charge to her debit card when she returned home?
What leap are you making here to try to say that Amy would lie to LE about allowing KC to "use" her checkbook? Also, how could anyone owe KC anything? She didn't have a j-o-b. Anything she gave to anyone came from Cindy's credit. Yeah, they didn't know that - but how does that make anyone who wasted their time with KC suspect of anything?
Amy, TonE, Ricardo - they had apartments, cars, schools, jobs, close family, LIVES. KC was a wannabe, a poser, a leech, a parasite, a liar, thief, and a murderer. None of her friends made KC do anything she did to them. She made a career out of destroying people all on her own.
