The scene where Lynda is with her boyfriend in the van after they pull-up to the house.
"Annie will distract Lindsey., that's when we go up to the first bedroom on the left, got it?"
"First I rip your clothes off..."
"Not my blouse, it's expensive, idiot...!"
"Then you rip my clothes off, then we rip Lindsey's clothes off, I think i got it..."
Ummm...isn't Lindsey the little girl Annie is supposed to be babysitting? The actors turned the names around and it apparently wasn't caught or too expensive to fix...leading to a kind of twisted scenario.
