A couple of things I didn't quite get
1. When Alex and Frank are loading the kids into the car to escape the cops, who's the old guy on the street watching them? The kids are gagged, struggling and trying to get away, so it doesn't seem like he just didn't see anything weird going on.
2. The scene in the judge's house - were the three girls upstairs his daughters? I'm assuming the one in the ballet outfit was. She looked quite a lot like Leslie (guessing not a coincidence) and was wearing the same outfit...are we to infer that he was using Leslie so that he might be able to control his urges to do those things to his daughter? Or was it just a coincidence that the girls looked alike? And what was the significance of the look that girl was giving Leslie? She almost appeared to be jealous, like she sensed Leslie was her "replacement" somehow.
3. this is a behind the scenes question: I know Ryan Simpkins was given an alternate version of the script so she wouldn't have to deal with the more adult subject matter, and a lot of the more difficult scenes were explained away, but did the directed ever say how they set her up for the "red light bulb" scene? When she's sobbing on the bed, what does she think has just happened?
