When you don't sit next to Aria and the couch and she just says she's going to sleep, the lines after it don't make sense. It seems to imply you slept with her when you didn't. A similar thing happens if you pick certain choices with Camilla when you are at her house, but you don't follow the sexual choices, but later in the car it looks like you had oral sex. So it seems like if you are trying to chose a set off choices where you are only targeting one woman, the dialog doesn't match up all the way.
