A few things
Who stares at a naked man swimming and gets all weirded out when he looks back at her. He looked at YOU because he felt you looking at HIM!!
The baby was in her crib asleep. So why did Rose get reamed? Was she supposed to stay in Taylor's room and watch her sleep?
I would ask someone what they meant by the girl should dress more appropriately and which girl. If he was bothered by her bathing suit, gasp, humans have skin!!
Why was Chloe scared of him finding her in his cottage? She owns it. She can say she was looking for the cat, since she was and she heard the meows from inside.
If they were so paranoid they should have called the police. Although it's his word against theirs and he could have taken the baby monitor out of the cottage by the time they came.
I can buy Rose leaving her laptop unlocked once, but twice? It was clearly to set up her sister and Chloe.
So the dude was a Polygomist with a fetish for Teen girls with low self-esteem?
Why did she leave the truck and not drive right to the police?
That was creepy.
