18. Robbie Gets In Bed With Alex (Paranormal Activity 4)
After Robbie stays with Alex and her family when Robbie's mother goes into hospital, he begins exhibiting peculiar behaviour almost immediately. Things get creepier when Alex's boyfriend Ben shows her footage of their Skype "conversation" the night before. Alex is asleep, and Robbie not only crawls into bed with Alex but also puts his hands on her. The fact that the Robbie character still hasn't been sufficiently explained only makes this all the more WTF: was he just seeking some maternal affection from a pleasant young woman, or did he have more creepy, sinister intent? Either way, weird...
