Night Moves
After a burglary in the apartment building where John and Catherine live, he seizes the chance to play on her vulnerability; Dexter's mom and Cathy's beau have something in common. Catherine is very scared when a thief breaks into the building she lives in. John exaggerates the danger, figuring that if she's frightened she'll want him around. Meanwhile, Carly introduces everybody at the terminal to her millionaire boyfriend, Karl. To Dexter's dismay, his visiting mother recognizes Karl from when she worked as his nanny.
