The Neighbor
- The next morning, Matthew knows that he has to go looking for Murdoch. Things are bad at home—Nikki is screaming and throwing things and the kids all have to barricade themselves in the bedroom.
- At some point, Rob comes over and, after listening in on his conversation with Nikki, the kids realize that their mom seduced Rob in order to sic him her ex-boyfriend.
- When he's supposed to be at school, Matthew goes on over to Murdoch's house and sees that the windows on his car are totally smashed.
- He walks over to Murdoch's neighbor, Julie, and asks her if she knows where Murdoch is. As he's talking to her, though, Murdoch comes out of Julie's house and Matthew realizes that Nikki has been replaced… which means that they've been replaced.
