Kathryn's attempt to sabotage Cherie backfires, when Kathryn's mother tells her to befriend her, to encourage Cherie's mother to donate a large amount of money to the school. In the end, Sebastian stays with Danielle; professes his love for her, only to discover she does not reciprocate. In fact Danielle is alongside Kathryn in a secret plan to dupe Sebastian. Defeated, Sebastian states "if you can't beat them, join them", leading to a threesome with Danielle and Kathryn, followed by an alliance of the three to dominate and manipulate others. Danielle gave Sebastian a journal to write down everything. In the last scene, Cherie is seen riding her bike, which is run over by Sebastian's car. He offers to give her a ride, having sex with her. Kathryn and Danielle are seen, in the front of the car, pleased with the results.
