Conrad orchestrates a plan to get Daniel involved in the divorce proceedings, Victoria plans to take control of Grayson Global and Jack begins to feel he's let his guard down with 'Amanda'. At the conclusion of the episode, Emily infiltrates Mason's home while he is at dinner with Nolan and manages to steal several tapes – containing interviews Mason had with David Clarke – before setting the house on fire. The next morning, Emily watches one of the tapes and learns the possibilty of Charlotte being David Clarke's biological daughter, and her own half-sister.
