After finalizing the plan, Mary excused herself from Rei, Anton, and Roana in Anton's study to freshen up before going to bed. She opted not to participate in their discussions to minimize the chance of making mistakes by limiting her knowledge of the plan.
To maintain the deception, they collectively agreed to continue portraying Mary's dislike for Roana, ensuring that Kevin and the others would believe it. They also made an agreement to withhold the details of their plan from Amy and Henry, ensuring the effectiveness of their staging for everyone involved.
Enjoying a warm bath, Mary's thoughts wander whether Roana's interest in Anton had truly subsided. Yet, she made a conscious decision to allow time to unveil the truth rather than hastily jumping to conclusions.
