In this situation, the best description for why Regina tells the group, "I explained to Ben that perhaps you hadn't answered his letter because you didn't think he was offering you enough, and that the time was getting short and you could guess he needed you—" is to convince Ben that he has been wise to trust what she has said.
1. Regina's statement implies that she is trying to manipulate Ben's perception of the situation by suggesting that the lack of response to his letter was due to his offer not being substantial enough. By doing so, she aims to make Ben believe that he has been correct in trusting her words and intentions.
2. This tactic is a form of manipulation designed to maintain Ben's trust in Regina and potentially influence his actions or decisions in the future based on the narrative she presents to him. By portraying herself as understanding Ben's needs and motivations, Regina seeks to solidify her position in his eyes.
In summary, Regina's statement is likely intended to convince Ben that he has made a wise choice in trusting her and that his interpretation of the situation aligns with her narrative, ultimately aiming to maintain and strengthen their relationship based on her version of events.
