Anna waved her hands frantically when she heard that question from Alfonso, "No, no, no. Aaron and I did think about that, but we didn't go along with it." It was her who suggested to Aaron that they should go and investigate the Ricci family, but her brother didn't approve of the plan so they didn't make their move.
