Mr. Lush is Henleigh Grandcourt’s longtime confidant and personal advisor. Shrewd and self-serving, Lush acts as a facilitator for Grandcourt’s schemes, particularly in his pursuit of Gwendolen Harleth. While Lush helps to smooth over complications, such as managing Lydia Glasher’s demands, his position is one of reluctant loyalty. He openly disapproves of Grandcourt’s intention to marry Gwendolen, fearing that her strong-willed nature will upset the balance of Grandcourt’s control. Despite his efforts to dissuade Grandcourt, he continues to carry out his employer’s wishes, ensuring that Grandcourt’s manipulations remain effective.
