O'Leary's Grandfather

O'Leary's Grandfather functions as an off-stage familial anchor whose compact, pragmatic aphorisms shape HUD Secretary Deborah O'Leary's political instincts. He supplies pithy counsel—summed up in the proverb 'Never argue with a drunk or a fool'—that informs her restraint, tactical calculation, and instinct for damage control. Though never on-screen, his voice operates as a durable moral compass within the administration's private calculations, and Leo invokes his counsel to reframe O'Leary's capitulation as strategic rather than merely personal.
