Kate's assistant Leonardo (Baron Vaughn) is resourceful, unflappable, and, thanks to his vast and varied connections-and seeming uncanny ability to anticipate Kate's needs-invaluable. Dedicated to his harried boss and supportive of her at-times-unconventional methods, Leo believes in his work and is proud to help Kate make the world a better place. But though often called upon to help diffuse sticky situations, neither law nor mediation is Leo's passion: beneath his sweater vest beats the heart of a brilliant graphic novelist.
