Call it professional interest. You see, Jessamine, love is a kind of poison; one of my favorite kinds, in fact. It infects the blood; it takes over the mind; it seizes dominion over the body. It amuses me to think of him pining for you. Aching for what he cannot have. The loneliness in his soul is festering like a wound. There is nothing I could do for him that is worse that what you have already done, my lovely. And I assure you, in his case there will be no cure.
