Lafayette is listening to Alcide Herveaux about having enough with supernatural bullshit, and that second to last one is no maenads referencing to Maryann's influence over Bon Temps. ("Turn! Turn! Turn!") Maryann also makes a brief Season 5 appearance, when Sookie after learning she may lose her fairy powers being half human, she remembers Maryann asking 'What are you?' and everyone else who asked the same thing. ("In the Beginning")
