At best they have exchanged a few strained messages. Cayce is too obviously Parkaboy's friend, on the site, and Parkaboy's loathing for Mama Anarchia has been far too vocal, from his scathing assaults on the French philosophers she quotes to deliberately absurd personal attacks (considering he's never met her, and has no idea of what she might look like). This e-mail to Ivy is a fishing expedition of some kind, and a clumsy one. Although Mama Anarchia has no way, that Cayce knows of, to know that she and Ivy are friends, and discuss the site and its more prominent participants in private, and fairly frequently.
