Marshall first appeared in Orientations Part IV, Page 21[3], entering the Springfield Avalon and giving information about demons to Michelle and her friends. He mentioned seeing demons down in Arkansas prior to his appearance in the Avalon, but it is unclear whether those demons were the same demons that terrorized Michelle. Marshall and Eustace teased about Michelle being a sphinx, suggesting that if she were one they could make a lot of money by opening a show down in Branson, Missouri with her as the star, but it was unclear if Marshall was actually aware at that time that Michelle actually was a sphinx.
