The (existent? non-existent?) entity behind most of Slugfest's intense philosophical discussion. Her famous September 2005 treatise, "On the Mystery of Me", has sparked many as yet unsolved questions. Who is she? Where does she live? It was once believed she inhabited the walls of Walcott 404, but it is now well known that it is actually Emily King who lives there. And all know that Emily King has no roommate. Further research is clearly needed, and UROP positions may be available to interested Slugs.
It is also interesting to note that her room number, W404, happens to be the same as the well known "File Not Found" error of the same name.
