Calvin was calm cool and collected as he approached the diseased spirits.  He would call out in a clear voice towards the stand as he stood where he was "If corpses are what you truely desire then why not take your spirits and yourself away from this place to one where millions live?"  He would ask as he stood there waiting "I know of a place where millions upon millions of corpses thrive, a place where a disease spirit like you and your dogs would have a really good time."  He would call out and wait to see if the spirit would listen to him or rather stay and be stubborn.
