 After the spec script was picked , series creator Chris Carter and the show 's staff reworked the ideas into a teleplay . Carter focused the plot on the themes of greed and vanity , and executive producer Howard Gordon created some of the most graphic moments , such as a phrase written in blood on Franklin 's bathroom . Vince Gilligan named Theresa Shannon after actress Shannon Tweed . After Carter had the idea of placing a subtle pentagram on the reunion table , production designer Graeme Murray decided to take this further by creating rooms with five sides , and having the plastic surgery unit with five operating rooms represent an imaginary pentagram . Like previous episode " Home " , Fox Standards and Practices objected to the graphical content , and Carter had to intervene to help retain some scenes .
