When editing in SimPE, his zodiac sign is not recognized. Also while William is recognized by the game as an adult, he has the appearance of an elder. Strangely when viewing his SimDNA in SimPE, William has grey hair genetics. This is unusual since grey hair is normally not reflected in SimDNA. He has no true hair genetics. According to William's age data in SimPE, he had 29 days left in the adult life stage when he died. His facial structure is seemingly exact to the 2nd Maxis face template in Create a Sim. Oddly, William is named "Martin" in his character file. It is likely that he was originally meant to be named Martin, but was later renamed to William.
