Lacy Darer is a deceased Sim who used to reside in Twinbrook. She presumably passed away in the fire Juan Darer started, and is buried in Juan's Pick'n Pull junkyard. Because of that, it is thought that she may have been Juan's wife or ex-wife. She died before completing her lifetime wish. It is also speculated that the fire that destroyed Juan's home also killed Lacy's possible twin sister, Macy.
Many players have noticed she bears a resemblance to Macy Clay: they share their hairstyle, dress, face, favorites, traits and tattoo. Their personalities are nearly identical and they both died in a fire. Moreover, their names closely resemble one another. All of this might indicate that Macy and Lacy are twins. However, their family trees don't show any relatives, so this is unconfirmed. She may be the ex-wife of Juan Darer, but whether she is or not is up to the player's imagination.
Lacy Darer is a young adult with grey hair, so it is possible that she dyed it during her life. Like all deceased Sims in Twinbrook, she has a pale green skin, grey hair and bare feet.
