Goof: Sister Vivian says that Sister Grace was pregnant at age 18. However, according to the tombstones, Grace was born in 1936 and Arnold in 1952, which would have made Grace 16 when Arnold was born.
Sister Vivian: (picking up Arnold's dead body) Clean the room.
Sister Grace: Where are you going? I want to come.
Sister Vivian: GRACE! This is not one of your little screw-ups! This is very serious.
The Boy in the Box
This episode has many very close similarities to the real-life "The Boy in the Box" case. In 1957, an anonymous boy was found in a box, wrapped in a blanket in Fox Chase, Philadelphia. Many of the items and contents of this episode bear striking resemblance to the posters made to help try to identify this boy, including propping the slain child up in clothes. The real case remains unsolved to this day, although the town he was found near raised the money to give him a proper burial.
