Background information[]

Alfonse Pacelli was played by a background actor with the surname Arratia, who received no credit for his appearances, but was identified by the fifth season call sheets.

An okudagram readout of Pacelli's personnel file was displayed on a viewscreen that Deanna Troi was studying. Some of the facts could be called into question since she was involved in a very detailed hallucination when the data was shown. In said personnel file, it was originally reported that he was born on stardate 40001.9. This was changed in the remastered episode to show stardate 20001.9.
