 DATE: The guys all refer to Charlie as "Carlo Bartolucci" until he  tells them that he now goes by the name "Charlie Barret." During the  1970s "Nick The Nose" flashback scene, however, Nick refers to him  as "Charlie" instead of "Carlo." As the events in the flashback  sequence had taken place some 20 years before, Nick would have  referred to him as "Carlo" since Charlies name change had not yet  taken place.
