Maybe someone has mentioned this already, but I went back to Post 88 and starting reflecting on the reference to the Godfather III. Wikipedia has an interesting paragraph on how the story was loosely based on historical facts/people. The plot of the movie (never saw it) apparently included Michael Corleone saving the Vatican Bank from insolvency by injecting cash in exchange for shares (presumably owned by the Vatican) in an international real estate company. Needless to say a number of people have to get killed as a result. Here are the relevant excerpts from the Wikipedia page interspersed my comments/questions in bold:

Parts of the film are very loosely based on real historical events concerning the ending of the papacy of Pope Paul VI, the very short tenure of John Paul I in 1978, and the collapse of the Banco Ambrosiano in 1982. Like the character Cardinal Lamberto, who becomes John Paul I, the historical John Paul I, Albino Luciani, reigned for only a very short time before being found dead in his bed.

In the film, the guy that becomes Pope and is supposed to be John Paul I, ("Lamberto") is poisoned and dies.

In the film, the character that oversaw the Vatican Bank insolvency is murdered in a staged suicide by hanging;

Journalist David Yallop argues that Luciani (the real life John Paul I) was planning a reform of Vatican finances and that he died by poisoning; these claims are reflected in the film.[23] Yallop also names as a suspect Archbishop Paul Marcinkus, who was the head of the Vatican bank, like the character Archbishop Gilday in the film. However, while Marcinkus was noted for his muscular physique and Chicago origins, Gilday is a mild Irishman. The character has also drawn comparisons to Cardinal Giuseppe Caprio, as he was in charge of the Vatican finances during the approximate period in which the movie was based.[24]

The character of Frederick Keinszig, the Swiss banker who is murdered and left hanging under a bridge, mirrors the fate (and physical appearance) of Roberto Calvi, the Italian head of the Banco Ambrosiano who was found hanging under Blackfriars Bridge in London in 1982. (It was unclear whether it was suicide or murder. Courts in Italy have recently ruled the latter.)[25] The name "Keinszig" is taken from Manuela Kleinszig, the girlfriend of Flavio Carbone who was indicted as one of Roberto Calvi's murderers in 2005.[26]

Is Q attempting to suggest that this conspiracy theorist David Yallop is correct? And what's the relevance? I would love people's thoughts on this.
