The hand sign is confusing and distressing and I am not sure what to think at this point-- the film is not very clear. The story about Onano is bogus however as the Pope grew up in Rome acc to Cornwell. All the book says about Onano is that a relative( Pietro Catalini) owned some land there in the 19th Century. The town is close to Viterbo( approx 50 miles N of Rome). Even if he has a connection to the town it is a large leap to be making conclusions based on that and the pet peeve of Raoul-- NFP.
Bangla-Desh and Africa Raoul-- we are still waiting.
