My opinion on Vito has changed drastically between this, and finding out Apalachin Meeting failure was really Magaddino's fault

What if:
Vito and Luciano's relationship really did sour a bit after the Havana Conference like we mostly thought
But then by the 1950's, a Costello/Adonis/Lansky faction tried pushing Luciano aside from what he built, so he used Vito as a missile against them

Again, not something I would of considered before seeing this haha
