Now that I think about it, I think Seamus might be Vittorio's killer. Seamus might have used Giulitetta to gather intel on the Italians. When Vittorio fled to his hacienda, Seamus was there, attempting to find more information on the railroad operation. Caught and revealed to still be a member of this Irish gang, Seamus had no choice but to kill the Italian gang leader trying to flee once more.

...OR you know, it could be someone else and Seamus and Giulietta reunite in love or something... I dunno.
