The attempted hit on Torrio was engineered by Hymie Weiss, who succeeded Dion O'Banion as head of the Northsiders, in revenge for O'Banion's assassination.
That's pretty much what I thought. The show made it sound that Torrio thought that Al Capone was behind the attempt on his life. Unless, Torrio was just saying that as a ploy to get Nucky to feel close to him. Hmmmmm.
