The killing of Giordano the strongman of the Rizzutos was probably also a warning to Arcadi.
Seems that way now don't it? I was interested in seeing which side he was on but when Giordano was killed right away and the fact that Arcadi seemed to stay loyal to Vito when he was away that they are all targets now. I don't see Arcadi going away quietly though. Isn't he still in prison after they put him back in after Giordano was killed?
