Wasn't the Scoppa brothers at odds with each other when Silva shot at one of them? Or am I thinking of someone else?

This is a huge hit in terms of power and drugs in Montreal. I think this could be the first hit since Leonardo Rizzuto got out of jail? Or at least the first major hit? This could swing things for sure as I think they are still in power in Montreal (meaning Sollecito/Rizzuto)
