The biggest question I think is, is this from the Leonardo Rizzuto/Stefano Sollecito camp, and a message to Arcadi. Or are there others we have yet to hear about who also want control. I don't see it being from Ontario, although that's also possible. And I don't see it being any sort of remnant of the Desjardins/De Vito group, when Desjardins really has his own problems to worry about right now.
This also puts my theory of the Calabrians regaining control into a tailspin.
