o_o Gambino is the only sick genius that could come up with something like that xD Or maybe it was just strange circumstances '_' Gambino, perhaps, had a replica of his old mansion on the first couple of floors of his tower, and seated on the top was the one he now has in Durem surprised And when it fell, the two mansions just came into palce o_o Though, I imagine the only in Durem is super 'eff'd up inside sweatdrop
Evidently, it isn't the end of the plot, however I'm not so sure that they'll all be coming back. Mark my words, though, we will find out whether Gambino was assassinated or not, and by who, or whether it was just another scheme.
