Here's a bizzare question...
Remember in VA when Dimitri told Rose that he beat up his father for hitting his mother? But we never read who is father was. Also, in SB, Dimitri knew who Abe was and warned Rose to stay away from him but D never said why. What if Abe is D father too? Abe got around. That would be a huge twist. Also, while in prison. D probably heard that Abe is Rose's dad, so maybe that's why he is pushing Rose away-besause he is her half-brother?? just a crazy thought.
