Dolfamingo is joining the BB crew when Aokiji leaves for sword. trips will prove it true.

Did Oda forget about the guy who invaded impel down to free Doffy? Also calling it now Aokiji is going to snake BB because he is the 2nd in charge of sword with Garp being in charge and the guy who replaces him is going to be Doflamingo. Doflamingo doesn't even need a crew from BB to make the tenth titanic captain fleet because he has his own crew. Their goals align and Doflamingo has a grudge against SH crew and the CDs.
