In last page of recent chp luffy was shown to do something in dressrosa instead of running back, what i''ll think is he will shout to Rebecca that he is taking kyros with him on his ship. Kyros was shown with so much feats of joining the crew. And luffy wasn't paying attention to his talks, but maybe he got the clue of him want to leave dressrosa and he knows the sad story of kyros being a toy soldier and Rebecca's past. So maybe he will shout to Rebecca for taking his father and will ask for her permission of whether being okay by her or not aa he knows that returning of kyros means so much for whole riku family... He will definitely won't fight Fuji as he is injured right now and not strong enough and will also shout of his promise being completely fullfiled to Rebecca.
