After his brief re-appearance at punk hazard, we get the idea that he is "in" with the underground....
he does tell smoker he is still the same guy....
so i can get the feeling that he is doing the whole green hornet type deal... pretending to be a bad guy to get in with them, then destroying who they are afterwards... kinda like the opposite of what vergo did...
i also kinda get the feeling that he is doing good, by his standards of good... so like, if it means helping pirates then he would help...
so one would assume, that after leaving punk hazard, he would make his way to dressrosa... weather its to help luffy, or jus to take dolfy's head....
what are your thoughts?
