ok...
I think TAC and Bogard's interaction isn't as suspicious as Law is making it look, they're just talking and trying to create activity. And that also applies to Law, I think he may be over-analyzing but he is just trying to find clues - any clue - from the minimal activity happening.
As for Playa saying that he wants revenge, I think this is just banter/a joke, unless if this is some 4D chess move then it's completely beyond me.
