I think this whole situation is weird too. But i guess joker can't risk for Caesar to fall into the hands of somebody else.
And olso, why would Law just give Caesar back to Joker? Something is not right here.I see 2 possebilitys:
- Law somehow gets the marines to arrest Caesar and make Joker start a fight with fujitora (Or something in these lines).
- Mabe Law will use Shambles on Caesar and switch his mind with somebody else so Jokers thinks he's taking Caesar back home, but is acctually returning with somebody else in Caesar's body (Possible infiltration mission?).
An infiltration would be interesting but I doubt it's gonna happen cause that person will need to escape afterwards.
But i find the possibility of shambles very interesting here.
That's a very good scenario if it happened but I don't think so, they should have done it buy now when they still in the ship so the other person can train on how to behave so it cant be discover easily bu Joker and it should have been hilarious if Ussop is the one doing the job :D
