HANK! HANK! Not the "Rocks"! Get away from the "Rocks"!
But I'm worried for no reason, JoJo is enjoyable like that, characters pay attention and don't overlook things even hinting that they might be in "danger". They "know" something's up.
This heist is of course not that easy. I would have thought that Rohan himself would prove to be a challenge, but it seems there's a third party involved, on top of the return of rock humans, that caught Rohan's fancy. Add to that the lack of professionalism of this young team (or ofc the fact that it's chap 3), shit is about to go wrong.
