Agreed. I don't think Shanks is a shady guy although it would be interesting if he's one. This chapter made it seem like he doesn't have any ulterior motives but he does aim for OP, so it's possible we'd see him compete with Luffy for the PK title even if he's not a bad guy.
I presume he went there to see how Luffy's doing and then decided to turn back once he made sure he won and is doing fine.
Then it makes no sense that he suddenly decided to go back.
