I'm willing to expand on this sooner or later but just to keep it simple:
1) Shanks is evil and he is manipulating everyone since the beginning of the story.
2) Mihawk and Shanks are rivals just like Zoro and Sanji.
3) Shanks is too weak to be an opponent for Luffy at any time of a decent story and, at the same time, he is too important to be useless.
4) Mihawk has to go somewhere.
The wings of the (next) PK will have to protect Luffy from the evil duo: Mihawk and Shanks :cheers:
