Yeah, they will definitely be seen later on, and will more than likely make some type of distraction. I'm wondering if they will get caught again or will they be able to escape, my guess would be to escape because when Luffy and Ace are making their escape Whitebeard will probably appear out of nowhere.

I'm also wondering on the role that Crocodile is going to play soon, with seeing his hook numerous times and also Bon Clay wanting to see someone on level 5.
