I highly doubt Luffy is going to interfere like some of you are predicting. I mean Luffy in his current state, with haki and all, has no reason to run from Smoker. Zoro could take Law and Tashigi on at the same time. Robin and Usoppu would deal with the G5 marines. If Luffy showed up, that's pretty much all that'll happen. Not to mention Luffy is yet to deal with the "Boss" and ask him to join his crew.
