How will Luffy escape from Mirror World?

How will luffy escape from that Mirror World if all the mirror in Thousand Sunny was broken into pieces..?

Yeah..
The question is how Luffy will escape from Mirror World..
But..
The exact question is how will Luffy escape from Katakuri..
For me..
I think Oda is buying us time because he want to set a fight between Katakuri & Sanji..
Why would I thinking about this fight..?
The reasons that I could thinking about this are:
i) Sanji need to shine in this arc..
- In Dressrosa, Zoro shown us his Armament Haki to fight Pica, one of the officer for Doflamingo. We all know that Sanji is not there during the fight because he need to go to Zou first along with Nami, Chopper, Brooke, Momonosuke & Caeser Clown.. Oda separated Strawhat Pirates into two group so that Zoro will shine in Dressrosa.. So, I bet in WCI arc, Oda would matches Sanji to fight Katakuri (or one of Sweet Commander).. Since Luffy beat up Cracker.. And Oda mentioned that Katakuri got the highest bounty.. I think that the real opponent for Katakuri is Sanji.. During this fight, Oda will show us the power of Observation Haki as Sanji & Katakuri a.k.a Dogtooth also one of the Observation Haki users.. The twist is will Sanji fight Dogtooth since he's also the DF user.. Flashback to Enies Lobby arc, on the way to go there from Water 7, Sanji fight someone that use DF that make him able to use spaghetti in the fight.. So this time, Sanji will face the same situation when he face Katakuri.. We all know that Katakuri's DF is Mochi.. Mochi is also one of the dishes or food.. This is such an interesting fight for Sanji.. Will he uses his hands in this fight too..?
- So the important thing to highlight are:-
a) Sanji will shines in WCI arc as Zoro shines in Dressrosa arc fighting against Pica..
b) The Observation Haki battle between Sanji & Katakuri might be the interesting fight..
c) Sanji hates food been wasted as Katakuri's DF is Mochi..

ii) The fight is indeed a reason for Katakuri to let Pudding choose her own 'freedom'..
- In my previous post, I mentioned that Katakuri & Sanji will fight and Katakuri want to know that Sanji have all the criteria to make Pudding safe and happy.. As the brother for Pudding, he will allow Pudding to choose whether she want to stay or go with Sanji.. So Pudding would decide on that matter.. She want to be free like Lola.. She want to fall in love to a guy not some arranged/force marriage..

So what you guys think on this post..?
