After rising of the mirror holding Brulee captive, Charlotte Oven immediately recognizes that Pekoms is screening Luffy in his hairs.
Seeing the collapsed Luffy, Sanji instantly jumps into battle and tries to get away from Cacao by doing his Sky Walk, but unluckily for them, few different members of the Charlotte Family concern that some of them are capable of using the identical technique and pin them to the area. The Charlotte Family is too wide for the two of them to manage, but before Luffy and Sanji are overwhelmed someone else appears to save them.

It appears they have eventually made it out of Big Mom’s palace and are made for a major battle with the remains of the Charlotte Family members before the Whole Cake Island arc reaches its conclusion.
