Actually the question for me is not what's going to happen!
It's "did they capture someone else other than Sanji?"
I've checked the translation for two sources... both sources has the line of "we captured ANOTHER warrior of justice"
So, it feels like they've been playing this act, and they have been capturing ANYONE who's tempted with their sense of protecting women....
So, the question, is it really an accurate translation here? does that mean Someone else womanizer like Sanji got caught too!?
If Drake was not in this chapter, I would have said it was him to set up their duo... but since it's not Drake... I wonder who could it be LOL
Or is it just bad translation!
I honestly would like to see someone VERY BIG SHOT being in that condition and we get surprised by him being on the island, getting captured for being a simp like Sanji LOL
But I think I should not think too much of it... maybe just bad translation
Also, a good plot by Oda to make Sanji get out easier is the shaking of the island give Sanji a moment to slip away, OR once the island lands on Flower Capital.... I think that's Oda's escape route for Sanji...
