Sanji v. Queen is more likely, Queen knows Judge personally and reflected on it.
Jack potentially could encounter Yamato soon
Yeah, I'm putting Yamato vs either Jack or Smoothie (when she shows up LOL)
Oda can plot "daughter of Yonko Kaido vs Daughter of Yonko Big Mom"
However, with Jack.... I have this theory that Jack is in LOVE with Yamato
I feel that both are around the SAME AGE... and I could write a plot between them that Yamato ALWAYS rejected Jack who showed sign of interest towards Yamato... and I feel part of why Jack is like a GOOD BOY towards Kaido most of the time is because of his affection to Yamato... I feel he both, idolizes Kaido and has a soft spot for Yamato
So, if that is in anyway close to the truth, Jack might face Yamato..
But I have big feeling that it will end as:
Yamato vs Smoothie
Yamato inherited some toughness from her father
I wonder if Smoothie is the same, maybe she inherited a tough body like her mom. And that's what makes her Commander level
