The scenario does seem a bit contrived at this point. Sanji fighting off Fullbody on his own and becoming a party member evens it out, though.

Humiliating a jackass in front of his date, getting combat, gaining a new crew member, I see nothing wrong with this plan. Yep, nothing but good can come of this.

...And obviously Fullbody is the main villain of this campaign. I don't see a reason to expect any more surprises.

None at all. A surprise fourth party would just be silly.

And they can exact revenge for the roach!

My head canon says it was related to The Bug.

The way Fullbody go's down here is so much better than the anime!

Also, funfact: one of Sanji's berserkbuttons is spoiling foot - don't you dare do that when he is around, or else...

Yeah. He seriously puts his foot down when it comes to this stuff.

I'd say hitting a lady is a much bigger berserk button for him...

Nah. Don't forget that he mainly protects women out of chivalry, while his reaction to wasted food is more of the subconscious flavor,given Sanji's backstory.
