@uniaka:
Only if she doesn't marry sanji and there won't be romance between them.
Oda said "No romance cause boys don't like it" like… 20 years ago. His attitude has shifted on it some since then, and he's had quite a few romances in the series now. And he has a daughter. Series is never going to turn into a shoujo series about nothing but relationships, but he's not going to leave out romance entirely when its a core human emotion and part of storytelling.
Even with his aversion to killing characters he still lets them die when the story demands it.
The main issue I see currently is that Pudding has shown no real "main character" traits in terms of abilities or being able to fight or anything, and she looks very, very much like Nami... And Oda's not going to drag around a useless crewmember for the next ten years. (The suggestion of them being engaged and marrying at series' end works for me, and it'll also tone down Sanji's worst traits some._
But then, she hasn't shown off her third eye yet either...
