Thats providing Sanji even has any of the siblings powers. In the end it could be a simple case of he doesn't need it, that he was stronger without it.

Either way, the point wasn't Sanji was a reject in terms of power, the point is his father simply couldn't love Sanji unless he wasn't a reject. I wonder if the enhancements to the others will eventually turn sour (in a lot of series when enhancements come into play, a side effect occurs such as life span being shortened... But we've already played this card a few times in OP). The other possibility is Sanji may not be powerful, but the lack of power could turn out to his advantage in the enhancements turn out to have really bad consequences yet revealed.

I hardly doubt this will be an issue... In the end its more likely to turn out Sanji gets his power from his conviction or beliefs then it is anything else.

I just want to see his father turn around and have to eat crow... But I doubt it will happen. :-/
