Some people shouldn't have the ability to speak.
Anyway. If Sanji is carrying Nami bridal AGAIN, after last chapter, then Oda clearly has a favorite couple he doesn't say.
Bridal carry is a romantic gesture. Nami is the only one Sanji has bridal carried (aside from Bonney, but she's a kid and he did it in the spur of the moment trying to get her away from the enemy.) In actually having time to decide how to carry a girl, Sanji has only carried Nami like that.
The anime made him carry Pudding that way, Oda had him just throw Pudding over the shoulder in the manga, like Zoro did Tashigi. Viola was also a different carry.
Nami is always special.
