I have always find it interesting that Smoker grew in a very tough and harsh environment like Luffy. The baseball club is very reminiscent of his Jitte. Clearly, He always had that tough attitude, and that sense of Justice. I wonder if its his dog or one that he protected. I usually don't like flashbacks but I would not mind seeing one for Smoker
Hina clearly was raised in a more privilege background and always had a fascination for cages liker her DF power. I find it interesting that someone from the high society would love someone like Smoker who grew up in the gutter, and being a troublemaker. I guess opposites do attract each other
Unsurprisingly, Tashigi has always been like this. She is literally a sword passionate from her childhood. In addition, she started being a swordsman when she was little based on the bamboo sword used for training. I remember what she said to Zoro (depending on your translation) " Know I have not picked this sword for fun(...) I have always lived my life being me and being only me !" .
I guess Tashigi was not lying to Marimo and has never sought to imitate Kuina. She has always been honest with him
