I should add that while yes, I play Robin as sticking mostly to canon, I also portray her as my own interpretation of the character, and that is a mother-type to the rest of the crew.
I have always seen her as such after she joined the Straw Hats, and I likely always will. She’s been saved by them, and they’re truly a home for her.
And while yes I do ship her with some of the other members that aren’t Franky that’s not going to stop me from still seeing her as a protector of her friends. They are the closest thing to a family she has anymore, and they’re the only ones that weren’t looking to turn her in, and that means more to her than anyone can ever imagine.
And while no, she’s not going to go around saying things like “yo das my child” and the like, she does still have an instinct in her to make certain that their safety comes before her own, and that everyone is cared for.
