Who do you think would have the most interesting dynamic with Alex, that we haven't seen interact with her. Also, which dynamic you have written with her, did you enjoy the most?
I have such a clear and vivid answer to this question and it's going to be a major part of the sequel and I'm devastated to tell you that at this point, I can't tell you guys who it is. However it is possible that this is a character I can see a romantic-subplot with....
But I think the thing I love most is writing her dynamic with a bunch of different people back to back because she's so different depending on who she's with. Every moment between her and Whitebeard is a joy to write, they've really run the full spectrum of moments together from the adorable to frustrating to heartbreaking and back to intensely sweet. I also love the dynamic between her and Luffy, but it's funny because that wasn't really our Alex (it was the closest she could get to her original personality, which isn't really her anymore after a decade inside One Piece) It's going to be so fun to write their new dynamic now that Luffy knows the part of her she was hiding.
