Meh, y'all acting like Oda can't come out the cut with some depressing backstory or expand on her dreams (Though I thought her wanting to see the world and being sick of being on the island was okay, not everything has to be grandiose or heartbreaking, though I'll concede there's obviously a trend for it) whenever he feels like it, as if we didn't just get yet another one with Sanji not too long ago after all these years lol. Now yea, that is not the same thing of course, but all I'm saying is, I'm happy to be patient and see what happens after this arc. There's a lot going on since the timeskip, so it wouldn't be too out there for Oda to take his time to introducing a new member. After all, we're only just now getting Jinbe. Furthermore, it's been 9 years since someone joined, and there's also been a timeskip since then. I wouldn't necessarily be surprised if after all this time Oda decided a more roundabout approach to eventually making her a member, or at the very least stop caring about each member needing a "proper role". (Because honestly, how many roles are left to fill, I'm genuinely curious lol)
In the end though, I don't want to come off as utterly reaching, or act like some desperate Monet fan that will never give up hope, so I try not to get too crazy with the Carrot love. All I know is, Oda dangled the bait right in front of us with him randomly making her a stowaway, and having a personality that jives quite well with the rest of the crew.
So I blame him.
