@fapfapfap:
Wano arc is still being setup. Yeah things don't look particularly good for Carrot's chances at the moment but we're still early in the arc. Let's not pretend like we know how the entire arc will play out.
Honestly, this is as valid as saying "Bon Clay can still show up and shake things up. LEt's not pretend like we know how the entire arc will play out".
She very clearly hasn't been shown in the same respect the rest of the crew has. A good bunch of people hoping for her to join in Tottoland pointed to things like Wano, her being with the rest of the crew as an indication of her joining.
She hasn't interacted with ANY of the crew since being on Wano, and especially any of the crew that weren't in Whole Cake.
And honestly, the more important indication(though it doesn't sound important) is that she hasn't gotten a "wano name".
She's not undercover like the ENTIRE crew. She hasn't interacted with any of them. She's currently grouped with the rest of the minks. Hell, she's not even with Chopper.
At this point in the game, anyone claiming Carrot has a stake in still joining the crew has as much validity as saying Bartolomeo will join.
There's no reason for Oda to sideline a character that has been around half the crew for two years real time, only to somehow bring her back into the fold with the main characters.
Whether she sets out on her own, revives the Nox Pirates as a Strawhat Grand Fleet, or just stayes on Zou, it's abundtly apparent she's not joining the crew.
If the argument for her joining has come down to only "well, we'll see how Wano goes", she's in Perona territory.
"Perona is with Zoro, that will be her connection to the rest of the crew as she develops a relationship with the rest of them"
"Carrot is with Chopper, that will be her connection to the rest of the crew as she develops a relationship with the rest of them"
"Perona has a viable ability, her Fruit would let her be the lookout for the crew"
"Carrot has viable jumping ability. Her mink abilities and standing on the mast will let her be the lookout for the crew"
Not to mention no emotional investment in her joining. We've had NO mention of her dealing with Pedro's "death" since it happened. No "Franky Family moment" of her fellow minks telling her she belongs with the Strawhats, or even slightly dealing with her experiences with the Strawhats.
Wano still "being set up" isn't an excuse to still speculate that somehow Oda will do a full 180 on how he's written Carrot.
