My point being there would be a meaning if she was to become a relevant character by a decent margin which she won't be. She will be irrelevant for most part if she doesn't join. For example you will feel the emptiness of law also
So now that Yamato (she doesn't join), Tama (already rejected by Luffy), Momo (he has become Shogun) and Kinemon (stays with Tsuru) have been ruled out as nakama, only Carrot and Chimney remain as real candidates.
If Carrot doesn't appear in 1057, it's done then. She sneaked in the Sunny.
