Another ten chapters since we saw Carrot, and just like last time, it seems very deliberate that she's being left out. There’s a point Oda's planning to make, and it has everything to do with Pedro's will.
There are three main points Pedro made:
1. Everyone has their moment to shine
2. Someday the importance of the Straw Hats and their connection to the dawn will be clear
3. Keep moving onward
Carrot needs to understand all of that before her arc can reach a satisfactory conclusion.
First, she has not had her time to shine. If, for example, that fleet battle was her time, there would be no reason to push her so hard now. She could have beaten Peros with Sulong, he admitted that, and that would have gotten the revenge she wanted and perhaps satisfied her. But instead she failed, and Peros twisted the knife by saying to just run home to Zou. She needs her moment now, not in the past. Revenge was not the answer Oda had in mind, or else she would have gotten it.
Second, she knows there's a reason Pedro gave up his life beyond just saving them in WCI. She knows what Pedro said of the dawn, the centuries-long wait and the Straw Hats being vital to that. But she has yet to understand the true meaning of his words and actions. She's still thinking in very personal terms, that Pedro died and the enemy pirates are to blame, that the Straw Hats are simply her friends she wants to help and that she wants to have an adventure. What Pedro wanted her to have was a clear goal, a reason to sail and help her friends to bring that dawn he longed for.
Which comes to the final point, the one Carrot has thought back on twice, before and after the fight with Peros. She has not yet moved forward. She's been fixated on Pedro's death and going after anyone she can lash out at, just like when she charged at Katakuri. Back then, Luffy broke through to her in her darkest moment. He gave her a reason to move forward, to protect the ship while he took the burden of fighting Katakuri. Jinbe followed that up with a reminder that Pedro did what he had to do with no regrets, and they needed to do the same. Carrot had the maturity to absolve Sanji when he was blaming himself. Deep down, she knows that Pedro's death is bigger than any one person.
Soon, she's going to put that all together and truly have her moment, move forward and make it clear whether her future is with the Straw Hats or not. And I'm still betting that it is.
