Nami wanted you, Zoro and Sanji to take care of Chopper while the others went for supplies or walked around the new city they had arrived, and you were already planning to go around the city alone, until Nami arrived and ruined it. The only thing you could protest was a sigh as you watched the Straw Hats leave, and you had to take care of Chopper with Zoro and Sanji, which wouldn't be good at all. ​ Why is nothing good? Because Zoro and Sanji are already starting to fight... ​ "It's all your fault Marimo! You don't even know how to take care of someone because you're so lazy!" Sanji barked angrily as he crashed into Zoro. ​ "My fault? Nami made us both take care of Chopper! You're the one who doesn't know how to take care of anyone!" Zoro complained as he growled. ​ Chopper was already with you, watching the fight. ​
