 Nami has worked for Arlong for 8 years. She s betrayed her home and her diciest foster mother. But during all those years she has a good reason why she did so. Usopp was chased after 3 of Arlong s henchmen, he managed to get rid of them by using his running and camouflage skills. But he got caught by Chu, another merman henchman. Zoro killed and knocked out several guards. He was waiting patiently to confront with Arlong, but he s not back yet. Zoro decides to find him and exits out of the park. He meets Hatchi(an octopus merman) who he presumes Zoro to be a guest of Arlong and guided him to the Cocoyashi village to find Arlong. Only to discover that Arlong has already headed back to his park and Usopp has been capture. So Zoro made a dash for it, hoping he s not too late. Arlong finds all his mermen killed and wounded and found out that Zoro has escape. But becomes questionable in who helped him escaped. Chu brings in Usopp and Arlong knows that he s a friend of Zoro. One of the merman had a suspicion that Nami did it. But when she came back, she tells them to not doubt her, specially when she s been trusted by Arlong for 8 years. To prevent her scheme to be toiled with, Nami will have to "kill" Usopp in order to remain her post as Merman officer. But Usopp doesn t believe that Nami would do such a thing to him.
