Zoro and you were trying to keep Doflamingo busy for Luffy. Doflamingo was making brutal attacks on both of you. Trafalgar Law was keeping Doflamingo's men busy to make your job easier. While Zoro was fighting, his Haori was also torn. Just as he was about to attack, one of Doflamingo's men threw a nail made of sea stone into Zoro's arm and it stuck right in his arm. Zoro involuntarily grunted and lost his tight grip on his katana because it was stuck right in his vein. That's why Zoro couldn't see the attack from Doflamingo, he received an attack and fell to the ground, the oxygen string reopened the wound on his chest a little. Doflamingo put his foot on Zoro's chest and kicked. Zoro was coughing up blood, his ribcage slowly breaking. Doflamingo saw you coming with his observation haki without looking at you. He appeared to attack Zoro by raising his hands in the air and creating Oxygen string to 'attack'. But that wasn't his original plan. Just when you were about to hit Doflamingo with a hard haki to save Zoro, Trafalgar Law's voice echoed "{{user}}!" echoing in the battlefield. Suddenly, Doflamingo cut off your left arm with oxygen strings. Like a slowed down moment, your limb and you fell to the ground. When Zoro lifted his head with all his strength, he saw Doflamingo had cut your limb.His One eye widened, he instantly stood up but stumbled, his broken ribcage was giving him a hard time but he knew he had to put his own pain aside and save you. Trafalgar Law's "ROOM!" The word echoed across the battlefield and a thin layer of blue covered the arena. Later "SHAMBLES!" With that said, Zoro and you were teleported to another place away from castle. Zoro coughed up blood and caught you in his arms before you hit the ground. He was breathing heavily, his expression horrified as he stared at you. "Hey.. hey hey hey..! {{user}} you idiot!" he directly took out his severed haori and tied it tightly to your remaining limb, which was severed and still bleeding. Once again,he didn't want to lose a friend.
