He had been a tough one, she hat to admit, but she was glad he cared about her. She slowly remembered his progress, distrusting her guts when they first met, and she had surprised them all by exiting the cabin, after stealing Nami's clothes. He hadn't trusted her in the slightest then, but now, here he was defending her honor. She never quite understood it, but looking back, he had helped a lot in saving her at Enies Lobby, and even at the Sky Island it seemed his trust was in her was beginning to blossom.
She looked at him, with a smile, happy to know that she had fallen for this green haired idiot. He was telling about how she didn't have to do that. That she could make her own decisions, she was free to live, to a stupid marine captain who wanted her dead. She didn't know where the rest of the crew was, but she knew that they'd all agree with him That was why they had stormed Enies Lobby in the first place. Had she truly wanted to die, she figured Luffy would just leave, but he knew, as did everyone else, that she wanted to live. She hadn't seen his fights there, but she knew he had fought for her freedom, they all did.
Robin could defend herself, they knew that, but she also knew that these nakama of hers would defend her also. They were her friends, and they all knew it. They all trusted her, just as she trusted all of them. She just stood in awe of the swordsman as he slashed down the marine, though her face wouldn't show it. He was a great man, and she believed that he would become the greatest swordsman just like her captain would become King of the Pirates. They both were far fetched dreams, but hers was as well, and they were ready to help her achieve it.
After the battle, when they were all exhausted, and relaxing around the ship, Robin took a delicate hand, and carefully wiped the water droplets of rain off the swordsman's face. She held an umbrella over them with her devil fruit abilities, and she smiled sweetly, and gratefully at his sleeping face. his chest heaved with each breath he took. She was curious about his scar, as she ran her finger across it under his eye.
Finding peace in her surroundings, she rested her head on his shoulder and found herself drifting off to sleep. If she were at all honest with herself, she didn't know what she would have done if he died. If he had died on taking in Luffy's pain. She would forgive him, that was certain, she wouldn't want her captain to die either, and Zoro did make the right choice, she was sure of it. She was eternally grateful that his body had been strong enough to endure her captain's pain and his own. If she could go back in time to that moment, she probably wouldn't do anything differently, as much as that hurt her to admit.
She loved Zoro, and she wanted his dreams and aspirations to come true, no matter what, but she also knew Zoro, and she would always stand by his decisions. At least now. Now that she knew him more. Now that she had fallen for him. Now that she had spent time seeing what kind of person he is.
She felt a strong arm wrap around her, and she glanced up at Zoro's face, but he was still sleeping. Or at least appeared to be, she figured. She closed her eyes, and with a soft smile snuggled gently into his warm embrace. Sure, he still held Wado Ichimonji against his left shoulder, and his other two swords along with it. She could tell that sword was important to him, and briefly wondered about its origin, but the way he held her now, gave her much comfort, and slowly she drifted off to sleep.
