Natsu looked on in shock as he saw Aquarius continue to fight Lucy. He couldn't believe it, and had a hard time wrapping his head around what just happened. Him and Gray were just trying to find their way out, when he lost track of Gray and Lucy(?) attacked him. The only thing is, this isn't Lucy. No way was it. It was Lucy's scent and body, but her mind was not hers. Lucy wouldn't just attack her friends this way. And, especially after seeing Aquarius, she would not try to fight back.
Natsu snapped out of his thoughts when he saw Lucy starting to grow tired of fighting Aquarius, however, Aquarius did not stop her attacks. She kept throwing her attack out, and wasn't letting up. Natsu knew he shouldn't intervene, but after hearing Lucy scream, he couldn't stop himself. Even though he knew this isn't really Lucy, it was still a part of her. And her scream tore him and hurt him in more ways than he thought. Hearing her scream once more from the relentless attacks, he ran in front of them and stood protectively above the nure-onna Lucy. Behind him, Lucy stared up at him in surprise. After the hits and torment she used on him, he was protecting her.
The part of Lucy that was still there, was able to let the memories flow in of all the times Natsu had saved her. The part of Lucy that was being controlled, tried to push all the memories back, but still let a few tears fall. Looking back up, she could see Natsu still standing above her in a protective stance. "What are you doing, boy? Move out of the way!" a furious Aquarius yelled. Natsu shook his head and let out a growl. "No, stop it! Can't you see this is still Lucy! You're hurting Luce!" he yelled desperately before covering himself in flames just in case Aquarius tried to get to Lucy. The mermaid let out an angry cry of frustration.
"You idiot, can't you see that's not Lucy! She's being controlled. She was just hurting you a moment ago." Natsu shook his head, not listening to a word Aquarius was saying. "Can't you see she's still there! There was hesitation in all of her attacks, on both me and you! And now look, can't you see? She's crying." Natsu let his flames dim a little bit so Aquarius could see past him and get a look at Lucy's face. "And how do we know she won't fully be taken over any minute now?" Aquarius asked. She was a little bit more calmer, but not much more. "We don't know. We just have to trust her." Natsu replied coldly. This made Aquarius furious once again. "You don't even know what will happen! We should at least knock her out to make sure!" the mermaid cried out. "Is this the first thing you'll do to Lucy after having you gone for so long? You're really just going to attack her?" Natsu questioned angrily.
Aqurius looked away at Natsu when he finished his questions. "I wished I didn't have to. But with these circumstances, what else can I do?" she questioned him. Natsu just gave her a glare in response. "You don't fight against her, you fight with her. Not the Lucy that's being controlled, but our Lucy!" Natsu exclaimed. Behind Natsu, Lucy sat still crying. However, she was determined to fight for control of herself and to stop harming her friends.
(A/N: This isn't the best it could be, but since the next chapter of the 100 year quest doesn't come out until tomorrow, this is all I can do for this. Sorry if it seems short or not interesting, I'll try to rewrite it if I have time later on!)
