They were on a mission. Apparently, they always were nowadays. Everyone just dragged Lucy along; sometimes she even fought wildly, but in the end, she was always the weaker one.
This time, they were fighting some huge monster that was terrorizing a village up in the mountains. Of course, the boys (especially Natsu) were exaggerating their powers. And that's how it happened.
Natsu was throwing fire wildly around him and didn't see one of the fireballs hit the stone shelf above her. In horror Lucy looked up just in time to see the rocks crashing down on her.
No one noticed she wasn't anywhere, seeing she wasn't much help in the actual battle. But just as Natsu threw the finishing blow, he called for her.
"Lucy! Did you see that? I totally-"
Normally by now, she would be all over him, yelling at him to be more careful or to stop being so prideful…
Something was wrong.
Natsu looked around himself in panic now as he started calling her name. Gray and Erza quickly caught on and started calling for her too.
Eventually, Erza saw a hand sticking up from under some tumbled rocks and swiftly pulled away the closest rocks as she yelled at the boys to help her.
When they finally got Lucy out, they all winced at her state. She was covered in bruises, blood and dirt. Erza recovered fastest and slapped Gray to wake him from the shock. Gray blinked, before seeing Lucy again and quickly making some ice for her head. Erza nodded in thanks before running into the village and calling for medical care.
Gray stood up and tried to drag Natsu up from the ground, but soon realized he was frozen to the spot. He took a closer look onto his face and saw shock in his eyes. Gray just sighed and waved his hand in front of Natsu's face. When he wouldn't snap out of it, Gray simply grabbed Natsu by the scruff of his neck and dragged him back.
