Gray knelt down and looked and Natsu's body for fatal wounds none were life threatening. He pulled out the sword an froze where there were serious bleeding.
"That's all I can do," he said standing up, "We'll have to go back to the guild if he's going to live."
"Yes let's." Erza agreed, "We can't risk the losing a member just for a job."
"If it was this dangerous then it should have been an S-class job." Lucy said.
"It was probably a set up to get a certain person back and that person turned out to be him."
Gray carried Natsu to the train station that morning. Kireba, resisting the urge to use a serpent to fly back, rode the train with them. She sat on the other side of the train car with Natsu in front of her.
Everyone was silent on the way back. Kireba was trying to hiding her motion sickness, but was still was able to move. Halfway back, she started to melt Gray's ice. He noticed after she melted the ice on his leg. He watched her in silence seeing a gleam of green in the melted ice. Once she evaporated the water, there wasn't even a scar, Natsu's leg was as good as new. She continued to do it on the other wounds and healed him completely. He was still unconscious, but wasn't in danger anymore. Kireba noticed Gray was watching her after she was finished. Lucy and Erza were looking out the window the whole time. Gray was impressed to find someone who could melt his ice without fire. They reached Magnolia shortly after. Gray carried Natsu the rest of the way.
Once they reached the guild everyone stopped and stared at them as they walked by. Erza asked Mirajane if she could talk to Master Makarov, Gray took Natsu to the infirmary, and Lucy and Kireba just waited to see if Natsu was okay.
"It's so silent all of a sudden." Kireba said to Lucy.
"Well it's not common for Natsu to be carried all the way back here." She replied. "In fact, its never happened ever. Well on a job at least."
Kireba could only feel guilty for what happened. Natsu wouldn't be in his unconscious state if she hadn't joined, but being in a guild was her dream even as a child. She tried to think of something on the positive side, the happy side of life. Thinking of happiness reminded her of the blue cat she met the other day, the cat Natsu was partnered with was missing.
"Hey have you seen Natsu's cat anywhere?" Kireba asked.
"Oh, Happy? I haven't seen him lately. He's probably with Natsu." Lucy replied.
Kireba asked Mirajane where the infirmary was and went there by herself. When she got there all she could see were white beds and in one of those beds laid Natsu recovering from his current state. She looked around for Happy, but he was nowhere to be found. Before she left, she saw something about Happy. She heard Natsu's voice in it too. She turned to Natsu and thought to herself.
"That was something about Natsu then. He must know what happened to him."
As she got closer, the vision she became clearer. By the time she reached he bed, she saw everything that happened to Happy and saw who almost killed Natsu. The person's scent rose off of him. She left the guild hall determined to find Happy. She bought a simple cloak and headed back to Oak Town. The thing she couldn't get was why no one notice Happy's disappearance before.
