In the E.N.D

Chapter 4: What's wrong?

Erza's POV

After Natsu's great demostration, he walked to the tunnel where the Fairy Tail participants enter. But something didn't seem right. So I decided to go and check.

I arrive to the tunnel to see Natsu in his knees, leaning in the wall and with a hand in his head.

"Natsu!" I ran towards him and kneel beside him. "What's wrong? Are you ok?"

"Don't worry, I'm ok" he says with difficulty

"No, you're not. I'm taking you to the infirmay"

"I'm fine Erza!" His voice is the same as when he shouted at me yesterday.

"I'm sorry, but you're coming with me." I put my shoulder under his right arm and help him stand, he can barely stand, with his other hand he covers his left eye. I help him, and take him to the infirmary, I make him lay on a bed and go running for Wendy.

"What's wrong Erza-san?" Wendy says while I pull her through the tunnel.

"I need you to check on Natsu, he's not feeling good."

We arrive to the infirmary to see Natsu in pain. He's in fetal position and grabbing his head, he is in lot of pain.

"Natsu-san!" Wendy goes running to his side and starts healing him, but there is no change in Natsu.

"How is him?"

"I.... I sense nothing wrong with Natsu-san."

"What?!?!"

"Yes, he is healthy or that's what my magic says. I can't feel what's wrong with him."

"I'm going to look for the master, wait here and try to help him Wendy"

"Yes, Erza-san"

I run through the tunnel as fast as possible.

I don't understand what's wrong with him. Why is he in pain? I hope the master can help.

Half way I encounter the master.

"Master!"

"Erza, where is Natsu?"

"He's in the infirmary but we don't know what's wrong with him"

"I'll check on the boy, Makarov"

Polyuska (i don't know how it is written) appears, from behind me.

"Take me to the boy"

I guide her to the infirmary, when we enter the infirmary we see Natsu in the same position but he seems to be asleep.

"How is him?" Polyuska asks

"I don't know, he got inconcious because of the pain."

"Let me check" Polyuska sits beside Natsu, put her hand in top of him and start sensing him. "Wendy's right, there is nothing wrong with him, I can feel somthing inside but it could be nothing, dragon slayers have always something that I can't figure out. We must let him rest, and see how he gets."

"I'll take him the guild so he can rest better" I get closser and touch Natsu's arm "Auch! He's hot!"

I can't believe, Natsu's have always been hot, but now he's burning, like lava.

"Hot?" Wendy touches Natsu and takes her hand quickly. "His burning!"

"I don't understand what's happening to this boy, but we need to cool him down."

"I'll bring Gray" I say and walk out of the room.

What the hell is happening to Natsu?

I run and find Gray about to leave the complex.

"Gray, wait!"

"What is it Erza?"

"I need your help, Natsu is burning"

"Burning?"

"Yes, he seems to be sick and is burning like having great fever but we can't figure out how to cool him down."

"Ok, I'll go and help."

.....

Gray has been trying to cool down Natsu for more than 15 minutes but is not working.

"I can't cool him down, I'm using all my magic but it's not working."

Gray continues trying to cool Natsu down for another 30 min, nothing is working but suddenly Natsu opens his eyes.

"Why are you looking at me that way?" He asks as if nothing had happen.

"You don't remember anything?"

"Nope, I just remember burning all those monsters and then I was here."

"You scare me Natsu" I say and hug him, he's now at his normal temperature, warm as always.
