Just to clarify, Percy didn't kill the grievers right away because he didn't want to reveal his demi-godness to the Gladers quite yet.
Also, to dingo027, I'll try to make this story satisfactorily different from others.
I do not own Percy Jackson or The Maze Runner. All rights go to their respective owners.
'CRAP!' Percy screamed in his head. I was going to tell the Gladers, but not this soon.'
The two grievers closed in slowly, as if gloating their victory.
"What do we do?" Thomas asked.
"What can we do?" Minho responded.
Percy's head was rapidly twisting side to side, lookin for something, anything he could use. He wasn't even sure Riptide would work on the grievers.
He was just about to give up, when a glimmer of light caught his eye.
Next to the wall of the dead end, sitting there like a godsend A/N get it?, was a puddle.
"Go up against the wall." Percy said.
"Perc-"
"GET, against the wall." Percy commanded.
Thomas and Minho quickly obeyed, going as far back as they could.
"What's he doing?" Thomas whispered.
"I have no idea." Minho whispered back.
Percy put his hands at his sides and closed his eyes, concentrating. The grievers continued closer, one falling behind the other.
Percy stood like that for a couple seconds. And just when the lead griever lifted its leg to stab it into Percy, he opened his eyes.
The griever thrust down its leg and Percy dogged out of the way, right next to the puddle.
When Percy turned his head, Thomas and Minho gasped. Percy's eyes were glowing white, with a sea green around the edges. And the sea green was 'misting off' of his eyes in the corners.
The grievers turned to Percy, slightly irritated, and rushed towards him.
Percy lifted his hands, and two tendrils of water seeped out of the puddle. The grievers got close again and Percy made the ends of the tendrils pointed and turned them to ice.
The closer griever jumped at Percy and he shot the tendril on his right straight through it. From chest to back. The griever let out a blood-curdling, demonic screach. The other griever lunged at Percy. He quickly pulled the right tendril out of the first griever and swiped the left one at the second, adding ice spikes to the side. The left tendril slammed into the griever, driving the spikes into it.
The grotesque creature flew through the air, crashing into the ground as the griever's dieing cries echoed throughout the corridors of the maze.
Percy looked at Thomas and Minho's white, horror-stricken faces. Percy opened his mouth to say something when he felt a tingle in the back of his neck.
He jumped forward and rolled, taking all the water from the puddle with him. He quickly twisted around just in time to see a griever land right where he had been a split second before. He looked up and saw about six other grievers either climbing over the edge of the wall, or climbing down it. Drawn to the sound of two of their brethren dieing.
The puddle didn't contain that much water in the first place, and Percy didn't want to use too much too quick. He quickly stabbed the newly landed griever and motioned for Thomas and Minho to follow him.
"Quick! Run!" Percy yelled, running down the corridor they came from.
He turned the first corner he came to and nearly tumbled off the edge of some sort of cliff.
He heard the sound of running and saw Thomas and Minho sprinting at full speed towards him.
He backed up and used the puddle-water (that had been in a large blob behind his back) to make an ice-bridge across the chasm.
He ran over it immediately and stopped on the other side, looking in the direction of his two companions, who had stopped at the beginning of the ice-bridge. "COME ON!" He yelled, gesturing for them to cross.
They ran over quickly and continued running, only to stop when they noticed Percy wasn't with them.
Percy was standing at the end of the bridge, with two grievers rushing across, and the other four not far behind.
"PERCY RUN!" Minho screamed. Only for his command to remain unheeded.
When the third griever was fully on the bridge, and the first was almost across, Percy thrust his left arm out, and melted the ice, quickly gathering the frigid water back into a hovering blob.
The first three fell into the abyss, while the fourth, which was going full speed towards the cliff, simply jumped when it reached the drop-off. It almost reached the other side, but fell short and slammed into the other side of the chasm wall, and soon started climbing.
The final two grievers watched their brother and followed his example.
Percy looked over the edge and saw them climbing up. 'It'll take them awhile to reach the top.' Percy thought.
Percy jogged over to Thomas and Minho. "Now let's go." he said.
They continued at a jog for a couple minutes before Percy noticed Thomas and Minho often glancing at him stangely.
"What?" He asked.
"Oh, it's nothing," Minho started. "except for the fact that you just controlled a puddle to not just hold back one griever, but to kill not one, not two, but six grievers. I'm pretty sure anyone would look at you weird if they witnessed you do that."
"Plus the fact that your eyes are glowing like flashlights and you've got a blob of water floating behind you."
Percy glanced behind him, not even realizing he was still carrying the water.
"Oh." He smartly replied.
"You've got a lot to explain, Jellybean."
"I suppose so."
They continued jogging, with Minho in the lead, until they reached the Doors.
"It'll be sunrise soon." Thomas said, noticing the lightening sky.
"Yeah, then we can get out of this hellhole." Minho joked
'You have no idea what a hellhole is. Percy thought darkly.
"Also, Percy," Thomas said. "you should probably turn off your glowy eyes and put the water... somewhere, before the Doors open."
"Heh, that's probably a good idea."
Percy turned away from the Doors and slowly lifted his arms, palms down.
He then jerked his arms down and the water soon became a wet stain on the stone walls and floor.
He closed his eyes for a second. When he opened them, the glow had faded.
"How the shuck do you even do that?" Minho asked.
"Like you said, I've got a lot to explain."
They stood there for a couple minutes, and were able to see the slightest bit of sunrise light coming over the walls.
Thomas suddenly remembered an important someone who was, hopefully, still hanging in the vines.
"We have to get Alby!" He yelled, before rapidly sprinting off in Alby's direction.
"Thomas, wait up!" Minho yelled, running after him.
Percy stood there for a second, inhaled deeply, sighed, and started jogging after them.

Percy jogged the (thankfully) memorized route, and was almost to where Alby was when he heard an all too familiar screach.
Percy rushed forward and turned a corner, only to find Thomas and Minho, with two grievers behind them, and one between him and the pair. They were trapped, with no way out. And Percy had just thrown away his only water.

And that's the end of chapter seven.
