(A/N: Second chapter in a day; here you all go. I swear it will pick up. If you haven't ever watched Ghost Adventures, I highly recommend it, whether or not you believe in ghosts. It's an entertaining show. I promise. Leave a review on this story if possible. Thank you!)

Leonardo looked down at the burly man, suddenly at a loss at what to do. Could they leave? Or would it send out a full blown investigation to who hurt this famous man? Would they even survive in the cold? He frowned, as he noticed blood gushing from his nostrils, down his neck, behind his perfected dark hair, and almost seeping into his dark long sleeved shirt. All four of the brothers jumped when a walkie-talkie sprang to life on the belt loop of the unconscious man's baggy jeans.

"Zak? Are you okay?" A voice came through on the other end, speaking in a new England accent that Mikey immediately recognized.

"That's… That's Nick Groff!" The youngest turtle was practically bouncing in his place in the room, and Raph gave his youngest brother an intense look in the eye.

"We have too much going on right now for you to fan-girling about some ghost show guy who could catch or us kill us! You need to calm down and…" The same voice cut him off the communication device.

"We're on our way. Aaron should be there any second. Hang tight, Zak." Nick's voice came through once more, sending the brothers into a panic. They set upon hiding with what they could, with the various pieces of debris lying around the room. Michelangelo found himself behind a stack of rotting drywall that was leaned against the wall. Raph and Leonardo were back-to-back, hiding expertly in the shadows. Donatello hid underneath an old bed frame. They heard more footsteps enter the room.

"Zak? Zak?!" The voice wasn't the familiar tone that they had heard over the walkie-talkie, causing the turtles to come to a conclusion that it was Aaron. The bald, tall man entered the room, and almost tossed his camera aside once he took out a flashlight and shined the beam onto his fallen friend. "Nick! Get over here, now!" He called out, before lightly tapping Zak's cheek with the palm of his hand. "Come on, bro… You got to wake up…" He murmured to himself, before his other, equally concerned friend entered the room. "Do you have any first aid?" Nick pulled at a backpack on his back, and Mikey peeked around the foul smelling drywall to see the genuine fear on the two men's faces. He frowned; he had watched the show for years. He knew that both Aaron and Nick considered Zak to be one of their best friends, and it was insane to see the three of them in person, and showing the deep amount of care for each other in real life as they did in the show. Then, he hadn't realized how rotten the dry wall really was.

A piece of the material broke and fell onto the hollow ground with a disgusting mixture of a thud and a squish. Aaron immediately sent his flashlight in the direction of the noise, his hands trembling with the motion.

"Is there somebody here with us?" He called out into the darkness. His hand shakily held a small, black device in Mikey's direction. The orange masked turtle silently swallowed the lump in his throat.

"You hurt our friend, Zak. Was it you, Georgia?" Nick spoke up, his voice strong and threatening. "Show yourself! You had enough energy to hurt our friend; you should have plenty to show yourself!" His face was red with anger, and Leonardo watched the man warily as both the humans were still facing the direction of his youngest brother. He noticed Raph still tense and watching the men as well, but he couldn't tell if Donatello was in the same position.

"…Nick?" A deep, groggy voice mumbled from the ground. The attention that was previously placed on Michelangelo was placed on the formerly unconscious Zak.

"Zak! What happened, man?" Aaron questioned. The said man winced as a harsh headache came across his temples.

"I heard… Voices." He slowly spoke quietly. "I went… And I saw… Four. One hit me. Twice… I think." His story was hard to follow; which was made more noticeable when Aaron and Nick exchanged a glance.

"What do you mean you saw four, Zak? Four apparitions?" The latter asked. The bleeding man shook his aching head.

"No… Four…" Before he could finish his sentence, he drifted once more to the world of unconsciousness. Aaron gently shook his friend.

"Wake up, man!" He quietly urged. But there was no movement from the injured investigator. "What could have done this? It has never happened before… And Zak always provokes way worse than he did this time."

Then, things came to a new perspective for the two seasoned paranormal investigators. They realized that what they were dealing with was no ghost; it was an intruder. And how exactly did they figure that out?

Leonardo's cell phone began to ring. He had mistakenly forgotten to turn the ringer off; it was still on from when the brothers had previously believed they were the only ones residing in the abandoned building. He hurriedly shut the device off; but it was much too late.

"Who the hell is in here?!" Nick stood, looking ready to kill. "I thought security cleared out the building, Aaron!"

"I thought so too!" He exclaimed. "Come out or not, we're calling the police." The bald man took out his cellular device, turning it on, when it was knocked violently from his hand by an unseen force. His eyes were wide. "I… I don't know who you guys think you are, but…" Then, he could barely make out four figures in front of him. Nick's facial expression clearly showed that he saw it too. "What…What are they?" His friend could only shake his head in disbelief. They weren't human. That was all he could tell.

"We mean no harm." Leonardo's voice boomed, making him sound frightening; it caused him to seem the exact opposite of what he was trying to assure them.

"Like hell you don't! Now show yourselves!" Aaron yelled, making himself seem out of character and threatening. The brothers looked to one another; they didn't know what to do. They were already seen. They needed to just find it in themselves to trust these men with their risky secret. Then, the leader of the clan did something the brothers never expected.

He stepped forward, with his hands out at his sides, palms facing upward in a non-threatening gesture. Both Aaron and Nick's eyes widened at the sight of the creature; Zak had always been the one to believe in aliens. But they didn't even know if the turtle creature was an alien. Then, three more stepped forward. Each of the four creatures wore a different colored mask.

"We do not mean harm. We mean it." Leonardo spoke in his calm and collected manner, showing his position as the leader. Nick glanced down to his unconscious friend.

"Then why did you hurt Zak?!" He shouted, still on the offensive. The eldest turtle kept a level head.

"It was a misunderstanding. We didn't know any one was in the building, and we had thought he was here to hurt us." He explained. Then, making sure that his hands were in view the entire time, he pulled out his cell phone. "We have a friend, who just contacted me, who can fix your friend up as good as new. You just need to trust us." The two humans looked to each other, and then to their fallen friend.

"Who is going to help him?" Nick was still wary of the mysterious creatures.

"Our friend; their name is T.J., and they can fix him up to the point where we can pretend that this," He gestured to themselves and Zak. "Never happened. You in?"

Aaron and Nick could only reluctantly agree.
