Sorry for the delay in posting this chapter. RL has gotten in the way of my writing as of late, but I am still working on this story. It's nearly complete. I promise to get more posted as soon as I possibly can. Thanks to everyone that's still reading this. I appreciate all the comments and feedback. Speaking of feedback, someone asked whether Snape and Severus are the same person, and the answer is yes. I just assumed most everyone knew that Professor Snape's first name was Severus and so I use both names interchangeably.My apologiesto thereader that was confused by that. And now...on to the story.

In his snake form Jack slithered through the water watching as the champions began to dive lower into the lake, each searching for that which had been taken from them. He knew he couldn't hold the animal form for very long so he quickly transfigured himself back, then did a bubble head charm so that he could remain underwater.

Carefully, he swam through the dark waters, staying hidden among the algae and plant-life on the lake's bottom. He managed to find Harry several minutes later, and to his surprise the boy was very close to his target. The merpeople began to approach Harry and Jack was quick to get out of sight.

He could see Harry struggle with the mermen trying to keep him from taking Ron and Hermione both. A moment later Cedric and Viktor arrived, each taking their respective treasure back to the surface. Jack watched in amazement as Harry continued to wait for Fleur to arrive. When it was obvious that the young witch wasn't going to show, the young man tried once more to take both Ron and Fleur's sister with him, but the mermen were quick to stop him.

Giving in Harry took off with Ron in his arms. Jack could see the effects of the gillyweed beginning to wear off as the younger wizard began to clutch his throat as he approached the surface. For a moment Jack hesitated, but quickly swam towards the flailing boy, giving him a push the few more feet he needed to break the surface and get the air he desperately needed.

As his head came out of the water, Harry gasped, his fingers still clutching Ron's arm tightly. He looked back into the water and could see Jack waving up at him before hurriedly swimming away before his presence was noticed. Strong hands pulled Ron and Harry from the water, but Harry kept his eyes fixed on the water.

> > > >

Jack didn't emerge from the water until the crowd had dispersed, and the area around the lake had been cleared. Trying to keep out of sight, he crawled out of the opposite end of the lake. To his great surprise he found himself face-to-face with an irate looking Sirius Black.

"What on Earth are you doing here?" Black asked as he shook his head at Jack.

"I was trying to help Harry."

"You do realize everyone is looking for you, right?"

Rolling his eyes Jack nodded. "I could say the same about you."

"Tell me what's going on." Sirius reached a hand out to help Jack to his feet.

Once he was on his feet the older wizard shrugged his shoulders as he pulled his wand out and pointed it at himself as he whispered an incantation to dry his clothes.

"What are you talking about, Siri?"

"Don't toy with me, Jack. I saw you with Moody before the second task began."

Feigning a surprised look O'Neill shook his head. "With Moody?"

"I'd recognize your pathetic snake transfiguration any day."

Busted Jack smiled weakly. "It's complicated."

Sirius took a step towards Jack frustration and irritation clear in his eyes. "What does Alastor Moody have to do with Harry and this bloody ruse they're calling a tournament?"

Before Jack could respond Sirius stilled, hearing someone coming closer. Jack motioned for him to hide and the wizard transformed into his dog form, quickly running behind a nearby tree.

"There you are. Let's get outta here before anyone sees ya." Moody snarled as he waved an arm at Jack.

Quickly Jack moved towards the peg-legged wizard, casting a glance back at the tree where Sirius was hiding.

> > > >

"You said you'd explain things when the second task was finished." Daniel crossed his arms over his chest as he waited for Severus to respond.

The dark-haired wizard sighed heavily as he fumbled with the hem of his robe. "There are things going on here that are beyond our control."

"What the heck does that mean?" Daniel was straining to keep his voice calm, but he knew he was ready to lose it completely.

"What Professor Snape means to say is that there is far more to all of this than you were led to believe."

All heads in the room turned towards the doorway of Snape's office where Dumbledore was standing. The grey-bearded wizard stepped inside, carefully closing the door behind him.

"What's that supposed to mean?" The archeologist looked from Snape to Dumbledore and back, his eyes demanded an answer.

Dumbledore turned his gaze to Teal'c, who was standing just to his left. "I believe if Teal'c would be kind enough to tell us of the dreams he has had of late, things will make more sense to you."

"What do his dreams have to do with anything?" Carter threw her arms in the air, obviously flustered at the whole situation.

The headmaster pushed his spectacles further up the bridge of his nose as he smiled softly at the members of SG-1. "When we asked you to return it was because of your friend's dreams. I do believe they are of great importance to what is going on at the moment."

"But what exactly IS going on, Dumbledore?" Daniel asked as he took a step towards Albus.

"All in good time, Dr. Jackson. First, we must hear from Teal'c."

Then all eyes were fixed on the Jaffa as he nodded in their direction before beginning to recount the strange dreams he'd had of O'Neill.

Almost an hour later Teal'c had finished telling the group about the nightmare that had taken place in the cemetery, and the strange people he'd seen in the dream. As the Jaffa spoke Dumbledore was curiously stroking his beard as he sat quietly on the chair beside Daniel.

"How is this going to help us find the Colonel?" Sam finally asked as she brought her hands to her hips once her teammate had finished.

Dumbledore stood as he responded. "Major Carter, I believe that Jack gave this vision to Teal'c in order to warn us of what was to come."

"What vision? This was just a dream….wasn't it?" She shook her head in disbelief.

Snape got his feet before Albus could answer, diverting everyone's attention. "Dumbledore's right. This is the only explanation. Jack was always a powerful seer. It wouldn't surprise me if found a way to project his visions like this. If anyone could do this, it would be him."

"You'll have to excuse us if this all seems a little bizarre." Daniel spoke up as he moved his chair closer to Carter who was already taking deep breaths trying to grasp what was being said.

"Why would O'Neill wish to do this?" Teal'c asked as he turned towards Dumbledore.

"The things you have seen in your dream are things that may yet come to pass. I believe he needs your help to ensure that they do not."

Daniel glared at Albus, not sure what to say. "How are we supposed to do that?"

Dumbledore brought his hand up to his chin, pursing his lips for a moment as he considered what he was about to say. "First, we must speak with Corrigan."

"We don't know where he is!" This time Daniel was shouting as he leapt from his seat.

"Actually, if I'm not mistaken he's somewhere on the grounds."

Everyone was stunned by the headmaster's statement. Daniel face was red in a mix of anger and frustration, Teal'c arched his eyebrow nearly off his face, and Carter blinked in confusion as Dumbledore's words sank in. Severus was the first to find his voice once the momentary shock wore off.

"Headmaster, how is that possible?"

"With all the excitement of late, I hadn't had a chance to mention it, but Jack came to my aid while I was with the Centaurs. We parted ways just before we reached the school grounds, and I'm certain he's still here."

> > > >

Moody closed the door to his quarters and with a growl tossed a slithering green-eyed snake on the floor. A second later the snake transformed, revealing a haggard looking Jack O'Neill.

"I told you Potter would be just fine!" Moody bellowed as he turned away from Jack.

"He almost wasn't. He nearly drowned out there today. The plan is to keep him alive until the end of the tournament, then the Dark Lord gets the satisfaction of killing him."

"Don't talk to me about the plan. I know what I'm supposed to be doing!" Moody snarled.

"Do you? It looks to me like you're just making things up as you go along." In a flash Jack found a wand pointed square in his face, the other wizard surprising him with his speed.

"I'll never understand why Master sees fit to keep you around. Without those bloody visions of yours you'd be utterly useless, Corrigan."

Smirking Jack took a step back, carefully pushing the offending wand way. "My Sight is the only reason he bothered giving you a chance to serve him."

"Rubbish!"

"Not really. He was set to kill you along with your pathetic excuse for a father when I told him you might be an asset." Rolling his eyes Jack crossed his arms over his chest. "Too bad I was wrong. You're just a waste of magic like your father."

He turned his back on the other wizard for a second. The floor creaked softly as Moody lunged for Jack. He turned around just in time to get his wand and whisper a silent curse that sent a white spark flying towards Moody. The peg-legged wizard dropped his wand, instantly clutching his throat as he tumbled to the floor. A moment later Jack approached him, picking up the dropped wand. He held it in his left hand while his own wand was grasped tightly in his right.

"I should let you die." The words left Jack's lips and the writhing figure on the floor could see that there was no remorse in the wizard's voice.

"P-please." He managed to rasp as he flailed about on the floor, his body slowly beginning to transform back into that of Barty Crouch Jr.

"Only because Master wants you to complete your task." Jack waved his wand and a blue spark erupted from it. Crouch released his throat, gasping as his air flow returned to normal. Once Crouch managed to sit up straight, Jack moved closer, forcibly digging his wand into Barty's throat. "This is the last warning I'll give. I may not be the strongest wizard, but I can more than handle a foolish child like you. Insult me again, and I won't hesitate to finish what I started tonight." Crouch gulped in a breath, the fear evident in his eyes. "Now, take your damned potion before someone sees you."

Jack stepped away, allowing Crouch to reach in his pocket for the polyjuice potion he kept there and waited for the wizard to take it and change back into Mad-Eye Moody before speaking again.

"We don't have much time. It'll take both of us to do what the Dark Lord wants done."

Crouch nodded quietly as he waited for Jack to explain the next phase of Voldemort's plan.
