The weeks leading up to the second task were some of the most stressful of Harry's life. His control over the Bubble Head Charm was coming along quite nicely. The bubble no longer popped when he touched it, but he still felt it could be stronger than what it could be. That was where his plasmids came in handy.

If he felt his bubble was becoming too flimsy he would solidify it with Winter Blast to reinforce the water surrounding his face. Of course that added the problem that he would be left with limited air, so he had to be careful how cold he made the bubble. It wouldn't do any good for it to go and pop on him during the task.

"I told you that you could do it," Rose said as he climbed out of the large tub.

"Thanks," he said. "It's no Big Sister suit, but it'll have to do."

"That suit isn't as wonderful as you would think," Rose said. "It feels like I'm trapped in a fish bowl."

"Better a bowl than a bubble," Harry commented in a joking manner.

Finally the day of the second task arrived. Harry dressed in lightweight yet warm clothing, while Rose wore her suit. She had made a few modifications in that she removed the metal boots so she would be able to move better while underwater.

A knock sounded from outside their room and when they opened their door/painting they were met with Professor McGonagall. "Good afternoon," she greeted them both. "I take it you are ready for the second task?"

Harry and Rose both gave a nod to the Hogwarts professor.

"Is that what you will be wearing Miss. Potter?" McGonagall asked as she eyed Rose's strange outfit.

"It is professor," Rose answered. "It's not a problem is it?"

"No," McGonagall told her. "A bit unorthodox but not a problem. Come, the champions are congregating near the Black Lake."

McGonagall led the two to the shore of the Black Lake where the other three champions were assembled. Cedric was stretching his arms to ensure they were in prime swimming condition. Krum stared out at the lake in his usual stoic pose, and fleur seemed less composed than usual. Her brow was furrowed and she kept gazing at the crowd of students that were gathering in the stands behind them, it was as if she was looking for someone in particular.

"Welcome! Welcome!"Bagman said as he came over to where the champions were assembled. Harry saw the rest of the judges walking over to where they now stood. The Lutece twins being among them as well as the one redheaded man from the Yule Ball in place of Crouch.

"I take it you've all solved the mystery of the golden egg?" Bagman asked the five. "Excellent! So you all know the rules of this task yes? Might as well inform the crowd then." He put his wand to his throat and his voice became amplified.

"Good evening ladies and gentlemen! Welcome to the second task!" a large cheer erupted from the assembled crowd. "Last night something was stolen from each champion and now resides on the bottom of the Black Lake. They have one hour to find what was stolen and return to the surface. Champions are you ready?"

Rose snapped her helmet into place, a green glow emanating from the port hole signaled she was ready. Harry meanwhile took a few deep breaths to calm his nerves.

"On you mark! Get set! Swim! Bagman fired a spell into the sir that sounded like a cannon. Harry saw Rose take off into the shallows much faster than any of the others and he began to trudge in after her.

The cold he felt from the lake pierce his legs but he kept on wading through the water to catch up to Rose. The water soon came up to his neck and he muttered the incantation best he could before plunging his head under.

His nerves seemed to shut down momentarily but he felt a familiar feeling wrap around the lower half of his face and he found that he was able to breath. The spell seemed to do a little more than that as the water suddenly didn't feel as cold as when he first submerged.

He saw Rose ahead of him twist her body so she was facing him. She jerked her head farther out and motioned him to follow after her. Harry instantly obliged and swam towards her into the deeper waters.

The Black Lake was eerie. Plain and simple.

But Harry was thankful it was nowhere as eerie as Rapture had been. In the underwater city you were trapped both inside and out. Here the lake was quite shallow as opposed to the ocean floor and they would be able to swim to the top. And plus Harry could see the sun shining down from their current depth, something he was never able to do while in Rapture. That thought alone gave him some sort of comfort.

The two of them kept swimming deeper into the lake where they were soon met with the sight of a large seaweed garden of sorts. The two of them were about to swim over it until they heard a singing of sorts coming from within. Singing that sounded an awful lot like the one from their eggs.

Rose pointed into the seaweed and swam into the tall stalks followed closely by Harry. The further they swam into the stalks the thicker they became so Rose pointed up signaling that they should try and stick to the higher parts of the plants. Harry nodded and began to swim up, but was stopped when he felt something grab hold of his leg.

He thought at first it might have been one of the stalks but when he looked down he was met with the sight of an ugly little horned creature with sharp teeth and octopus tentacles on its lower body.

Harry kicked his leg around in a wild attempt to shake the creature off of him, but to no avail. If anything it seemed to tighten its grip on him as it then proceeded to sink its teeth into his flesh.

He let out a scram of pain from behind his bubble which began to shake almost like it was going to burst.

Rose dived straight for the creature and impaled the creature on her needle killing it. As Rose shook the body from the needle Harry used this time to briefly freeze his bubble as to stabilize it.

Looking at his injured leg Rose pointed to it concerned. Harry brushed it off and held up the OK sign letting her know he was ready to move forward.

As they swam through the last of the seaweed they spotted a few more of those creatures, but knowing what to expect Harry froze them solid with his plasmid and watched as they floated up to the surface.

After clearing the seaweed they were met with the sight of some kind of underwater structure, almost like an ancient Roman or Greek building. Almost like…

No.

This wasn't like Rapture. Harry shook his head to clear his thoughts. This is probably just part of the task. This is just a coincidence. Never mind the fact that Rapture had many locations named after Greek Gods like Apollo Square, Artemis Suites, Hephaestus Core, Point Prometheus.

And never mind the fact that he just saw a giant mass of tentacles swim by that belonged to a Giant Squid. Just like the one that used to swim around Rapture.

This… this was too much. Too much like that hellish place. He couldn't…

Rose swam over to him and grabbed him by his shoulders. She snapped her fingers in front of him creating small bubbles as she did so in an attempt to bring him back to reality.

Harry shook his head once again to rid himself of any doubt as he focused on the glowing green porthole that belonged to Rose's helmet. What was he doing?

He didn't spend the last few weeks working on the Bubble Head Charm only to give up and have a mental breakdown now. Just keep moving, find what was stolen and get to the surface.

Harry gave her the thumbs up to let her know he was fine, and together they made for the underwater structure.

Mermaids were not what Harry thought they would be. He thought they were supposed to be youthful and beautiful, not tough and angry. The men had grizzled beards, while the women had sharp angular features and hard eyes that seemed to judge the two of them as they swam through their city. Yet despite the hard glares no mermaid made any move to stop or attack them.

They kept swimming until they reached what Harry could only assume was the village square, and that's when he saw them.

Luna, Neville, Hermione, the girl Cedric brought to the ball, and a young girl who looked very much like Fleur. They were floating there their ankles tied by rope and anchored to the stone floor.

This is what was stolen?! People. The people they had brought to the ball. Was that what the Yule Ball had been about? Find out who you would bring and then kidnap them? Everyone down here was the date of a champion, save for the girl, but then again Fleur hadn't seemed all too interested in her date. This must be a relative.

By the look of things they were the only ones to arrive so far, and they only had an hour before the task ended. That means if the others didn't get here soon…

Harry and Rose swam over to Neville and Luna. Rose used her harpoon and needle to cut the ropes binding them. She pointed up towards the surface and started kicking upwards when Harry grabbed a hold her leg.

She tilted her helmeted head to the side. What? She seemed to convey.

Harry pointed to the other people still bound. What about them?

Rose pointed to both of their hostages and then back to the surface. We got what we have to. The others will do the same.

Harry shook his head. You don't know that.

Rose nodded. I do. She pointed to the surface again. Let's go.

Harry shook his head again. He pointed to her and pointed to the surface and then to himself and back to the other hostages. His message was clear enough. She could go if she wanted, he would stay here.

He swore he could actually hear Rose sigh from within her helmet. Rose pointed to the both of them and then the surface. She pointed at herself and back to the lake floor. She tapped her oxygen tank and held up the OK sign.

The both of them would go up together and then Rose would come back down to ensure the other hostages made it as well.

Harry grabbed Luna and Rose grabbed Neville and the two of them kicked off towards the surface which seemed a lot closer than it actually was. The both of them kicked as hard as their legs would allow, Rose especially since her suit did weigh her down a bit. And there it was the surface.

Harry's head broke the surface of the water and he felt the bubble disappear as he caught sight of Rose diving back down into the deep. Both Luna and Neville opened their eyes as their heads emerged from the water.

Neville looked around wildly like a scared deer while Luna didn't seem too affected. "H-harry?" Neville asked as Harry began dragging the two of them towards the shore where the crowd was awaiting. "W-what happened?"

"You were kidnapped," Harry told him as he let go once he was sure Neville could stay afloat on his own. "We had to go to the bottom of the lake to rescue you."

"Kidnapped?" Luna asked as she swam close by. "Strange. I had a dream I was kidnapped, and now I'm here."

Once they were at the shore Harry helped both hostages out of the water. Madam Pomfrey rushed over to them with warm blankets and began to wrap the three of them up in them.

"First dragons now freezing water," the nurse mumbled to herself. "What's next?" the nurse led them over to a bench that had been set up where the only other occupant was Fleur.

Fleur?

Why was she here and not trying to get her hostage?

The moment Fleur saw Harry she rushed over to him. "Did you see 'er? My sister? Eez she down there?" So that girl was her sister.

"Y-yeah," Harry answered. "I saw her." His response only seemed to make Fleur more frantic.

"I must go back een."

"No you will not!" Madam Pomfrey told her. "Your wounds still need time to heal. Until then you are in no fit condition to do anything."

Tears began to pour from the girl's eyes. "Fleur," Harry said to the other champion. "My sister is down there. She's waiting for the other champions to get their hostages. When she realizes you won't show up I know she'll bring your sister up."

"But she is not 'er's to save," Fleur pointed out.

"Yeah," Harry admitted. "But it's still not right to leave her there." His thoughts drifted momentarily back to Rapture. "Believe me she will."

The next to emerge from the water was Cedric and the girl he brought to the ball. A large cheer erupted from the Hogwarts students. Following Cedric by a few minutes was Krum who had a sharks head, as well as his hostage, Hermione.

The clock ticked by and by and Rose had not yet emerged from the lake. It had been well over an hour since they first entered the lake and Harry didn't want to think about what would happen to either of them if they were under there any longer.

Bubbles began to coat the surface of the lake and an all too familiar helmeted head broke the surface along with the young girl as well as several mermaids following close behind. Both Fleur and Dumbledore ran to greet the assembly as they made their way to the shore.

Fleur took hold of her sister and surprisingly gave Rose a hug of gratitude. Harry couldn't see her face through the port hole but he knew she must have been caught off guard. Dumbledore meanwhile seemed to be exchanging words with one of the mermaids.

Rose made her way over to the bench where Harry and the others sat and took off her helmet. "How did you know Fleur wasn't coming?" Harry asked.

"I didn't," Rose told him. "I just got tired of waiting." She looked over Harry's shoulder and waved. "Looks like someone came to visit."

Harry turned to where she was waving and saw that the stray dog, Padfoot, was sitting idly by the stands of students. The dog raised his one paw and seemed to almost be waving at them, as impossible as it seemed.

"Attention!" Dumbledore's magically amplified voice called out. "The winner is: Mr. Potter! For his exceptional use of the Bubble Head Charm, as well as assisting in the rescue of two hostages." The crowd cheered loudly at this, But Harry saw that Malfoy and his two goons did not.

"In second place is Mr. Diggory who also showed exceptional usage of the Bubble Head Charm and tied with him is Miss. Potter for not only saving her hostage but young Miss. Delacour as well."

Fleur and her sister both hugged Rose who looked very uncomfortable with all the attention.

"In third place is Mr. Krum, and forth place, Miss. Delacour."

"Congratulations," Cedric said to both Harry and Rose as he offered them both a hand. "I know I don't know either of you that well, but you did amazing today."

Harry and Rose both shook his hand and congratulated him as well. Even Krum seemed to give the two of them a nod of approval.

"That was quite the performance," the voice of Robert Lutece said as he and his sister approached the two Potter's.

"Yes," Rosalind agreed. "But unnecessary."

"What do you mean?" Harry asked as confused as always when it came to these two.

"She means that none of the hostages were in any real danger," Robert clarified.

"But the riddle-,"

"Was just that, a riddle."

"Simply motivation to ensure you finished on time."

"Does that answer your question?"

"I actually have a question for the two of you," Rose told them.

"And what might that be?" Rosalind asked.

"When me and Harry-,"

"Harry and I," Robert corrected.

Rose sighed. "When Harry and I first got here we had the same dream and his nose started bleeding. What do you know about that?"

"What makes you think we know anything about that?" Rosalind asked her.

"Don't you?"

"We can certainly theorize," Robert told her.

"The most logical conclusion would be that you both were receiving memories from another version of yourself. Perhaps an effect of entering this timeline."

"Or a glimpse into another reality," Robert added.

"But what does that mean?" Rose demanded.

"It could mean something," Rosalind began.

"Or it could be nothing," Robert finished.

"Who's to say for sure?" Rosalind asked.

Rose sighed. As usual they were making no sense whatsoever.

Dumbledore could honestly say that he was stumped. A few of his contacts got from the International Association of Wizards got back to him letting him know there were no records of Harry and Rose's supposed school in existence.

Nor was there any proof that an entire school was able to move at will through any known magical means.

He had been hoping that perhaps the supposed Headmaster Comstock would be present during this task, but once again it was the twins, and he knew that any question he asked them would prove futile.

This was not looking good for the Potter's. These are dangerous times with the events at the World Cup, and the sudden disappearance of Barty Crouch. If he didn't have assurance soon that this school was real and protected then he would have to pull strings and place the both of them back with their relatives. It was not an easy choice, but they needed to be kept safe.

But for now all he could do was wait. Wait to hear back from either the committee, or this "Columbia" as well as the third task. He didn't know why, but he felt that after the next task nothing would be the same.
