Chapter 3: The Boy who lived/The Leaky Cauldron
Leo's P.O.V

Leo couldn't wrap his head around the whole 'time travel is possible' thing, and it was giving him a really bad headache. He was thinking that if it was possible, he could probably build a time traveling machine and stop Gaia from waking, and his mother from dying, so he was really freaked out when a rough cough came from behind him. He turned around to find a dark skinned, huge lump of a man with shoulders that were at different heights and a huge, bulging, misshapen head and a leg in a steel brace, with a wild brown beard that sparked fire from time to time. He was wearing a jumpsuit smeared with grime and oil with the name Hephaestus embroidered over the chest pocket. He was smiling awkwardly at him. He smiled too and said, "Hey dad, how've you been?"

"I've been good Leo, it's you I'm worried about," he exclaimed in a husky voice that reminded Leo of a famous actor he saw in a movie, with his mum a long time ago.

"What do you mean?" he replied.

"I know how tempting it will be to save your mother, once you're back in the past but you'll have to resist."

"Why should I? Why can't I have another chance at a proper childhood? Why can't I be happy like everyone else?"

Hephaestus smiled sympathetically at his young son and said, "I know what that feels like. I know what it is like to be unwanted by all the people you know. I even know what it feels like to be thrown off a cliff by my own mother for being hideous. I guess that is a curse all my children have to bear, and for that, I am truly sorry."

"Alright, I accept your apology, but what does that have to do with me bringing back mum?" he asked.

"You see, Leo, if your mother was alive you would not have ended up at the wilderness school with Jason and Piper, and you would not have gone on the quest with them, and they would have been doomed to fail if you hadn't been there to help them. They would have died back then and the Great Prophecy would never have been fulfilled, and the giants would have won the war, thus ending all life as we know it, and effectively killing Esperanza again."

At that, Leo was dumbstruck; he hadn't thought of it that way.

After he'd regained the power to speak, he said, "So, what you're saying is if I save mum from dying in that fire, she would die again, and this time probably by some monster working for the giants?"

Hephaestus only nodded his head in reply.

After waiting a moment for Leo to process what he had just learned, he said, "That's why I want you to swear on the river Styx, that you will not do anything of that kind."

Leo hesitated for a moment; he wanted his mum back very badly, but on the other hand, he didn't want the giants and Gaia to win. Leo was many things, but he was definitely not that selfish, so he said in a sad voice, "I swear on the River Styx that I won't stop myself from killing my own mother." Saying it that way, he looked like the villain in this story, thought Hephaestus to himself sadly.

Then he said, "I know it is going to be hard but it is something you have to do."

Leo sighed and said, "I have to go pack."

His dad nodded and Leo started to walk away. That was a lot to take-in, in one night. When he got close to Cabin 9, he put on a mischievous smile to mask his sadness, and continued like always. His bag was pretty light; just an extra pair of jeans, a camp T-shirt and tool belt of awsomeness. After he finished packing, which didn't take long, he went to Cabin 1 to find Jason. He didn't find him there, so he went to the Aphrodite cabin; he was probably helping Piper pack.

When he got there he found them just walking out of the Aphrodite cabin holding hands, and when he caught up with them, he started teasing Jason by saying Percy's powers were cooler than his, which always pissed him off. But he only did it this time, because he wanted to take his mind of his talk with his dad, and he didn't want anyone to notice his gloomy mood.

By the time they got to the Big House, everyone else was already there and after a few minutes, Hermes came to pick them up. He looked really awsome and witty like the kind of guy Leo would hang out with; he had a look on his face that said he would pull the prank of your life on you, just to see your reaction.

He then gave them a short version of time travel problems, which Leo tuned out and started fiddling with a length of wire and some coil (don't blame him, blame the ADHD). When he'd finished with them, he had a miniature skeletal bird in his hand, he decided to listen to the conversation again and only heard Hermes saying, "Now touch me" which Leo thought was pretty hilarious.

By the time he had stopped he noticed the room had gone silent, the he saw her, Rachel also the Oracle of the camp, she walked in them started saying the new prophecy.

"A new evil stirs in the dark,

Kingdom of the dead undone by the heir,

Time must rewind to reverse the fall,

Blood of the three to stop it all,

Snakes and lions shall ally,

Both worlds shall merge and end as one,

With the help of the hero lost in time."

Leo was confused, why would they need snakes and lions¿? Who was the hero lost in time¿? His train of thought was broken by a soft cough from Hermes.

"Well…, there you go. Now you have your prophecy. I think you're all set for the trip" said Hermes, he then continued

"Now, come on all of you, touch me"

This time he didn't even have it in him to laugh so he just went ahead and did it.

When they were all touching him they started to spin like crazy and Chiron said something he couldn't quite make out, so he decided to concentrate on trying not to lose all his dinner, but that was the last thing he remembered.

When he woke up, he had a very bad headache, and he felt like he had just eaten one of the 3 day old casseroles one of his foster families used to give him. He then noticed that he was lying on a very comfortable bed, so he decided to get up and take a look around. When got up he almost fell. He felt like his feet were going to give away, so he sat back down and looked around.

To his horror the whole room was all made of wood: a wooden bed, wooden chair, wooden wardrobe and even wooden walls. This was the worst possible place for him to stay except maybe a Justin Beiber concert. He got up again; the dizziness came back, but he fought it and got out of the room as fast as he could.

He found himself in an unfamiliar corridor with many doors. He headed down the corridor, where he found a staircase heading downstairs. He followed it and found himself in a bar, filled with weirdly dressed people; many were wearing pointy hats, that Leo thought made them look comical, then a huge guy walked in he could have been mistaken for a short adult Cyclops or a tall, young one, he was also really, really wide and when he said wide he meant three men wide. Right behind him was a boy who looked like he was ten or eleven years old with jet black hair and emerald green eyes.

He was wearing clothes that were meant for a kid who was at least twice his size, and he looked like he was trying to melt into the shadows. Then the boy scratched his head, and that was when Leo saw his lighting like scar and he thought: that would look really epic on Jason's forehead he could even make it crackle with real lighting. When they got to the bartender he looked really surprised but look up at the gigantic guy and stuttered out:

"Hagrid is this...?"

"Could it be...?"

"Bless my soul, its Harry Potter, what an honour!"

At his words the whole bar fell silent and stared at the boy, who tried to hide behind Hagrid, which would've been easy if he wasn't caught in the midst of a group of adoring fans in no time. At that, Leo went to talk to the bartender about finding him a room that was less flammable, but on his way he found Nico sitting at a table alone, and staring intently at a shrivelled up looking man, who was walking towards Harry and Hagrid the mini-giant. The guy was apparently starting to bald and wore a turban to cover his head or something, but Leo didn't like the way Nico was staring at it. After the man talked to the pair, he left them and they walked to the back door of the bar. Leo talked to Nico and they decided to follow them; better start protecting him now rather than later.

With that cosy thought in their minds, they followed them out of the bar which was called The Leaky Cauldron, according to Nico.
