Rewind

Snapping awake on the Hogwarts express, Harry jumped to his feet, frantically patting himself down before the realisation he wasn't on fire sunk in.

'Okay,' he told himself as he, dropped heavily back into his seat, 'so apparently, I can't out fly a dragon.'

He was starting to lose track of how many times he'd woken up on the train after dying. At least he reacted better this time.

The first time it had happened had been bad. One moment, he was on his knees, Lord Voldemort standing over him with a wand in hand and a smile on his face. The next, he was back on the train.

… He hadn't taken it well.

Assuming was some kinda spell robotics, he'd started firing spells and hexes before throwing himself from the still moving train.

After a second death, he'd realised that just maybe it was true, he'd really gone back in time. Maybe … He could fix everything?

Then Ron had walked into the compartment.

"Harry, mate, there you are." Just like that.

At least Harry no longer felt like punching him any more.

"I've been looking all over this bloody train for you," Ron complained as he came into the compartment and dropped into the seat opposite.

The first time back, he'd decked Ron the moment he'd seen him.

"Sorry Ron, I … fell asleep." Harry said, trying to sound sincere.

It wasn't fair to blame Ron for leaving him. They had been almost constantly at each other's throats when they found out the Weasleys had needed Ron's help. Between that and the damn necklace, Ron had left and never came back.

A month later, Harry had his final meeting with Voldemort.

Of course, it would have been easier to get along with Ron again if he didn't know what was coming. The Triwizard tournament and with it, Ron's jealousy.

Maybe he could do something about it, find Ron something he could feel better about before things went wrong? Of course, that left him with only two months to figure out how.

And while I'm at it, I could invent a new type of music, he thought bitterly. Maybe he could point Ron in Lavenders direction?

The first few loops, he'd tried going to Dumbledore and telling him everything. The tournament, the fake moody, Voldemort's resurrection, the war...

The first time ended with him in the hospital wing, doped to the eyeballs on calming draughts and the fake moody exposed.

Then someone had dropped a portkey on him, sending him to graveyard. A month later, the restored voldemort killed him.

That kinda set the tone for the next dozen or so loops.

No matter what he did or said, if he exposed Voldemort's plan, he would simply end up getting grabbed by someone in the night or while walking through the corridors and everything would just end up repeating.

Harry wasn't stupid, his unknown assailant had to be another student, the list started at D and ended at Malfoy. Once -in what he would later admit was a fit of insanity- he'd hit the boy with a blasting curse to the face.

While satisfying, the resulting trial -followed by another kidnapping- had not been fun.

Writing off telling Dumbledore as a bad job, he turned his focus to the Triwizard tournament.

Unless he wanted to expose Moody, there was no way for him to avoid being entered. So instead, he considered it a challenge, a chance to make less of a fool of himself. And just maybe, he could do something, anything, to stop Voldemort's resurrection at the end of year.

Then he went up against the Dragon.

It seemed he was fated to fight the damn Horntail. Three times now He'd gone up against it and every time he'd ended up on the trail. It seemed his victory the first time was more luck than anything else.

"You alright mate?" Ron asked, "You've been a bit quiet… Why don't we go find the twins, I'm sure there up to something fun."

"No that's alright, I think i'm coming down with something," it was surprisingly how easily liying came to him these days.

At Ron's worried look, he decided to change tactics.

"Ron… Where's your trunk?"

"Oh, I left it with my… brothers,"

"Right… So you left your trunk alone… with your brothers… "

The slow dawning of horror on Ron's face was a thing of beauty and Harry swore he'd make it up to his friend later.

"Oh bloody hell!" Ron cursed, jumping up and bolting from the carriage

Laughing quietly at his friend -and Ron was his friend, disagreements notwithstanding- Harry went back to staring out the window. Above, the sky was rapidly darkening with the oncoming rain.

He didn't know why he seemed to be looping through time, but he wasn't going to waste the chance that had been given to him. Maybe this time he could actually save people.

… As soon as he worked out how to get past that damn dragon.

So, yeah, a time loop fic. Fair warning, if I continue it the fic WILL be H/HR. I can at least promise no Ron bashing and a no mass mind rape.
(I consider Partialy kissed hero an example in what NOT to do.)

Edit: sorry for spelling and grammer, but like I said, I wrote this in one sitting, on my phone while traveling to london.
