The 3 of them snuck into the Hogwarts tower.

"Stay vigilant." Said Twilight. Twilight really wanted to admire the mystical ceilings and long hallways, but they didn't have time. Hermione had her Time turner clutched tightly in her hand. They found a small empty space near the library.

"Ok, quickly." Said Hermione. She put the necklace around the three of them.

"How far are we going back?" Asked Dash.

"A few hours, so we can save Harry." Said Hermione. The world looked weird around the 3 of them. There were people all around them walking. Finally they stopped. There was bitter silence.

"Come on." Said Hermione. The three of them left the building sneakily, dodging as many people as they could. They had a few close calls, but Dash managed to knock those people out. They did have to be very quiet. Soon they saw Past Harry and Hermione sneaking around, so they followed them. After following them for a while, they finally stopped outside the trapdoor and waited there for a while.

'What now?" Whispered Rainbow Dash, who was insanely bored. They were hiding a few meters behind Harry and Hermione.

"We ta-" Twilight began, when suddenly Past Dash zoomed into Harry and pushed him into the ground.

"Follow them!" Whispered Twilight excitedly. The 3 followed Dash and Harry secretly. When they finally stopped, they saw Dash apologizing and introducing herself to Harry.

"Come on, this way." Urged Twilight, and the three of them rushed off into the woods, towards the lake where Harry died. They had to be careful not to bump into their past selves. Hermione was showing Twilight which way to go. They carried on for a few minutes, exploring the eerie and dark forest.

"Why are we following past me and Harry when and why did we go into Hogwarts when we could of done the time travelling so much closer!" Said Rainbow Dash impatiently. Twilight sighed.

"We had to know where we you and Harry were so we had a better plan." Said Twilight. Dash nodded quickly.

"We are running out of time, Hermione. Where's the lake?" Asked Twilight nervously.

"I.. I think it's close." Said Hermione. She was sweaty and her hands were shaking.

"Come on, Hermione." Urshed Dash, a little panicky. Twilight's ears pricked up. She could hear screaming. "Listen guys." Said Twilight. Dash listened to the sound them. Some kind of yelling in agony.

"This way!" Exclaimed Hermione, her bushy brown hair swaying. Dash and Twilight flew through the grabbing trees scratching at their coat. It doesn't matter. There are more important things to worry about, Thought Rainbow Dash, her blue wings flapping quickly. They arrived at a crystal ice river, with spooky hooded creaches floating over Harry and Sirius Black. They were screaming for agony. Their souls white ghostly souls coming out of their mouths.

"No!" Cried Hermione. She pulled out her wand.

"Expecto Patronum!" She called, but nothing but a small spark came out. "No..No.." She mummered.

Twilight didn't know what to do. Maybe she should try the Patronus charm herself. Her horn glowed a vibrant pink and in her head she yelled EXPECTO PATRONUM! A small glow came out her horn, but it wasn't enough.

"No!" Twilight sobbed. She walked over to Harry and Sirius and stared at the floating souls. It was too late.

Harry would never live again. Hermione came down and sat next to her. Dash flew over to. The dementors flew overhead and tried to stoop down, but Twilight had a forcefield on so they couldn't come near her. Dash saw Harry's wand on the ground.

"Don't bother with it Dash. It's not going to do anything. You don't even know what a wand is." Said Twilight Sulkily. Dash picked it up, staring at it's wooden interior. She thought of herself and Harry before. She decided to try with it. She may have never used one before, but it couldn't hurt to try. She raised it up.

"No. Rainbow it's not going to work. It's not your wand." Said Twilight. "You have no idea how to use it."

"Listen Twilight, this is all my fault that Harry is dead, so I'm going to make things right. If it doesn't work, then at least I tried." Said Rainbow Dash. She flew out of the force field so the dementors could get a good look at her.

"EXPECTO PATRONUM!" Yelled Dash as loud as she could. Nothing happened. The dementors were coming. Dash tried again, but still nothing. She dodged the dementors and zoomed down to Twilight.

"One more time." Said Dash. "EXPECTO PATRONUM!" Nothing happened. Dash sighed and Twilight let her into the force field. Not before she dropped Harry's wand outside. "No!" Cried Dash, and tried to go after it.

"Don't. It's useless now." Said Twilight. The dementors were all around The forcefield now.

"Accio Wand." Said Hermione. Harry's wand came to them.

"Thanks Hermione." Said Rainbow Dash, patting her rainbow mane. She looked at Harry's wand and put it in Harry's hand.

"Expecto Patronum." Said Dash sadly. Suddenly a bright light echoed from the wand, spreading out. Twilight removed the forcefield. A bright white stag appeared, spreading a brilliant white beam everywhere. The dementors were shooed away. Harry (and Sirius) were saved!

'We'll leave you to it, Hermione." Said Twilight, and she and Dash left off to find the other Harry, which wasn't too difficult. They found a secret spot in the bushes where they watched past Hermione, Dash and Twilight discuss their plan then leave to the Hogwarts tower. As soon as the coast was clear, Dash went up to Harry, who was just waking up.

"Rainbow Dash?" He said Dazily.

"That's me." Said the blue pegasus. Harry looked over at Twilight.

"Who are you?" He asked.

"I'm Twilight Sparkle." Said the alicorn, helping Harry to his feet.

"Whoa. A winged purple talking unicorn." Said Harry, astonished. Twilight nodded.

"Sirius!" Said Harry, astonished. But Twilight just simply smiled.

"I think somebody else will take care of that. As for you, time for you to get out of here." Said Twilight, teleporting him back to the hospital room where Ron and Hermione were.

"But Twilight, how are we going to get back?" Asked Rainbow Dash.

"We'll find a way, Rainbow. We'll find a way."
