The next chapter is here because I have this idea now and must finish it! This story was supposed to be cutesy-pie but it turned into a real sci-fi, Doctor Adventure! I hope you like it so far! This is where things get complicated!

Amy Pond was dead. But how could it be possible. Here one moment, gone the next! All this timey-whimey madness made his head and heart throb. She had been erased from time before, in fact, he had been erased from time before, and he could fix this.

"A memory! All I need is a memory!"

"I'm afraid it's not that simple." A mysterious voice echoed through the TARDIS. Impossible. The Doctor turned around slowly and saw a mysterious girl. She was pale, not very tall, but had long blonde hair flowing to her hips. It billowed in some ghostly breeze, but it was impossible for anyone to penetrate the TARDIS. There she was. A ghost like girl in his TARDIS.

It seemed simple enough to ask: "Who are you?"

"A memory."

The Doctor squinted and was puzzled. Where have I seen this girl before? "What do you mean by that?"

"Doctor," She addressed him sternly. "I am the one who removed Amelia Pond from here."

"Why would you do that? Return her NOW!" The Doctor tried to stay calm, but he was falling over the edge.

"Please Doctor, I did not do her harm and I did not come to do you harm. I came here with a wish."

The Doctor was still fuming. "How could a wish be any reason to remove my best friend from the time stream?"

The ghost smiled a frightening smile. "She is not removed from time Doctor, she just simply is dead. She died five years ago—"

"You're lying!"

"Am I?" The ghost took the yearbook and ripped Amy's memorial out. "Written words never lie."

The Doctor still shook and it took all he could not to lash out against the "memory" or whatever it was. "What about River Song? What happened to Rory Williams?"

"Patience Doctor!" Her hand stopped him. "Things will return to normal if you grant my wish?"

"And what sick wish is that?" The Doctor stepped closer to the floating figure. His rage was rising. "You killed my friend."

"A car did."

The Doctor froze. "A what?"

"Amelia Jessica Pond was killed in a car accident as she crossed the street from Leadworth High School on April 13, 2006. The car didn't see her and Amy didn't see the car. Not that she cared, her face was streaked with tears when the police found her. She was crying before she died. It was the night of the prom and Amy was leaving. Probably a drunken student hit her—"

"Why are you still talking?" The Doctor shouted, and the ghost went silent. "Everything I love Amy, River, even her husband Rory because you killed her!"

"I did not—"

"YOU DID!" The Doctor was crying now, unintentionally. He hadn't cried in many years. Foreign tears fell from his eyes onto his stripped shirt. I hate crying, it gives me a headache.

"If I may finish Doctor?" The Doctor nodded still crying, but trying to hide it. No weakness could be shown to an enemy, if this was an enemy or not. "My name is—"

"I know who you are." The Doctor stopped her. "You're Thalia. You're Amy's friend from High School. She told me you died from cancer yet," The Doctor motioned to her and harshly spoke his last words: ", here you are."

"Yes, but do you know what I really am?"

"I haven't figured that out yet."

"I'm an angel—"

"Shut up!" The Doctor stopped Thalia. "You're not an angel. Angels don't truly exist, at least not in this universe, so tell me now." He pulled out his Sonic Screwdriver and Thalia flinched. "—afraid of the sonic hmmm—what you really are!"

"I can't"

"You better if you want to live." The Doctor's thumb rubbed over the Sonic Screwdriver's deploying button.

"What about your Amy?" The Doctor stopped and put the Sonic away. He had to trust this "angel of death" who took his life from him. "That's better. My wish is for the benefit of Amy."

The Doctor scoffed. "How? You killed her!"

"I DID NOT!" Thalia shouted in an ethereal tone. "I loved Amy too!" The Doctor backed away for a moment. This creature, capable of the love the Doctor felt? Impossible, but so it was. The memory paused and spoke her next words harshly: "I come from a race of creatures that thrives by finding moments to manipulate in the time stream." Thalia grazed her hand over the TADIS' many buttons. The Doctor twitched. "I was put on Earth to find a chance to manipulate it and belay my death. We die if we cannot complete our goal." Thalia seemed very emotional when she spoke next." I did not know when I was put on Earth I would find it so very wonderful."

"Can you get on with it? Amy needs me."

Thalia hissed. "This is important Doctor! You said yourself 'Everything is important.'" The Doctor just stood silently. She was here this whole time, she heard everything. How long had she been in the TARDS waiting for her moment? "I met Amelia and she became my best friend. Unfortunately, I forgot about my goal and grew ill. Amelia was there through everything."

The Doctor touched where one of his hearts was through his shirt. "She always is there for anyone she cares for."

"My goal was uncompleted. I died and my remaining spirit returned to my dimension. I was given a second chance by my superiors due to the kindness I showed on Earth. I returned to Earth, broke my friendship off with Amelia and found the rift in time I could enter." Thalia looked proudly as she brushed her hand across the yearbook. "I survived my senior year; in fact I survived a long time. A long life for a creature like myself, but at a cost." She looked fearfully at the man in the blue box. "For sparing my life, time had to take another victim, and a sad girl walked in front of a speeding car and died before graduation. My old best friend died." Thalia looked down and whimpered. Was she truly sad? "That's why I found you."

"What can I do? Why does Amy matter to you?" He paced around the deck he stood on. "You took Amy's life in exchange for yours. Your alive, she's not. Isn't that what you wanted to happen? Isn't that your races goal?"

"Not if it ruins the life I tried to live!" Thalia cried out. The Doctor stepped down from his anger. Thalia seemed genuinely emotional. "I loved Amy! Not only did my goal take her, her sadness took her! And that is why I am here!"

The Doctor looked into Thalia's glowing eyes. Where had I seen that glow before? "I ask once again, what could I possibly do, what is this 'wish'?"

"I wish for Amy to be happy!"

"She was happy until you messed with time and killed her!"

"No!" Thalia stopped him and gripped his sleeve with intensity. Her ghost like hand felt strange on his arm, but he still could feel it. "Go back." The Doctor looked up curiously. "Go back to her senior year when I betrayed her friendship. Make her happy and maybe, just maybe she won't be killed by a car."

"And what about you?" The Doctor shook from her grip. "What kind of trick do you have in mind, huh? What are you going to do to stop me, either you or Amy lives, so who's it gonna be?"

"Amy!" Thalia shouted. The Doctor scoffed, but continued to listen anyway. Thalia seemed to be close to tears or whatever her race did. How can I trust this memory? "Do it, please! Save Amy! I don't want to live if it means being this?" She spun around floating in the air. "I am only half the memory I was!"

"Aha!"

Thalia looked up confused. "Doctor?"

"I know what you are!" He pointed at her. "An Enpousaian!"

Thalia gulped. "Yes."

"Your kind feed off breaks in time because you create most of them. Also, you have the ability to manipulate the memories of other creatures, including humans, and their thoughts, like some sort of Siren, and cause them to do things they wouldn't normally do!" The Doctor clapped. "Aha! So when you returned to earth a second time, you were like this!" The Doctor jumped around excitedly. "One half an Enpousaian, so you looked like a cancer victim. Brillaint disguise!" Thalia muttered something, but also appeared to be growing angry. "So! You had to kill Amy to live yourself and unfortunately Amy was your best friend, but you did it anyway." Thalia looked at the Doctor coldly. "You DID kill her, you manipulated her thoughts, but I can change them back! I've got it!"

Thalia came close to the Doctor and hissed like a beast. "Fine. Go back and save Amy like I wish, and blame me for everything, but believe me when I say this." Thalia then spoke again in her calm and loving voice. "I did love Amy, I do love Amy, and even though my race's goal contradicted her life and ended it, I still love her and want you to save her. Know that!" Thalia pointed at the Doctor. "I am NOT evil like most Enposaians. I would give up my life for Amy, and now I am!" Thalia began to disappear as she spoke her last words. "Save Amy for me, please…" She was gone.

Quickly as he could the Doctor put on his coat that hung from a chair on the TARDIS console deck, adjusted his bowtie and pulled back the lever to start the TARDIS. "Next stop…" The familiar sound of the TARDIS' revving engine filled his ears. "Leadworth, 2006! Giddy-up!" The Doctor stopped for just a moment. "I should never say that again…"
