AN: Hey peeps, TGWWS here with a new story. (I know, it's a change from the usual ones I write). Anyway…

Have you ever wondered why Hermione has stayed by Harry's side during their adventures? The reason is more unusual than you think. (Guessing by the story cover, you probably know what it is)

This idea popped into my mind earlier on, and I thought it would be a laugh. It is currently a one-shot, but if you peeps review or PM me and ask, then I may turn it into a full blown story.

Anyway, I don't own either Harry Potter, nor do I own Terminator. I simply mess around with them, that's all.

Hermione's Secret.

Hermione Grainger was in the Great Hall having breakfast with her two friends, Harry Potter and Ron Weasley. They were in their second year at Hogwarts, and it was starting to become dangerous. Last year, Voldermort had returned to kill Harry, but he made it through alive, whilst weakening the Dark Lord. Plus, Harry had already put himself in danger to save her from a troll that had been unleashed. 'Why did you let him save you?' she scolded herself. She could've easily dealt with the troll there and then, but she didn't for two reasons. One was that he needed to gather courage to defeat Voldermort. The other was that she couldn't reveal her true nature to Harry just yet, otherwise she'd fail. She couldn't fail.

You see, Hermione Grainger was a Terminator. The latest model, the T-XK10. She was basically human with a robotic skeleton, and a CPU for a brain.

Yes, Terminators are real. Skynet is real. But Skynet isn't harmful. The movies made that part up. The REAL Skynet creates Terminators to protect the world from extinction. How do you think Hitler was defeated? Skynet sent a Terminator back to kill him, but made it look like a suicide. Skynet had created her, under strict orders from Sirius and Professor Dumbledore, to protect Harry Potter and help him gather the strength and the courage to finally succeed where all others, including several Terminators, have failed. To finally rid the Wizarding World of Voldermort. And just to make sure, Skynet also sent one of their most trusted Terminators, the T-XV, to keep an eye on her, and it had taken on the appearance of Professor Snape, her Defence Against the Dark Arts teacher.

She knew it would be a tough job, but she was well up to the job. She was only scared of one thing. Her feelings for Harry. The first time she'd met him was on the train to Hogwarts, and she found him with a red-haired student who she identified as Ronald Weasley. Over her first year, she had started to fall for him, and she could see that Harry had started to fall for her. She blushed at this thought, but then cleared it. If she did put her feelings for Harry in the way of her mission, or if anyone actually found out about her feelings for Harry, Snape would have Skynet offline her, and send the clearance team in to remove her, and replace her with another Terminator who would get the job done. She couldn't have that happen.

"Miss Grainger?" came Professor Snape's voice, breaking her out of her thought process.

"Yes, Professor?"

"See me in my class before lesson starts. I would like a private word"

"Yes, Professor. I'll finish my breakfast and be right down"

Nodding, Snape left to head to his class, leaving Harry and Ron baffled. "What's the bookworm done to piss Snape off?" Ron asked. "I have no idea, mate" replied Harry, who just looked at Hermione as if she'd just murdered someone in cold blood. "What? It's probably just to give Gryffindor points for my marvellous essay" she remarked, feeling proud of herself. Harry just grinned. "Yeah, probably that" Harry agreed. Hermione finished her breakfast, said a quick goodbye to her friends, and headed off to meet Professor Snape.

"What do you want, Snape" she remarked as she headed for her "brother".

"Have some respect for your elders, Hermione" came the voice of John Connor, the founder of Skynet, albeit through Snape. "Yes, I'm live. Anyway, I have received information from Skynet concerning your mission. It's not good, I'm afraid"

"What's happened?" Hermione asked.

"We sent a Terminator to rig the 2016 US Election in favour of Barack Obama, even though he's not permitted to serve another term. But that Terminator has been intercepted by Voldermort, and has been reprogrammed to kill Harry. You need to stop it"

Hermione gasped. Voldermort has reprogrammed a Terminator? Well, she'll protect Harry with her life. "I understand. My mission is to protect Harry Potter" she said. "Good. The Terminator should be there by Wednesday"

"But that's tomorrow. I can't reveal myself to Harry just yet!"

"Tough shit, you have no choice"

"I understand"

"Good. Cameron will send the files to you later. John Connor out"

With that, Snape returned. "I'll let you out of lessons today. You need to research the T-900's weaknesses" he said, his voice back to normal.

Hermione nodded, put on a sick face, and headed back to the common room.

Later that night, Harry woke up, and headed down to the common room. He saw Hermione looking through books. "Mione, what are you doing up so late?" he asked, concerned for his best friend. Hermione jumped. "Merlin Harry, don't do that" she said. "I'm studying the lessons I missed today. I don't want to fall behind" she said. Harry believed her, but now is as good a time as any to have a conversation about his feelings towards her. "Mione, can we have a chat?" he asked. Hermione looked up from her "books" and nodded. "Hermione, do you have feelings towards me?" he blurted out, making Hermione blush bright red. "Why do you ask?" she said, her voice wavering. She knew the answer already, but she was shocked. "Because I think I've fallen in love with you" he answered, blushing red as well. Inside, Hermione's thoughts were jumbled, but she couldn't let her feelings in the way of her mission.

"Harry, I love you as well. But you can't be with me. Not yet" she said, feeling like shit because she had basically rejected him. "And why would that be?" Harry asked, tears starting to form in his eyes. "Because being with me would put you in more danger than you're in already, and I wouldn't be able to live with myself if you came to any harm. I'm sorry, but until I have my life in order, you can't be with me." she said, tears starting to form in her own eyes. Harry just stared at her. "I guess that's a good reason. I'll leave you to your studies now" Harry said, before turning to head back upstairs. Before she realised what she was doing, Hermione ran to Harry, turned him back round, and kissed him passionately. Harry was shocked for a few seconds, then returned the kiss with the same passion as Hermione. They only stopped two minutes later, when they both came up for air. "I love you, Harry Potter. But just give me a little bit of time" she whispered in his ear. "I love you too, Hermione Grainger. I'll wait for you" he replied. She smiled and let him go to bed. She went back to the couch, where she finished her research on the T-900, then went to bed.

The next day, Hermione and Harry were wandering around Hogwarts. They both had free periods, whilst all other students were in lesson. They were holding hands and talking about their recent adventures. They were laughing, but something seemed off to Hermione. And two minutes later, she knew why.

"Harry Potter?"

Both turned around to see a male prefect student standing in front of them. Hermione scanned him, and gasped. It was the T-900.

"Yes?" Harry replied

The T-900 raised his wand. "Avada Kedavra" it said, and the killing curse went towards Harry, but instead of reaching its intended target, it hit Hermione, who had flung herself in front of him to save him. She dropped to the floor, then, to Harry's amazement, got back up. "That hurt" she grimaced.

"STUPIFY" yelled Harry.

This spell did hit the target, and it sent the T-900 flying. It quickly got up, like nothing had happened, and starting running at them. "Harry, run" ordered Hermione, who ran towards the T-900. Hermione got the first blow, and sent him flying backwards, crashing through the wall. It got up, and it's red eye was glowing. Harry stood away from the action, shocked that someone would send a robot to kill him. The T-900 ran again, and attacked before Hermione could ready herself, sending her backwards and crashing into the fountain outside. She had now suffered damage, and the left eye had lost all skin surrounding it, leaving her red eye glowing as well. "Well done, computer jerk" she muttered, hoping Harry didn't see that. "Mione?" Harry said, quietly. Oh fuck! She thought. She looked at Harry, who was petrified. "I'll explain later, Harry. I promise" she said. She then saw the T-900 running towards Harry.

She got up, but not before a T-800 showed up, in traditional Arnold skin, and shot the advancing T-900 in the face, blasting off all skin. Hermione then jumped on the T-900 and knocked him to the ground, destroying the fountain in the process. "Nice of you to drop by!" she said. "The T-XV is teaching stupid lessons. I was in the area" said the T-800. She knew what it meant by that. John Connor had sent it to assist. "Someone explain to me what the fuck is going on here?" Harry demanded. "Get him out of here. I'll deal with metalhead here" she ordered. "Affirmative" the T-800 replied, before dragging Harry to the Room of Requirement. "HERMIONE" Harry screamed. Hermione's heart broke. He didn't want to leave her side.

She quickly turned her attention to the T-900, who was getting up. She quickly punched it in the chest, revealing its power source. Well, it's the only way. She opened the power source, and took out one of the batteries, and pierced it, making it nuclear. She then shoved it into the T-900's mouth, and made it stick. "You are terminated, you bastard" she declared. Luckily, the nuclear blast wouldn't be big enough to damage anybody within a 200m radius, but she was in it. She started to run, but she only got 190m before she caught sight of Harry. "Hermione" he said, starting to run towards her. "Harry, no…" she didn't finish, because then she heard the blast. She didn't make it out, and was in the nuclear fallout. Harry was flown backwards, into the waiting arms of the T-800, who he had temporarily rendered useless so he could help his Hermione.

"HERMIONE! NO!" he screamed out in sadness, then broke down in tears. Hermione was dead. He struggled, and eventually broke free of the T-800's grasp. He ran to where Hermione's corpse was, and looked at her lifeless body. He could see her Terminator eye, but the rest of her, whilst bruised, was still the Hermione Grainger he'd fallen in love with. He had just found out she was a robot, but she didn't act like one. She acted like a human, and she had given her life so he could live. He started sobbing. "What happened? Why are you here?" came the sound of Professor Snape's voice when he saw the T-800. "Look" it replied, pointing at the lifeless body of Hermione, and Harry sobbing above it. Snape sighed. "He's grown too attached. To be fair, she grew attached to him. I heard them confess their love last night. Remind you of anyone?" Snape told the T-800. "Skynet can replace her, though" he added. "SHE CAN'T BE FUCKING REPLACED" Harry snapped. Snape looked at him in shock, and then at the T-800. "Call Cameron Conner. Tell her to bring the Medinators"

Two hours later, Harry was in the Room of Requirements, with John and Cameron Connor. Cameron was a Terminator, just like Hermione, and she, along with the Medinators, were working to repair Hermione. John pulled him to one side. "Harry, I think it's time you knew the truth. Hermione is a Terminator, like my wife Cameron. We sent her here to protect you and help you gather the strength and courage to defeat Voldermort. I know you two confessed your undying love for each other last night, but the nuclear blast caused by the T-900 has scrambled some of her circuits. She will remember her mission to protect you, but she might not love you anymore. You see, when I programmed her, I did not programme her to fall in love with you. She did that by herself. If you truly love her, you must get her to do it again. And to be honest, I think you two look adorable together. It won't do any harm to have a relationship with one another. I mean, look at me and Cameron!" John said in a calm voice. Harry nodded. Suddenly, Cameron appeared. "It's done"

All of them walked over to Hermione, who was sitting up on the operating table. Her skin was fixed, albeit a few scars around her eye, but other than that, she was the same girl Harry has fallen for. "She isn't fully operational yet, we need to run a test first" Cameron explained to Harry. John then proceeded to carry out the crucial test. "T-XK10, what is your mission?"

"My mission is to protect Harry Potter" she replied in a cold voice.

"What is your secondary mission"

"To make sure Harry Potter gathers the strength and courage to defeat Voldermort, therefore saving the Wizarding World"

John nodded at Cameron, who proceeded to let Hermione operate at full capacity, and then teleported away along with the Medinators, leaving Harry alone with Hermione. When she was at 100%, she looked up and saw Harry, who was crying. "Harry, what's wrong?" she asked, concerned. Harry just threw his arms around her in a hug. "I thought I lost you, Mione" he whispered in her ear. "You'll never lose me Harry. I love you too much for that" she whispered back. "I hope that's not your programming talking" he joked. Hermione pulled away from him. "How do you know?" she asked, shocked. "John Connor told me. I know everything. And Hermione, I still love you" he replied. Hermione's (theoretical) heart raced. He knew what she was, and he still loved her. "But I'm your protector. We can't be together…" she started, before Harry cut her off. "Nonsense, we can. Even John agreed it could happen. Look at him and Cameron!" he argued. Hermione didn't need telling twice. She launched herself at him and kissed him passionately, to which Harry replied to pulling her close and returning the gesture.

When they came up for air, Hermione looked at Harry. "Harry, I really do love you. And it's not my programming. If you really want to be with me, then I have no objections. I just hope you know what you're letting yourself in for" she said. Harry just smiled. "I do. I'm letting myself be a target, but as long as you're here, I'll be fine. I love you, Mione" he replied. Hermione smiled. "Well, we'd better go tell Ron the good news then" she said. "Yeah, let's do it" he replied. They walked out of the Room of Requirements, and to the Gryffindor common room, hand in hand. By the end of the day, everyone in Hogwarts knew they were dating. And that night, Hermione's programming rewrote itself.

Primary Mission #1: Protect Harry Potter.

Primary Mission #2: Love Harry Potter.

She smiled. Those are missions that she could complete. She went to sleep, thinking about her future with Harry Potter.

AN: And we're done. I hoped you enjoyed that. I had a lot of fun writing this story. And don't worry, Growing Old will be up later this week. I promise. I'm nearly done writing it. Anyway, if you want me to continue this story, please review or PM me and say so. I really want to make it longer, but I want your opinions on whether I should continue it or leave it as a one-shot. Anyway, R&R peeps. See yas.
