Disclaimer: I still don't own Code Lyoko. Not for lack of trying.
Freed from the mists of memory, Aelita finds herself on her knees with a boy standing in front of her. While the teenager resembled Jeremie Aelita knew it couldn't be him. Rather than being the one she missed with her entire being, this caricature aimed to taunt her. The ashen hair, pale face, and black shirt and shorts made her realize who it was. She opened her mouth and breathed out the name of her mortal enemy: "X.A.N.A…" The boy smirked and coldness radiated from him while a crimson X.A.N.A. symbol materialized on his black shirt. Running a hand through his ashen blond hair, this Jeremie doppelganger resembled a clearly evil vampire.
"I'm surprised you're still functioning. I analyzed that a hundred lonely years on Lyoko would snap your mind. But as always you're determined to prove me wrong. How has that worked out for you so far? I return with the same offer I gave you all those years ago. Renounce the humans and help me eradicate them from existence. Then again, there really aren't many left." X.A.N.A. chuckled menacingly. Aelita reeled in shock at his words. 'A hundred years? How much longer must this go on?'
Aelita gazed around at the silent hills and mountains that surrounded her. A hundred years wandering this virtual world alone. Once more, despair crushed her soul as X.A.N.A. waited for her response. 'Is defying him even worth it? What he did to me left my life in ruins but almost anything is better than this twilight existence.' Running a hand through her pink hair, Aelita smiled ruefully at that human habit. Here she felt nothing except her internal agony.
Even though the landscape had been under her scrutiny countless times, it revealed a new truth to her. This land had been her prison for years but she was still able to fight. Humanity had been betrayed by technology and the world was in the evil AI's hands. X.A.N.A. had made one critical misjudgment. Aelita was still alive and she remained the only one who had a chance of stopping humanity's slow destruction.
Aelita struggles to her feet and then looks back into those eyes. Over her initial surprise at seeing them, she could tell the sapphire orbs weren't Jeremie's. Instead of sweet warmth X.A.N.A.'s only emanated malicious ice. Aelita considered surrendering once again but the thought was instantly swept away by a surge of rage. Her face tightened in anger. 'No matter the consequences to myself I will never give up fighting. It's the least my friends deserve.'
"No! You don't understand how humans really are. Sure they're chaotic and unpredictable but out of the illogical stew of their actions come some of the greatest things on Earth." A spark shone in her eyes as she thought about the hours spent talking with Jeremie and her other friends. Aelita learned so much from them and they never complained about the debt she owed. Friendship, happiness, and love changed who she was for the better. 'Even if it has been a hundred years, and there are countless years ahead of me, I will have the memories of laughter and life to sustain me.'
X.A.N.A. wondered why Aelita even bothered as he watched her outburst. He had crushed her a hundred years ago and yet she still persisted in defiance. Those paltry human emotions were powerful in certain cases. Well, what a hundred years of isolation couldn't do maybe ten seconds of action could. He uttered a cold chuckle as a plan formed in his mind. 'So, Aelita missed her true love as the humans call it. That love will be her undoing. A twisted version of Jeremie didn't work; I'll try the real thing.' Focusing his vast processing powers, X.A.N.A. morphs into a perfect replica of Jeremie based on ancient supercomputer files. Before making his move he reprogrammed Lyoko to ensure that Aelita would feel it.
Aelita stood transfixed as all of a sudden Jeremie stood before her. Even though part of her brain yammered that it couldn't be real, the virtual girl's brilliant emerald eyes still feasted on the sight of him. The sheer emotional storm raging inside her masked the subtle change in her code. Giving Aelita's conflicted mind no chance to gather itself, Jeremie's soft kiss shattered the last vestiges of her self-control. The first physical feeling in a hundred years raced through her nerves and allowed the dreaded remembrance to surface. Finally freed, the memory of the first kiss swallowed Aelita's soul. X.A.N.A. released her and the girl slumped to the ground with staring eyes, already lost in the depths of her mind. The Jeremie clone smirked at how easy that was.
X.A.N.A. released a triumphant laugh at another plan executed flawlessly.
