SPOILERS, Set After the Series Finale
"The power of kings, known as Geass, brings one solitude. Not quite accurate, is it? Right, Lelouch?" C.C. asked, raising her head upwards.
"What is solitude?" asked the cart driver.
"What a silly question! Solitude is the state of being or living alone," the green-haired woman answered, turning on her stomach, inching close to the edge of the hay cat, close to the driver.
"Solitude is also absence of human activity."
"Am I not human?"
"No, you're a witch," the cart driver answered, slightly turning his head and showing his passenger a slight grin.
"Using that one against me. Well, if I'm a witch, then you're a warlock."
"Well played," the young driver said before halting the horse. "Wait. I thought you said I was your demon." The tattered hood came off and revealed a violet-eyed, black-haired boy of nineteen.
"You were, but some demons grow up to become warlocks."
"Wouldn't they become devils?" answered Lelouch Lamperouge.
"Lelouch, I wonder about your logic."
With a gentle slap of the reins, the cart moved on.
"Why did you give up your name?"
"Because it was too human."
"Why did V.V. give up his name?"
"Because I did."
"So you're a trendsetter? Guess I'll follow in your footsteps as L.L."
"It's silly to follow me."
"I think it's fitting. Two Ls make L.L."
"Aren't you Lelouch vi Britannia?"
"I was, but Zero slain that man. All that remains is Lelouch Lamperouge."
"Don't think I'll be calling you that yet."
The duo said nothing afterward because they entered the main road where others traversed. Some might have excellent hearing. They talked, but as an elderly man and his daughter delivering supplies across the vast area of Central Britannia. Having fake conversation was awkward, but soon the hay was delivered to farmers and the two had money.
C.C. headed into town while Lelouch waited in the empty cart, warily watching passersby. Usually the curious wanted to look at this stranger's face, but a grouchy, raspy voice Lelouch threw discouraged them. There was a danger whenever Lelouch and C.C. went in public. C.C. always handled the crowded situations since people were more likely to recognize a dead emperor rather than the woman always at his side but never seen.
Hours later, C.C. arrived with a bag of food. After riding a few miles away from civilization, the two settled under a tree. Lelouch took over the head clothing, bit by bit. All the clothing was designed to fool others into thinking he was a hunchbacked old man. A black v-necked shirt and jeans were all that the young immortal warlock had. On his neck, a geass sigil stuck out against his pale skin. Of course the black shirt didn't help repel the hot region, but it was better that pounds of clothing.
"What, no pizza?" Lelouch when C.C. presented the bag of food again, and their conversation continued through bites.
"You know the marketplace barely sales that."
"What did you get?"
"Some turkey sandwiches and some fat-free potato chips. This region is a strange one. Instead of buying ingredients, people buy whole products, yet farmers make plenty of products like milk and eggs."
"That's Central Britannia. The meals used to be rice and beans when I was a child. I guess Empress Nunnally changed that."
Lelouch started to scratch at the sigil.
Narrowing her eyes, C.C. watched him. "It doesn't itch."
"How do you know?" he asked. "We didn't get our immortality the same way."
"I warned you. You obtained Charles's Code when he grabbed your neck, but you didn't believe me."
He took the last bite of the sandwich. "Of course I didn't. I assumed that the code owner had to willingly give up his code."
"It usually works that way. I shielded my code from Charles, and I had the power to force my Code on either Mao or you."
"But you didn't."
"Correct. Charles is unique because he was destroyed. You were the last Geass user he touched."
"Then what are the conditions of the forced Code? What if my Geass powers weren't fully developed? What if he didn't touch me? What if no Geass user wasn't present? Would you have obtained his Code?" Impatience caused his voice to rise because Lelouch Lamperouge didn't like to be in the dark.
"Oh, Lelouch," sighed C.C. as she threw back her head and looked in the sky. "Don't try to find logic in everything. Some things cannot be explained. Besides, Charles could have willingly passed on his Code."
"Unlikely."
They boarded the cart again. Lelouch had his disguise, but with light falling, he decided it was safe to have his face revealed. C.C. leaned on his side, looking at the approaching sunset.
"If you knew you were going to be immortal, would you have done it differently?"
"No. Maybe a few details here and there."
"Would Lelouch vi Britannia still be a symbol of hate?"
"Of course. Only I could do it." Of course, those bombs of mass destruction had potential.
"Would you have used your Geass on Nunnally?"
"Yes," he said, almost hiding the pain in his voice.
"Suzaku?"
"Suzaku Kururugi died in the final battle, fighting Kallen and her Guren. You know that."
"I see. Only Zero exists."
"Correct. It doesn't matter how the desired end is achieved. Worrying about how things are done would be something the late Suzaku would have done. Zero, Lelouch vi Britannia and I do not think that way."
---
Just to be clear. This is my opinion of how it ended. I actually can see it both ways, and I would be happy if he was dead or alive. I was going to make this a one-shot, but no, I'm going to expand it.
