Compilation of fact/theory on Why lellouche is still alive

Second, however, and this is where the others have thought things through, Lelouch is alive because he got his dad’s code. He beckoned the World of C to lend him its powers, and he took Charles’s code before Charles passed on. The reason why Lelouch still has his Geass is because he didn’t take the Code from the same person who gave him his Geass: he took his Geass from CC, and he took his Code from Charles. Thus, he now possesses both immortality and a Geass. This is also a reason that the title is Code Geass: Lelouch of the Rebellion.

To further corroborate this, however, remember that when Nunnally held Lelouch’s hand he transferred his memories to her. CC also did it when Lelouch touched her accidentally back then, so it could be assumed that people with Codes are indeliberate telepaths. This leaves us with both immortals traversing the world for the rest of eternity.

There is a scene where CC is praying in the church as Lelouch is about to be stabbed by the sword. At first glance, you might think the “punishment” for using Geass was death… However, why would she see that as punishment when she herself had wished to die so badly? Rather, she regarded immortality as a curse… And so the punishment of the Geass is that Lelouch would now be immortal.
10. The fact that CC says “Geass is the power of kings, it will isolate you… well, I guess thats a little wrong… eh, Lelouch”. is definite proof that lulu is not currently isolated in the world C. Also CC has once said that she sees the dead as painful memories and has never spoken to them before. Thus its not likely she would be talking to somebody who is dead.

1. Charles grabbed Lelouch with his right hand, which had the Geass sigil.
2. Lelouch needed the fully evolved Geass to transfer a code.
3. The code doesn’t appear to activate until someone dies. Hence, why C.C. was wounded when she first inherited her code. Same happened with Charles in the World of C.
4. When Lelouch touched Nunnally, Nunnally got a flash of his memories. This ONLY happens when a high potential Geass user touches someone with the fully evolved Geass.
5. The title of the series is “R2″, which is similar to how “C.C” is pronounced. So Lelouch would be “R.R.” which is Engrish (I presume) for L.L., Lelouch Lamprouge.
6. When C.C. is talking on the wagon, she says “the power of Geass brings loneliness…that’s not quite right is it, Lelouch?” and nods her head in the direction of the wagon driver.

Lelouch is still alive. He has Charles' Code which he received when the man choked him. The Code activates first when you die, which happened. And before you say can't have Code and a Geass at the same time, the Code wasn't the one C.C. had, meaning that Lelouch was the first one to achieve Code Geass. He's now travelling the country-side with C.C., living as immortals.

That's the only reason for C.C. to be suddenly so happy again. Also, before you say that C.C. was just talking to the dead like with Marianne, that's not true. She could only talk to her because of the nature of her Geass which allowed her to implant herself into the "hearts" of others. That's how she was able to talk with Marianne. Lelouch's Geass was entirely different, meaning that she could only have spoken to him if he was there.

Also, the screenie of the cart driver who is masking his features competely supports this.

C.C. possesses the Code, which grants her immortality as well as other abilities, such as forming contracts to grant people the power known as Geass. Hers is not the only Code, as V.V. originally possessed one, later taken from him by Charles.
The Code Charles possessed until Episode 21 was taken by Lelouch either accidentally or on purpose, when Charles throttled him as he was about to vanish, devoured by the World of C.
However, Lelouch still possesses Geass, even after gaining the supposed Code. Why? Two possible reasons. Either the Geass remains until the Code is first activated, upon death, or Lelouch was the first one to achieve the “Code Geass,” having received his Geass power from C.C. whilst possessing a different Code from hers, V.V.’s.
What supports the idea that Lelouch has the Code and that it was no destroyed/devoured by the World of C is the fact that the geasses Charles had placed on Nunnally and Anya still held their effect. Geass draws its power from the Code, and had the Code been destroyed, the Geasses would have faded. That is why Charles’ Code still exists, now in Lelouch.
The Code is possibly located on his neck where Charles held him, or it appears on his palm when it activates upon his first death, obscured by blood from the wound in his chest.
When Nunnally touches him, she sees a glimpse of his memories, just as Lelouch did when he touched C.C. back in Narita. The reason for this is that the Code is activating for the first time, Lelouch possibly being unaware of this and unable to control what is shown unlike C.C. who forced shocking imagery into Suzaku’s mind.
As we see the memories flash by, we hear a sound effect, similar to the one whenever geass is used, though not the exact same, regardless confirming that a memory transfer is indeed what is happening. This is one of the main points that dictates why Lelouch is still alive.
Later on, in the ending, we see the cart driver, whose features are conveniently masked to cover any traces that might allow us to identify him as Lelouch, which makes perfect sense. Lelouch was the hated Demon King who seized control over the entire world, keeping everyone in check by threats of FLEIJA and so forth. It wouldn’t do well for someone to recognize him on the country-side.
The cameraplay in this scene is also an obvious indicator, they wouldn’t have gone to such extents to mask the features of a random peasant. Also, 2-3 frames of the animation show what appears to black hair under the hood and the hat, further supporting the idea that he is indeed Lelouch.
Finally, C.C. addressing Lelouch and tilting her head slightly upwards shows that she was indeed addressing the driver. This is pretty much self-explanatory. It’s also clear that C.C. would not have been as happy as she was had Lelouch truly died.
Therefore, with these solid facts, we deduce that Lelouch is alive, living out a secluded life, either traversing the countryside with C.C. or living with Jeremiah and Anya on their plantation.

1. The shadows under his eyes are 52% darker than the normal death shadows. This is not because he's more dead, it's because he's using mascara.

2. At 19:19 Lelouch's voice cracks a little. He's undergoing the effects of the code and having a hard time hiding it.

3. If you look closely, in the picture in Kallen's room you can see that Tianzi's skirt is puffed out more than it should be. Lelouch is clearly hiding under it.

4. Those horses pulling the cart are of the same kind used by the royal family, as can be seen during a flashback in R1. You can tell by the way their mane is parted and the color of their hooves.

5. Do you see that smug expression on Cheese-kun's face? Yeah, he's in on it.

The image of Lelouch the EMPEROR had to die. Lelouch himself has the code and does not die. When everyone touched Lelouch before no images or anything was seen even when he has FULL GEASS. When Nunally touches him after he dies she gets the same images Lelouch got when he touched C.C.

OK, so the Orange bastard, he knows all about the plan and puts it up for show and thus smiles when Zukaku stabs him. He himself stops everyone else and says he will fight Zukaku and just lets him hop over him with ease. Come on, it is damn obvious he knew of the plan. So yes, he knows all about the plan and yes Lelouch is the guy driving the cart or in the hay in the cart. All that is known is that is he is alive and isolated in the farmland with C.C.

Lies and memories are two completely different things. When she used that technique on Rohmeyer she had her repeat herself in order to discern whether she was lying or not.

If Nunnally had magical mind reading abilities then why didn't she know that Lelouch killed Clovis back when they pinky-sweared in episode 3 of S1? Or that he was Zero this whole time, they were shown holding hands on more than one occasion.

Saying Nunnally has mind reading powers with the evidence provided in the show is absurd. I can see many reasons for Lelouch having a Code, but Nunnally a mind reader? Give me a fucking break.
