** It was stated in the Miraculous Birthday picture drama that it wouldn't work on it

*** He has fully awakened it, but it's still [[PowerIncontince stuck]]. He just uses two lenses now - see his gesture before using it, that's when he removes them.

** But leave him unable to be geassed again, I would assume?

*** From what I can tell, the two had thrown their will into the sword of Akashic. Once the sword was destroyed, so was Lelouch's parents.

** Is this good enough for a physical explanation? Charles and marianne's counsciousness are wiped out and their physical body have a stroke or something(leaving them brain-dead), then Lelouch dumped them out of some window or into the sea off-screen.

** The person who has the code would die. Rember, Shinigami are gods, and gods have been shown to be able to kill people with codes.

** They are not at all consistent with how Rolo's Geass works. Rolo should have clearly died in episode 2 of R2. [[spoiler:When Urabe stabs Rolo's mech and explodes, Rolo survives thanks to his Geass by "warping" out of the way. However, as his Geass doesn't actually stop time, he shouldn't have been able to get away from that explosion. While everyone else's perception may have been stopped, the explosion wouldn't have been.]] However, at other times, his Geass has worked exactly like it's supposed to. For instance, [[spoiler:when he Geassed Suzaku in episode 6 of R2 so that Lelouch could speak with Nunnally and when he helped Lelouch escape in episode 19.]] Sometimes Rolo's Geass works as advertised and sometimes it's more like he's warping around. If anything, I'd say that what is generally the case is that Rolo's Geass works as advertised when we see it from his point of view but it's frequently done improperly (i.e. it looks like he's warping and nothing else moves) when shown from anyone else's point of view. Of course, even that's not always the case (e.g. when [[spoiler:he Geasses girls at the school in episode 12 of R2, they stopped moving completely instead of falling due to their momentum]]). The definitely explained how Rolo's Geass works, so that's quite clear, but they don't always follow those rules when showing him use it.

** They had just tried to kill said thing. I imagine it was none to pleased about that when it was given the chance to express its opinion.

*** Geass can't control the body, only the mind. "Grow a third arm" might compel them to seek out cybernetic surgery, a cardboard tube to tape to their side, or a [[AustinPowers Swedish penis enhancer]], or maybe it would just make them stare at Lelouch for a few seconds. But it can't randomly induce mutations or anything.

** Probably it's more like a magnet or possibly even a liquidization thing. You know, like how [[{{Hellsing}} Alucard]] regenerates?

** The duality would likely cause both Geass powers to cancel each other out, returning Suzaku to his normal self.

* What would happen if someone, say, [[GurrenLagann Kamina]], was wearing reflective sunglasses, and Lelouch tried to use the eye on him? Assuming Leoluch hadn't Geass'd himself beforehand?

** Maybe her limbs would individually pull themselves back together, like [[StarWarsCloneWars Durge]].

* What happens if two Geass users have a "command type" power and give conflicting orders to an individual (ie: Lelouch used his Geass on Suzaku to order him to live in R1. What if Shin Hyuga Shaingu orders him to die? Who's Geass takes precedence?)

** Problem is Vimes' men are more GenreSavvy than that. By the time he started issuing genocide orders, Carrot, Aunga and Detrius would have him bound, gagged, and halfway to the Unseen University. Ponder Stibbons would take a great interest but have no insight whatsoever, Ridicully would do something funny, Colon would make a poor attempt as the bad cop in the "Good Cop Bad Cop" routine. Then Ventari would confront Lelouch (wearing a blindfold, obviously), while Lenoard of Quirm would send Nobby and Colon in his "[[TimeMachine Go Backwards In Time And Hopefully Not Kill Your Own Grandfather Device]]", where the two would specatualarly fail to change the past. Then some other stuff would happen and... um, never mind. Got off track there for a moment.

** It ends up killing him when he tries to do it repeatedly. The scene where he helps Lelouch escape shows him visibly struggling to use his powers. He even tries to activate it at one point during his escape and fails to.

* If Rolo's Geass stops his heart every time he uses it, how the hell can he use it for ''30 seconds'' and not die?

** The collective unconscious seems to be a composite entity with a will of its own, wherein every personality to ever exist is merely a small part of a whole. The collective unconscious ''underscores'' the mind of every human (hence the term "unconscious"), but it doesn't actually ''represent'' their individual will.

with the command for people to be Lelouch's slaves.

Geass works as advertised when we see it from his point of view but it's frequently done improperly (i.e. it looks like he's warping and nothing else moves) when shown from anyone else's point of view. Of course, even that's not always the case (e.g. when [[spoiler:he Geasses girls at the school in episode 12 of R2, they stopped moving completely instead of falling due to their momentum]]).

directly affected by a Geass.
definitely in his favor and it's not at all unreasonable that it paid off.
so that he could then mentally taunt Mao.

** The way I took it was this: the [[spoiler:Collective Consciousness]] was merely an inactive force, and Charles and Marianne's plan was to build a "bridge" to it then use the power of the Codes to force humanity to be totally honest. Lelouch argued that such a plan would destroy any future for humanity and Geassed the [[spoiler:Collective Consciousness]] to not let that happen. This results in the [[spoiler:Collective Consciousness]] absorbing Charles and Marianne (since C's World seems to be a spiritual realm rather than a physical one), preventing them from completing their plan. Note that Marianne seems shocked that C.C. isn't being absorbed, but she explains this by saying that she rejected their plan a long time ago, meaning the [[spoiler:Collective Consciousness]] doesn't see her as a threat.

* Outside of the moral concerns, I have some problems with Lelouch being able to use his geass to make people slaves [[spoiler: and to a lesser extent what he did to Schneizel]]. Given that the power is one use only for him, to give a command like that is almost like the proverbial "wishing for unlimited wishes" concept- you would think it is not an option. I'd expect, that for the command to work, it would render whoever he does that to incapable of anyting, even using the bathroom or breathing without Lelouch's command. [[spoiler: Ordering Schneizel to obey Zero]] makes a bit more sense, since the phrasing implies that the command makes the person have enormous good will towards Lelouch and thus they can still think independently while being ultra-loyal. At best, maybe this is what is supposed to have happened with the command for people to be Lelouch's slaves.

[[spoiler:When Urabe stabs Rolo's mech and explodes, Rolo survives thanks to his Geass by "warping" out of the way.

*** Exactly. The red rim around the eyes only appears when the Geass is directly affecting the person. For instance, the "Live" Geass command that [[spoiler:Suzaku]] is under only appears when his life is in danger and the Geass is necessary to keep him alive. When affected by a command to forget, they forget more or less instantly, so the command is no longer necessary. They've already forgotten, so they're not really under the effect of the Geass anymore and the rims around the eyes don't appear. No one who is affected by [[spoiler:the Emperor]]'s Geass ever has red rims around their eyes. Their memories are altered immediately when they're Geassed, so there's no need for the Geass effect to continue, so there's no red rim around their eyes. The red rims appear only when being directly affected by a Geass.
*** The red rims issue has obviously been addressed: it doesn't apply to commands that deal strictly with memory. As for why Mao didn't figure out Lelouch's plot, this is most because one of the conditions of Mao's Geass is that he needs to focus to use it. Yes, he always picks up surface thoughts due to PowerIncontinence, but we know that even this is reduced if Mao focuses intently enough on one thing. In order to pick up on the gaps in Lelouch's memory, Mao would need to, first off, suspect such a ploy in the first place, and then to dig far below the surface of Lelouch's conscious thought. This would require taking attention away from Lelouch's current strategizing...which, given Lelouch's brilliance, is probably not a wise thing to do. It may have been a bit of a gamble on Lelouch's part, but the odds were definitely in his favor and it's not at all unreasonable that it paid off.
** I had always assumed the red-rimmed irises were simply a visual cue for the audience, since they are never once pointed out by anyone within the show. In this case, showing them on Lelouche's eyes at any point in those scenes would have given away the ending. Assuming this is not the case, well... It's pure speculation to even try to guess why he didn't have the irises since we are never given any details of Lelouch's plan, nor his exact command to himself. Suzaku tells him, "After you showed me which wire to cut, you said to burst in when I heard you scream" (indicating at the very least that Lelouch executed a successful Batman Gambit on himself). For the sake of speculation, Lelouch could have gotten back in the elevator and given himself something as simple as, "Forget everything you just told Suzaku, and go confront Mao at the church face to face." Given what has already been established about how his Geass commands affect a person's memory, that would empty his mind of not only the master stroke, but also absolutely everything except whatever challenge Mao posed him (the chess game) and account for Mao's taunt of Lelouch showing up with absolutely no plan at all, as well as Lelouch's response to that taunt (not feeling wierded out by going there without a plan), whilst simultaneously allow the red rims to vanish while Lelouch was still off-camera (Reached church and am now confronting Mao: Done. Red eyes go away). It's pretty apparent by his actions that he never got those memories back, and that it was Suzaku's responses as well as knowing his own tendencies that allow him to deduce what he had done so that he could then mentally taunt Mao.

* If the Sword of Akasha is the collective unconsciousness of humanity's unconsciousness, then when Lelouch geases it doesn't that mean he's used his geas on all of humanity? If so that means none of his geases he uses afterwards on his slaves or Schneizel should work without the Geas Canceler since they've all had a geas placedon their subconscious already.

** Yes. He even does this in one episode at school where C2 was about to be discovered and radioed a student with a geassed command that resulted in a distraction.

** Let's just say, reflective sunglasses play heavily into the "Lelouch vs. ArtemisFowl" crossover in this troper's head. Lucky Artemis is wearing his anti-mesmer gear.
