I’m actually going to take this time to write down my in-depth analysis of Roro’s Geass just to put my thoughts and the thoughts of others into words about how stupid Roro’s Geass is, and how it makes me an angry fanboy. The reason I find it so upsetting is that the little details I’m going to bitch about are probably considered unimportant and will never be addressed. So now, let’s look at each instance of Roro’s Geass and what it suggests. The times I will provide are according to gg’s release.
Use 1: Episode 1, 13:02

Kallen was fleeing with Lulu. Then we see the pendant and Kallen finds herself sitting on the ground as Lulu and Roro run away. Something fishy just happened and it has something to do with Roro.
Use 2: Episode 2, Important scene at 15:07

Roro yells “Too slow” in a disguised voice, something he seems to excel at (Random talents ftw?), and then disappears. The way he fades out instead of vanishing instantaneously suggests teleportation more than time-stop. Here’s the important part though. If it’s time stop, then there is no issue. If not, then either A: The Geass does not effect Knightmare movement, and Kallen and Urabe remain in motion during the Geass since both pilots should still be pressing the gas pedal or its equivalent, or B: The Geass does stop Knightmare movement. If A, the only reason Kallen and Urabe don’t crash into the wall at the bottom of the screen is because they had put the brakes on before Roro used the Geass, since otherwise, they would obviously reach the wall at the speed they were traveling before Roro would reach the point he ends up at in front of Lulu afterwords. If B, they would simply stop and start as though nothing had happened. One more thing, though. If A: Even though they would come to a halt eventually had the brakes been applied, the fact that they were in motion at all means that, to them, they would appear to have moved forward a bit instantaneously themselves, since they would be unaware of their movement during the Geass. Why they don’t realize this can only be explained by the idea that they were distracted by Roro’s apparent teleportation.
Use 3: Episode 3, 11:26

The ugly blue circle is what I added in to make Roro’s position clear. The red circle is the area of effect of his Geass. It seems rather clear that it is supposed to be a perfect sphere, though whether he can change this shape to one that is more ovoid to affect only certain people is unknown. The scene immediately disproves teleportation by showing the frozen people, however, it also disproves time-stop, because the waterfall behind Viletta never stops flowing. I failed to notice this, but other more observant people saw it and pointed it out. So, as of this point, it would seem he has a mind-affecting geass that appears to make people unaware of time’s motion without affecting time itself or physical things like water and the light reflecting off of it.
Use 4: The end of episode 3 and the beginning of episode 4.

The picture is from the flashbacks at the beginning of episode 4, but I’ll also discuss the Lulu x Roro standoff now. At this point we are told told that it is a mind affecting Geass outright, but at the same time, we are shown scenes of murder that discount that idea. Unless the image above is supposed to be a still image, what we see and hear is Roro shoot a man, but the victim remains standing. If it is a mind affecting Geass, than the shot would have to have been non-fatal, since a dead man would cease all brain activity and would no longer be a living being under the effects of a Geass. If you don’t understand what I mean, you have to remember that time isn’t stopped, but instead, everyone within the red circle is merely stunned mentally, in the same way that people don’t move while Lulu gives them Geass-influenced orders. So when Roro kills someone within the circle, wouldn’t their no longer active brain be released from the spell?
If not, then this scene and the scene where Roro takes Lulu’s gun both demonstrate that people being affected by the Geass remain in the exact positions they were in when it started until it is over, meaning that anyone piloting a Knightmare would indeed remain in motion as they most certainly would still be pushing whatever button/lever makes it go forward. However, my earlier suggestion that Knightmares may be affected is also partly disproved by the fact that the camera in the room isn’t affected, so electronics are probably immune. Lulu’s counting of the seconds also serves to once again prove that time is not actually stopped.
Use 5: Episode 4, 17:14

And here’s where everything gets fucked up. Here’s why I made this post. What the hell. I was so damn confused when this part happened. Let’s begin. Knightmare navigational computers ARE affected. It would’ve been perfectly simple to just show the blue target that represents Roro jump from place to place like the two red dots and Lulu do, but NO. The computer clearly “loses” the target as he fades in and out. if the computer was unaffected, Lulu would see it jumping, but the computer would trace it perfectly. The only thing that could possibly prevent me from confirming that the computer IS affected by the Geass is someone else’s idea that the Vincent itself is able to momentarily disappear on radar, and that Roro uses that to further confuse people. Secondly, as I said, the two red dots and Lulu jump as well, meaning that they are most definitely in motion during the Geass. Tell me. If you were piloting a fast moving vehicle headed straight towards two other fast moving vehicles and you suddenly started to appear to teleport closer and closer to the other two without your control, would you not slam on the brakes? I see no reason why the two people approaching Lulu don’t freak the hell out. It’s not even about keeping your cool. Anybody who isn’t an idiot would attempt to stop moving if they could no longer control the rate of their own forward motion. So what’s going on there? Did Roro somehow only Geass Lulu, or were the other two pilots unfazed by the fact that they had apparently just teleported three times? If the Geass doesn’t affect bullets, waterfalls, or cameras, why does it affect nav computers? To put it simply, if they don’t explain the electronic disruption or whether Roro has the ability to change the shape of his area of effect, than Sunrise just screwed up horribly with this last scene. And yes, I am thinking too hard.
As a final note, I got nearly a tenth of my blog’s total hits in the last two days, so I know people are actually reading my blog for once :V. My point is, please comment if you have any thoughts on the matter, because I am sad and lonely, and I need your comments to justify my existence it would be nice to hear others’ theories or opinions. Half the fun of Code Geass for me is all the random, baseless speculation
