[spoiler]Simply not answering or hanging up would still be very suspicious. Don't forget that Lelouch was expecting to talk to the new governor-general. The only non-suspicious response to suddenly being called "Onii-sama" would be to clarify that he did not know her and to ask if she was mistaken. His cover could be blown already just from his gasp and then his prolonged silence during the phone call. He is lucky that he bothered to turn around first so that Suzaku couldn't see the obviously guilty look on his face. Lelouch would be instantly screwed.[/spoiler]
And once again, I say that Suzaku is an ass.

[spoiler]while the welcome back festival was going, there was a panning shot of "the wall". this is the same "the wall" which Lulu made that one girl carve a symbol into every day. It appears that Lulu's geass does wear off after some amount of time, and it just happened to be when that girl was halfway done carving the symbol into the wall one day.[/spoiler]
Maybe this comes into play somewhere down the line, hmm?
Excellent catch. This could also mean that...
[spoiler]Lelouch can Geass someone a second time after a certain amount of time. It has been over a year since he Geass'd everyone, afterall.[/spoiler]
[spoiler]Suzaku is no longer invinsible, having been Geass'd the command "LIVE!" However, that also means that they won't be going into detail to this little plot-device. The only time it came into play was once when he was facing the Chinese Federation and had accepted that he was going to die. His eyes blinked the Geass orange, and nothing else happened after that. In that sense, it would be disappointing if that were true.[/spoiler]
One of your links in your last post leads to a public-restricted picture.
I have a pretty good idea of what it is and don't really need to see it, but I thought I should let you know if you didn't already.
