Can't say I'm familiar with the Leno/Conan thing.
LadyWarrior might be, she likes Leno.

However, what you said is so true.
There is no way to explain Lelouch's actions in the Zero Requiem as anything but either a total scam (meaning he really didn't kill all those people) or total insanity.
Also, if Mr. I don't want anyone else to get hurt Suzaku was true to his belief in making Lelouch become a hero, WTF happened?
How is killing more innocent people going to wash away the death of Euphie or the evil that Lelouch accidentally committed?
What were Taniguichi and Okouchi thinking?
They should have had Lelouch go down as a real hero and save the world from either Schneizel or Charles.
I know I sound like a broken record about this, but it really was A MISSED MOMENT OF AWESOME.

Even in my story, I still had Tohdou acting like he did in the series, albeit a bit older and wiser.
