if Lelouch and Orange worked together as a team like that, Lelouch could probably geass someone over and over and over again.

While I like Lelouch and support his side (OotBK FTW!), that's a terrifying thought. But at the same time, it seems a bit of a cop out. Lelouch's inability to Geass someone more than once was an interesting obstacle to see him overcome because it meant he had to be more cautious with when and how he used his Geass. It also meant he had to rely more on tactics than just his Geass alone. Adding Orange's Canceller into the mix might take that away.

Then again... It would be amusing to see Lelouch geass someone over... and over... and over...
