13:12 Hi! I just wanted to highlight, his look is very much fashioned after the look of King, the chess piece in the anime. Don't worry, the chess piece will be shown multiple times throughout the show, you'll get to see it. Also, like mentioned before, he's making a spectacle of all of this. You will see it by the end of the show but everything starting with his look was all to make the "Zero" an icon to the entire world... and for good reason. One more observation I've made. The word "zero" is first mentioned in the show by Suzaku... when talking about the possibility of Lelouch's & C.C.'s survival with Cecile. She said the possibility of them surviving is near zero, then Suzaku says "but it's not zero, right?". Brilliant directing.
That part's not very straight forward. Geographically it's North America but they did a historical rewrite where the British royal family had to flee to the colonies and continue their empire there. So technically the country is England because the United States didn't exist.
