The animation may take a few seconds to load with a slow connection, but when it does, pay close attention to Xanatos...

I love how the wind is blowing hard, just before it starts storming, and everything (even the watch tower!) moves... but not Xanatos! Not even the wind can make his hair and clothes move!

Is it possible that David Xanatos is so rich and powerful, that he's literally become untouchable? Even the wind is afraid to go anywhere near such power? Hmm...

Nah, I think they just didn't animate him!
