I'm actually in awe of how quickly he comes up with stories and characters. He can take a throw away character who was in the background and based on one thing a player says, he instantly creates a lore and personality of the character that becomes one of the best parts of the campaign. There's a drug dealing Werewolf named Jawbone who became my favorite character of all time. And yes, he knows everything. The guy is not only a legit genius, his neurons just seem to fire significantly faster than anyone I've seen. Plus he is just a flat out good dude.
