The second day of Comic-Con officially went by without a moment to waste. People were streaming in like crazy, lines going all the way down the trolley station. The Dealer floor was packed with famous people and big Smurfs walking down the hall.  The day didn't get exciting until I accidentally bumped into Nathan Fillion as he was fleeing the Browncoats booth. He was quickly trying to sign everyone's things as he was trying to leave and was trying to make sure everyone who'd bought one of the Serenity comics to benefit the Kids Need to Read organization got theirs signed. I found out later that he had come unannounced and no one knew where he was going or when he was going to be back. It was nice to see an actor from a great television show come down without telling anyone.
