This is Nathan Fillion as he runs down the line of people waiting for autographs at the California Browncoats booth at SDCC on Friday. He had to be somewhere, but wanted to sign everyone's comics, which were Limited Edition Serenity: Better Days issue #1, specially printed for CA Browncoats to support his charity Kids Need to Read. Best $10 spent ever.
Btw, he was running to make a guest appearance at the Joss panel. Hated that I didn't get into the panel, but this Nathan run-in was a great consolation prize.
