Castle cutie Molly Quinn really got into the Comic-Con spirit by dressing up as co-star Nathan Fillion's character from Firefly, Captain Mal Reynolds! It took a lot of work for Molly to put the outfit together, but the look on Nathan's face was apparently priceless!
"It was worth everything," she told Wetpaint Entertainment and other media outlets. "I knew he'd like it. And it was fun for me because I loved Firefly, even before I did Castle."
