Someone recorded the Firefly panel at Dragon Con.
It's six parts total, very nice quality, all on YouTube.
The panel consisted of Morena, Jewel, Sean, and Summer, with occasional prank calls from Alan and Nathan.
-- In response to a question about River finding a love interest, Sean answers, "Besides me?" and causes every Tamcest aficionado to spontaneously give birth.
-- On that note, Sean seems to have a wedding ring and mentions a daughter. What the.
-- Jewel, Morena, and Sean apparently do pilates together.
-- Sean: "I never felt like it was a sci-fi show."
Morena: "Are you on crack? It takes place in space, five hundred years in the future, on a spaceship."
-- Adorableness abounds.
