Did you not know about any of the Firefly/Serenity comics?? There's one that happens between the show and the movie, one that is a prequel to the movie, then Book got a mini-series, and there was the Wash one-shot by Patton Oswalt and now the official continuation of the story, picking up a few months after Serenity. They are really good, though only up to issue 4 so no trade yet.

Thank you! Pinkie Pie is def my spirit pony LOL. Bit of a spaz, loves to plan parties (but parties help disguise the control freak tendencies underneath LOL)
