Impromptu Firefly Reunion Starts Rumors

Did they lose their spaceship?

Nathan Fillion, formerly Captain Mal Reynolds/Tightpants of the short lived Firefly, posted a link to the above picture on Twitter last night with the simple comment of “Together.  Again.”

Since then, rumors have started flying about what brought together Joss Whedon with members of his former cast.  It’s probably something as simple as a 4th of July barbeque involving fireworks (Adam Baldwin and Fillion seem like fireworks kind of guys), but rumors of a reunion project will follow this group wherever they go.

What do you think is going on?  And why the cagey comment, Nathan?
