Hear that? It's the sound of thousands of fanatics rushing to their televisions and squealing with glee.

Tonight, Joss Whedon and the cast of the beloved Firefly will reunite for one hour, to give diehards a deeper look into the short-lived sci-fi series. Appropriately titled "Browncoats Unite," the special will feature cast interviews and footage of this year's Firefly Comic-Con panel. As grateful as we are for this special, maybe the excitement will catch on and Firefly will get the Arrested Development treatment. Well, only if Whedon isn't too busy making unlimited Avengers sequels.

The one-hour Firefly: 10th Anniversary special is on tonight at 10 PM on the Science Channel. At 9 PM tonight is the Season 2 finale of Upstairs Downstairs on PBS, opposite the one-hour 200th episode of Family Guy on FOX. Also on tonight is the Season 1 finale of Breaking Amish at 9 PM, followed by the Breaking Amishone-hour "Shunning the Truth" special at 10 PM, both on TLC.
