Jaynestown
The 7th episode chronologically, Jaynestown was the 4th episode aired by the FOX network. Jayne and the crew arrive on a planet where Jayne is worshipped as a hero for what was actually a criminal act he committed, unknown to the townspeople. Hilarity ensues.
Objects in Space
Even though Firefly was cancelled, it's (chronological) final episode certainly function as a beautiful (albeit it unfair) finale. When an insane bounty hunter boards the ship to capture River, his interactions with each crew member give us beautiful insight's into each individual's personality. And also, River is a ship. This episode was the second-to-last episode aired by the FOX network, followed only by the pilot episode, Serenity. (Yes, FOX is that stupid.)
Our Mrs. Reynolds
6th episode chronologically, 3rd episode aired by the FOX network. The lovely Christina Hendricks plays Malcolm Reynold's newly (and accidentally) wed wife, who then turns on Mal and his crew.
Out of Gas
The 8th episode chronologically,Out of Gas was the 5th episode aired by the FOX network. In what many consider Whedon's finest work, the episode begins with a shot of Malcolm Reynolds alone and bleeding to death on his ship. A series of flashbacks show us how Mal met each of his crew members, as well as the 72 hours that led up to the Captain's current situation. While "Out of Gas" being Whedon's single best episode is arguable, what can't be argued is that it is a work of art.
War Stories
Niska returns and holds hostage - and tortures - Mal and Wash. Zoe arrives and rescues Wash, and River finally shows off her assassin skills - perfectly shooting killing 3 men with her eyes closed. Also, Wash decides that Zoe and Mal have too much sexual tension, and Mal lets Zoe know that her husband wishes for them to sleep together to get all that tension out. The 10th episode of the series, it was the 9th one to be aired by the FOX network.
Serenity
The 2 hour pilot episode that introduces each character and the entire show, this episode was the first of the series - and the last one aired by the FOX network. Because, you know, that makes perfect sense.
Bushwhacked
The 3rd episode of the series and 2nd episode aired by the FOX network,the crew of serenity come across a ship attacked by Reavers - and are accused by the Alliance of being the perpetrators of the crime.
Ariel
The 9th episode of the series, Ariel was the 8th episode aired by the FOX network. Simon gives the crew of Serenity a job to do: he tells them how to rob an alliance hospital for drugs worth loads of money, and they in turn sneak him and River into the hospital and allow him the time to examine her brain with hospital equipment. Jayne tries to turn in the siblings to the Alliance, but his plan fails and Mal threatens to throw him off the ship.
Trash
Mal's fiendish wife Saffron (played by the gorgeous Christina Hendricks) returns with a plot to steal an incredibly valuable gun from a man who turns out to be another one of her husbands. The episode begins and ends with a naked Malcolm. Nice, yeah? The 11th episode of the series, this was never aired by the FOX network, but was the first episode the Sci Fi network aired.
The Message
A touching episode about the fake-death-turned-real-death of one of Zoe and Mal's wartime buddies, that also features Jayne's fantastic hat. This was the 12th episode of the series, but unfortunately this gorgeous episode was never aired by the FOX network. Instead, it was aired by the Sci Fi network the summer after the show was cancelled.
