Ep 1-07 Our Mrs. Reynolds
 

After a celebration in which the crew is honored for ridding a planet of a group of bandits, they return to Serenity to find a woman named Saffron stowing away onboard, and she claims that Mal married her during the festivities.

This one has a lot of humor to it and I love it. We actually get to see our group of Con artists and thieves conned and robbed. (Plus, that Saffron chick is hot.) And we get to see some of the other dangers our crew faces, when they're not dealing with scumbags, Aliance and Reavers.
