Commander Harken: I notice your ship's called "Serenity". You were stationed on Hera at the end of the war. Battle of Serenity Valley took place there, if I recall. Independents suffered a pretty crushing defeat there. Some say that after Serenity, the Browncoats were through. That the war ended in that valley. Seems odd you'd name your ship after a battle you were on the wrong side of.
Captain Mal Reynolds: "May have been the losing side. Still not convinced it was the wrong one."
