The ones that the writers discussed on the roundtable discussion show the other day on the science channel they would have made had it not been cancelled?
If not, and going from memory there were some pretty bad-ass ideas that never aired:
* Mal and crew arrive on a planet with a few desperate survivors (planet is dying) and realize if they try to bring them on the ship with them, they'll all die unless they happen to run across another ship first. Mal locks crew in ship and alone makes the decision to take off leaving the people on the planet to die and they don't run into any ships meaning they would have all died if he hadn't made that decision. Mal didn't let the crew decide so he alone was responsible.
* Inara captured by reivers but keeps on hand a 'poison' she uses in her vagina to kill someone who tries to rape her. when mal finally finds her, he finds inara alive but a ship full of dead reivers
* jayne tries to lead his own ship and crew to compete with mal..fails miserably and begs to rejoin mal's crew
those are the ones i remember..i think there were at least 2 or 3 other ideas they mentioned.
