Dark Qiviut

Like the original, Celestia brings the statue of Discord, but only to Fluttershy and Dash as the others aren't there. Rather than simply saying that Celestia would like to have Discord's powers used for good, she explains that she forgives Discord and believes that Fluttershy is the best pony to help him reform. In case he does anything evil, Celestia created a necklace made out of broken shards of the Elements of Harmony, which will cause him to wake up when it's donned on his statue. When he does something bad, he gets zapped. Only when he's committed to being a good guy will the necklace come off.

Not long after, Discord wakes up from his stone slumber, and right away, he's up to his usual chaotic tricks. Even though he's intentionally driving others batty, the necklace mostly doesn't zap him. But FS doesn't give up on him. During the tea party, he plays music loud and softly to play with them, ruining it. He explains that he's basically a chaotic guy and crashes on the couch because. Fluttershy had enough of his attitude and gave him the stare. Cue the next morning, our heroes discover he's no longer wearing the necklace, initially assuming the worst, only to find out that's not the case.

Cue a flashback. The stare contest between FS and Discord lasted all night through the morning, when he gives up. Soon, he discovers that beavers were trying to competitively build their own dams, which risked overflowing a nearby creek. FS convinced them to stop; Discord admitted it felt good being helpful. The necklace fell off. And he's allowed to crash on the couch anytime.

Needless to say, this episode is really, really crammed like the original. The fact that Discord's controlled until the necklace falls off really opens up several implications, such as slavery, "friendship = control," and so forth. In the final, Discord discovered his feelings and like for friendship when he realized he was manipulating her and regretted it, a much more satisfying conclusion over this. However, that infamous line from the actual episode suggests her friendship with Discord is a means to control, too, so it isn't any better.

Also, despite supposedly being a judgment of good and evil, the necklace is extremely incompetent; he's intentionally doing many bad things to get under everyone's skins, but the necklace lets him get away with it. However, everyone puts their trust and support for FS, and Twi doesn't try to find a spell to force Discord to reform. And I'm not sure about how the necklace is made up of broken pieces of the Elements itself, though I haven't read the other premises to see if that's true to that continuity at the time.

Honestly, the original premise and final are equal, but if I have to choose which is better, I have to go with the final by a small margin.
