"What About Discord?"
What indeed about Discord? How strange for the master of chaos to suddenly descend upon Ponyville, bond with his favorite friends besides Twilight Sparkle, and then use that bonding (coupled with sarcastic jabs and sly glances) to snarkily teach Twilight Sparkle a friendship lesson of his own in an almost season 4-ish manner. Certainly a genuine desire for deeper friendships with the other girls played a role in his actions, but what other thoughts and plans might have influenced his behavior?
Luckily, a few days after the end of this latest chaotic adventure, Discord shows up at Twilight's castle to explain his goals of the previous weekend and to hint at some of his friendship plans for the future (for Ponyville and beyond). And he begins by asking the friendship princess a simple question about his teasing this time around: was it too much?
The conversation that follows illuminates many things.
