Episode tag/companion to "Discordant Harmony". Written in second person for some inexplicable reason, but the "you" being addressed is Discord, not "Reader" or "Anon" or something like that. In the course of trying to make sure Fluttershy is impressed by his tea party, Discord discovers some things. Some of them are good things. Some of them are very much not.
Notes:
The story deals with the concept of being suicidal, which you might possibly guess if you watched the episode -- or at least, the concept of giving up and letting yourself die. It also explicitly states Discord's interest in Fluttershy to be romantic as well as friendly, though at this time Discord has no idea whether this is reciprocated or not and thinks probably it's not.
