Discord's plan while Fluttershy was away with the Breezies did not turn out as he planned. Not only did he not get to have the satisfaction of ruining Twilight and Cadence's day, he's now sick as a dog and bedridden. But at least Fluttershy is there to care for him.
However, while Discord didn't know of a certain giant worm's presence, he also neglected to consider one crucial flaw in his plan: how Fluttershy would react to it.
This fic stemmed from me being kinda unhappy with Fluttershy's role in "Three's A Crowd". Not the 'she's busy with the Breezies,' I felt that was a decent way to keep her from upsetting the plot, since it sets up a future event, and Discord came in BECAUSE she left. I more am unhappy we didn't see her react more to what Discord did behind her back, thus this fic is kinda what I imagine happened once she and Discord were alone.
I imagine that Fluttershy has Discord pegged, as she had him pegged BEFORE getting to know him better. That's my perception anyway.
