Family is something Discord has no real experience with. It's something he's never cared about or understood. After talking to Fluttershy about her own family, Discord decides to study the family dynamic in Ponyville.
A week later, he shows up at a picnic with a surprise: a teenage draconequus named Eris, who he says is his daughter...and Fluttershy is the mother!
