Yeah, that surprised me a little.
I would have loved a bit more characterization, but I realize there isn't a whole lot they can do in 40 minutes. That storyline could have taken up half a season but it probably would have felt spread pretty thin by that point, along with being exclusionary to anyone who joined in the middle.
I think if Lauren Faust had a greater amount of time and a larger budget she'd be rivaling Pixar.
Unrelated, does anyone have the "Discord was someone's kid once?" pic? I thought it was cute but I forgot to save it. (Stupid me.)
