Starswirl, you really need to check which idioms you use.
Also, wooooooooooo, Season 4 opener! How did you find it? I really enjoyed it personally; I think it's about tied with Season 2 as my favourite opener. Although, that locked container shown at the end has piqued my interest: is this going to form part of a season-long story arc? Will the Mane 6 have to go on a Legend of Zelda-style quest for the keys? Is this Discord's fault? And why not just try to open it with a sledgehammer?
Guess we'll be finding out these coming months!
