I'd appreciate if everyone could keep the YouTube embeds in the comments to a minimum. The sheer number of them is putting a bit more strain on my connection than I'd like. I'm going to start deleting any comments with 2 or more embeds in them.

When Sombra, ex-ruler of the Crystal Empire, is discovered alive and well, Twilight has her hooves full keeping the tyrannical king in check.
