My Little Pony: Friendship is Magic - Like Swiss cheese

So, the reason behind Chryssie' s ragged appearance isn't natural, but instead because she was essentially riddled with magical buckshot?

That's rather intense, even for the comic.

That doesn’t make any sense. Why do all the changelings have the same holes, etc. if Celestia just hit Chrysalis? And why could celestia curbstomp her then, in a foreign land--right after she had finished gorging on love no less--but do nothing when she attacked her in her own capital city?
