Cheerilee is everyone's favorite (and only) Ponyville teacher, as well as the wife of Changeling 77.
And she can control demons.
 Exasperated, Cheerilee tells Changeling #77 that Harry has been sitting in the corner for hours. After repeatedly asking what she did, Cheerilee admits she said "the B word". Disappointed she said that, 77 tries to convinve Harry that she's trying and that she's not a bigot. Harry, in bear gibberish, asks if she'll prove it by kissing him. 77 flatly rejects the idea, saying there are better ways to prove she's not a bigot, but Harry says something that sets him off and the two get into a tussle. Cheerilee shrugs, saying she's in the clear at least.
