Prior to the events of "A Canterlot Wedding" Princess Celestia asks Cadance what ought to be done with the changelings that have been discovered living hidden in Equestria. Cadance's proposed plan of action is swift, brutal, and ruthless, but absolutely unnecessarily so. Celestia has never heard Cadance speak an ill word of anyone, and she cannot fathom why the young princess seems to so despise the uncovered changelings.

Cadance just can't fathom why the uncovered changelings have chosen to forsake their own kind to live among the ponies.
