Talk:The Times They Are A Changeling/@comment-25270260-20170102213152/@comment-5837525-20170104175111

Poor grammar and spelling aside, this quote is not "based on" anything, and the fact that the Mares of S.M.I.L.E. book's page is linked is more baffling.

Changelings don't act oppositely to whoever they're impersonating -- that runs completely counter to how they inherently operate. The point of a changeling taking a pony's place is that they have to mimic that pony's personality and mannerisms as closely as possible (Cadance's cheerfulness, Pinkie Pie's randomness, Applejack's country accent, etc). But it's not always perfect; another pony who knows that pony well enough will be able to notice if something is off.

We don't know what the real Crystal Hoof is like, if there even IS a real Crystal Hoof (like Herculine postulates above), or (if there is) if Thorax had even seen/met him beforehand. But Thorax's behavior while posing as Crystal Hoof is not a perfect indication of how the real one behaves, especially considering that Thorax wasn't trying to take anyone's place -- he simply wanted to blend in.
