Yeah. We already know.

Of course, the Adaptational Alternate Ending one would also apply to "the Mysterious Mare-Do-Well" (as NONE of the Mane Six are the Mare-Do-Well in this one and the reason for the deception was more antagonistic).

And, for Adaptational Karma would also apply to Diamond Tiara getting punished for her bullying more often in general.
