A Sucessful Plan

The Mane 6 and Colt 6 are getting ready for Twilight and Dusk's coronation as rulers of Equestria but that has to be put on hold when a friend makes a terrible mistake that puts all of Equestria in danger.

(Basing this off the S9 finale which I have seen and using the fan subs)

There WILL be multiple alternate endings to this.
