What happens when Trixie switches places with Twilight? Nothing good at all. Both Trixie and Starlight wanted revenge on the purple unicorn so they worked together and traveled back in time to Rainbow Dash's first sonic rainboom.

When the damage was done though, there was no going back. Trixie caused some damage in canterlot but little did she know that the small amount of damage she did completely changed her future.

To her surprise, Trixie switched places with Twilight and Trixie now sees the world completely different. Starlight and Trixie are the only ponies who remember anything about when Twilight was the Princess of Friendship.

Now with Twilight being a showmare speaking in third person, Starlight and Trixie need to get time back on track but how?

Takes place before the season 5 finale
